# Introduction Welcome to the support pages for One Giant Leap's Gen. 3.0 range of paddle-sport power meters. {% hint style="success" %} If you have any questions, please send an email to {% endhint %} # Getting Started # Assemble your power meter To assemble the power meter you simply need to attach blades to each shaft section. This guide describes the process of fixing the blades in their correct position using the hot-melt glue included in with your power meter. {% hint style="danger" %} It is **very important** that the blades are aligned in the position described in this guide. {% endhint %} ## Step 1. Identify the shaft sections * The **left** shaft section has the length scale engraved * The **right** shaft section has the connection clamp ## Step 2. Test fit the blades * Check that the blades fit the shaft. Left blade onto the left shaft, and right blade onto the right shaft. *Note that shims may have been supplied with your power meter allowing you to adapt your blades to fit the shaft.* *These shims are to be glued to your blades first, allowing for a snug fit to the shaft.* * If the blades fit too tightly, try sanding the end of the shafts with 80 grit sandpaper to reduce the outside diameter slightly. * Measure the overall length of the paddle with the blades fitted. If you wish to shorten the shaft, you can trim the blade end of each shaft to achieve your desired length. Trim an **equal amount** from the end of each shaft. {% hint style="info" %} Example: If you want to reduce the paddle length by 3cm, cut 1.5cm from the end of each shaft. {% endhint %} {% hint style="info" %} You can cut the shaft with a hacksaw fitted with a fine-tooth blade or a metal cut-off wheel. Be sure to use the appropriate PPE for this task. {% endhint %} ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mihw1dqR0pzJyfeUW0J%2F-MisPzO4ys37Tqv-nbt-%2Fimage.png?alt=media\&token=39ffc39f-0e3a-4963-ba74-c0db271c9c6a) Leave the blades in fitted to the end of the shaft (not yet glued) and carry out the following steps ## Step 3. Apply masking tape to the shaft and blade * Apply masking tape to the throat of the blade. * Apply masking tape to the shaft where the shaft meets the blade. Perform this step for both left and right shafts. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b567Q2IAvRcu0OILg%2Fkayak1.JPG?alt=media\&token=c79734d2-d4b0-4921-8559-2b7d7ff80981) ## Step 4. Align the left blade with the length scale * Rotate the left blade to the position where the face of the left blade is aligned with the length scale (as shown below). ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5BkR2YkvkAHdEWwd%2Fkayak2.JPG?alt=media\&token=c2519bcb-f44c-461d-8644-4b8ed2edacca) ## Step 5. Mark the alignment of the left blade on the tape * Mark this alignment of the left blade using a pen on the tape applied in Step 3. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5O5i7Y2FePEpcneu%2Fkayak3.JPG?alt=media\&token=40822468-b092-4243-9c00-b30f8176ce15) ## Step 6. Glue the left blade in place using the hot melt glue * Remove the blade from the end of the shaft * Sand the end of the shaft with 80 grit sand paper to roughen the surface, allowing for good adhesion * Heat the glue stick with a heat gun until the stick becomes soft ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LQ8A6r0fD0hTyuKrAqo%2F-LQ8JzPHgXRtfWGb228F%2FIMG_20181031_151007.jpg?alt=media\&token=4aafe530-3fa6-49bc-abab-2a1bf06f455c) * Dab the softened glue stick onto the end of the paddle shaft, dabbing glue at several locations ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5ZFG28SbSC0jXmPg%2Fkayak4.JPG?alt=media\&token=89f1e0be-95df-4db6-8860-96d628ca7317) * Using a stick/trowel, spread the glue over end of the shaft. You will have to apply heat to the deposited glue to allow it to be worked smooth. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5eZHuy_6Y8jhfz2c%2Fkayak5.JPG?alt=media\&token=ec9a36d8-4b88-4bcf-86fa-01e07e5f6a96) * Prepare to glue the blade onto the shaft by reheating the applied glue as well as pre-heating the blade socket. Take care not to overheat the shaft or the blade during this stage. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5kRGK34oh1jSsrTl%2Fkayak6.JPG?alt=media\&token=69eee53d-e496-4344-b061-e65269af253d) * With the glue hot and the blade heated, assemble the blade onto the end of the shaft. Push the shaft all the way into the blade socket and then rotate the blade into the position where the alignment marks made during step 6. are aligned. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5O5i7Y2FePEpcneu%2Fkayak3.JPG?alt=media\&token=40822468-b092-4243-9c00-b30f8176ce15) * Remove any excess glue while it is still hot and easy to wipe away. {% hint style="info" %} Allow everything to cool down before applying force to the joint. Once cool, make sure that the marks remain aligned. If adjustment is required, heat up the join with a heat gun to re-activate the glue then twist the blade to align the marks. {% endhint %} ## Step 7. Assemble the shaft and set the blade offset angle to zero * Assemble the paddle shaft by joining the left and right shafts together * Set the blade offset angle to zero degrees ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b9xK41dzaT-VmvGmC%2Fkayak7.JPG?alt=media\&token=7819c389-574f-4c7a-a8a1-eccebadec33d) ## Step 8. Rotate the right blade so that it is aligned with the left blade. * Rotate the right blade so that it's alignment matches the left. {% hint style="info" %} At this stage the right blade should be fitted to the end of the right shaft, but not yet glued in place {% endhint %} * Alignment can be achieved by supporting both blades on a two level surfaces (see picture below). Be sure to support the each blade an equal distance from the blade tip. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LQ8A6r0fD0hTyuKrAqo%2F-LQ8PcVRP_tKcseqhWEL%2FIMG_20181031_144807.jpg?alt=media\&token=66685c5c-61fd-4444-be77-9e116fe1d3ef) ## Step 9. Mark the alignment of the right blade on the tape * Mark the alignment found in Step 8. on the right blade/shaft using a pen. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5O5i7Y2FePEpcneu%2Fkayak3.JPG?alt=media\&token=40822468-b092-4243-9c00-b30f8176ce15) ## Step 10. Glue the right blade in place using the hot melt glue * Same as before in Step 7.... * Heat the glue stick with a heat gun until the stick becomes soft * Dab the softened glue stick onto the end of the paddle shaft, dabbing glue at several locations * Using a stick/trowel, spread the glue over end of the shaft. You will have to apply heat to the deposited glue to allow it to be worked smooth. * Prepare to glue the blade onto the shaft by reheating the applied glue as well as pre-heating the blade socket. Take care not to overheat the shaft or the blade during this stage. * With the glue hot and the blade heated, assemble the blade onto the end of the shaft. Push the shaft all the way into the blade socket and then rotate the blade into the position where the alignment marks match up. * Remove any excess glue while it is still hot and easy to wipe away. * Let everything cool down. ## Step 11. Remove the masking tape * With both blades now glued into place, remove the masking tape. If there is any excess glue around the joint, then a bit of heat and a rag with turpentine will clean everything up nicely. ## Step 12. Waterproof the blade join *Corrosion is a natural enemy of any electronic product. Although fully-waterproofred, we want to limit the exposure of the internal surface of the load cell to salt water where at all possible. As One Giant Leap has no control over the quality of the hot melt glued bond that joins the blade to the shaft (as this task is performed by the end user), we recommended all customers to seal this joint with a combination of amalgamating tape and heat-shrink. Both the amalgamating tape and heat-shrink have been supplied with your Power Meter* * Peel the white backing from the amalgamating tape. Wrap the tape around the blade join, stretching it out as you do so. Stretching the tape allows the tape to amalgamate while compressing over the blade join. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-MATmehtOZ9Mj7LMvmF4%2F-MATssSUBEX61hPVSQQS%2Fimage.png?alt=media\&token=ea3e7575-515b-4239-ae72-9aec5f195ca6) * Slide the section of heat-shrink tubing onto the shaft and center it over amalgamating tape. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-MATmehtOZ9Mj7LMvmF4%2F-MATtBdq50dKdp6BaChV%2Fimage.png?alt=media\&token=b801bed0-d06e-4117-97f8-ea58b9b47432) * Using a heat gun, evenly heat the heat-shrink until it tightly wraps the shaft, smooth without ripples. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-MATmehtOZ9Mj7LMvmF4%2F-MATtaNYQQgy72Ejc-IV%2Fimage.png?alt=media\&token=5220340d-a1a1-4a62-a177-4ed15349363e) # Charge your power meter {% hint style="info" %} Your kayak power meter will have been shipped to you in deep sleep mode. Before the power meter will operate you will need to attach the wireless charger to the left shaft to force it out of deep sleep. {% endhint %} ## Charging time Charging a battery from empty to full should take around 3.5 to 4 hours. ## Charger placement ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2Fg9et2MBYl5VvBqZwenn5%2Fimage.png?alt=media\&token=5c4044c2-7f0d-46d5-a0fe-f2ab636737e8) locate the charger in line with the length scale and against the edge of the carbon shaft. A LED on the charger will blink green when you have it in the correct location. {% hint style="info" %} If the LED on the charger will blink red if the charger position is off. Remove the power supply from the charger to reset. {% endhint %} # Configure your power meter settings All of the settings need to be set **before** using your kayak power meter for the first time. Additionally, one or more of the settings may require **updating** whenever you: * change the location of your hands along the shaft * change your blade twist angle * change your overall paddle length * attach a new set of blades The settings can be set using the [Web Bluetooth App](/3.0/general/web-bluetooth-app), specifically the page. # Blade tip to hand distances The distance from the left blade tip to the left hand and the distance from the right blade tip to the right hand. ## Step 1. Attach the end of the measuring tape to the left blade tip ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FLdoPLxQBnzypVNck8VyW%2Fimage.png?alt=media\&token=265c1685-c0ad-4973-875d-366baee20c96) ## Step 2. Measure the distance from the left blade tip to the left hand * Measure from the left blade tip to the knuckle of the middle finger of the left hand (the hand closest to the left blade). * The **left blade tip to left hand distance** is 610mm in the example image below. ![the distance here is 610 mm](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-bJcDNnabu7DSFZzd6%2F-M-bNa-Qq9c0EXCSLdpb%2Fhand%20position.png?alt=media\&token=0985ead8-2b32-4a74-8ab8-e9ac348b3b98) ## Step 3. Attach the end of the measuring tape to the right blade tip ## Step 4. Measure the distance from the right blade tip to the right hand * Measure from the right blade tip to the knuckle of the middle finger of the right hand (the hand closest to the right blade). ## Step 5. Enter the distances into the 'Blade tip to hand distances' setting ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FMarmEW3qfeKypTgHJPMe%2Fimage.png?alt=media\&token=23c2ac23-edaa-4673-b760-912ebaaa07d7) # Blade tip to blade tip distance The distance between blade tip to blade tip. ## Step 1.

Measure the distance from the left blade tip to the right blade tip ![example: Blade tip to blade tip 2180mm](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2F0IqiEh3Y8763x2UI2tnT%2Fimage.png?alt=media\&token=30599ff4-357d-4170-b7ee-c1707699822d) ## Step 3. Enter the distance into the 'Blade tip to blade tip distance' setting ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FHFhCAhrzw8UHJSAFo1wn%2Fimage.png?alt=media\&token=fce8e5f9-74e6-4975-939d-f61a9553c91b) # Blade twist The hand which grips and twists the shaft/blade and the blade twist angle. ## Step 1. Determine the 'blade twist hand' * If you grip and twist the blade in your **right** hand (it rotates/slips in your left hand) then set blade offset twist hand to **Right Hand Twist**. * If you grip and twist the blade in your **left hand** (it rotates/slips in your right hand) then set blade offset twist hand to **Left Hand Twist**. ## Step 2. Determine the 'blade twist angle' ![Example: 60 degrees Right Hand Twist offset angle](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FTCwqG5fALjA290sx2hsY%2Fimage.png?alt=media\&token=11e17c62-fe54-4588-a894-39371b1795b5) ## Step 3.

Determine the make, model and size of the blades attached to the shaft ## Step 2. Select the blade type identified in Step 1. from the 'Blade type' setting ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2F4fWmhQ9uNBZYoB4hPb9V%2Fimage.png?alt=media\&token=aba8f81d-a23f-4cf6-8c1a-d784d6baa8ee) # Left blade tip to LED distance The distance from the left blade tip to the left datum and the distance from the right blade tip to the right datum. ## Step 1. Measure the distance from the left blade tip to the LED * Attach the tape measure to the tip of the **left blade** (as shown below). ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LAKe2MXA9oZcODl7DJ2%2F-LAKe6fE3yTp5yzYlV5h%2Fblade-tip.jpg?alt=media\&token=8df05e17-bf95-4e75-aba9-cb4a442f5290) * Measure the distance from the left blade tip to the LED. * In the example image below the measurement is 1020 mm. ![Example: Tip to LED is 1020mm](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FzIJvKCd6my3Ps4mORjar%2Fimage.png?alt=media\&token=217e7d0c-e2d0-4b4f-b361-210322c7ba2f) ## Step 3. Enter the distances into the 'Left blade tip to LED' setting ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FUcs8YFztjTvdDWE62rZI%2Fimage.png?alt=media\&token=4fa40e94-2a11-4ce0-bbcd-010b15a94994) # Calibration # Zero Offset The left shaft contains load cells which are used to measure the force being applied to the paddle. The output of a load cell when the shaft is experiencing no force is referred to as the **Zero Offset**. Each load cell has an associated zero offset. There are two load cells on a kayak power meter. The load cells have been designated channels **A** and **B.** The **Zero Offset** of a load cell can drift a small amount with a change in temperature. This is why manufacturers of power meters typically recommend performing a Zero Offset calibration on a semi-regular basis. A typical **Zero Offset** will change no more than 2-5 units between calibrations. A difference of 10 or more is an indication that either a bending force is being applied to the shaft, that there is an issue with that particular channel or that you recently travelled from an extremely hot or cold climate. {% hint style="info" %} After performing a number of Zero Offset calibrations, it will quickly become clear how frequently or infrequently a Zero Offset calibration is required. If the Zero Offsets vary by no more than **two** between calibrations, then there is little to be gained from performing a calibration regularly. {% endhint %} # Zero Offset calibration ## Step 1. Navigate to the [Calibration](https://app.onegiantleap.co.nz/calibration) page of the Web Bluetooth app and connect to the power meter ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FRSCLtWEReYwH8Z5UuozP%2Fimage.png?alt=media\&token=996a71ec-ea26-4fd8-9bdd-cb8c59859ac5) ## Step 2. Perform the Zero Offset Calibration * Make sure that the Power Meter is not experiencing any force when you perform the 'ZO' calibration. It's best practice to stand the paddle vertically by leaning it against a wall. This ensures that the shaft is experiencing as little bending as possible. * Click on "Zero Offset". The Zero Offsets will update automatically. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FlcByVQgqJx1MVoFCFKJJ%2Fimage.png?alt=media\&token=3d2b36f6-57d6-4416-ac74-f3524067c630) # Scale Factor A Scale Factor Calibration can be performed using basic and easily sourced components, or with a specifically designed calibration jig available for purchase from One Giant Leap. There is also the option to have the calibration jig manufactured yourself; the profile cut part files and assembly instructions are available to download from One Giant Leap . ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1RrRpHEgCplzwgRxMK%2F-M1RzWgzMq-okNnT3GaC%2Fimage.png?alt=media\&token=7c2d929b-c11e-4522-941a-66fc16c19ea5) ## Setup The calibration process requires the paddle to be setup in the following way: * Paddle shaft horizontal * Paddle assembled with the offset angle set to 90degrees **Right Hand Twist** * Supports located at the approximate blade centre and top hand positions * Calibration weights (with known weight) hung from the approximate bottom hand position ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LX1KxwqB6fAAyTdU0s-%2F-LX1LMRpHjQzCdLkszi8%2Fimage.png?alt=media\&token=75f8354d-1bc4-4737-9a80-fbfcec961dac) ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1RrRpHEgCplzwgRxMK%2F-M1Rxz0ZV7x2Ezd041-l%2Fimage.png?alt=media\&token=91c3697a-183e-417d-94ed-557541022e46) The supports can be as simple as blocks of wood resting on two separate tables. The space between the two tables is where the calibration weights will hang. Ideally the supports will have narrow width so that the paddle is supported at a definite spot which can be identified and measured. The calibration weights can be applied by suspending them from the shaft with a rope. The calibration process requires the strain output to be recorded with at least 2 different calibration weights (heaviest weight at least 20kg). The values are then input into the calibration spreadsheet where the scale factors are calculated. The A and B channels of a kayak power meter are calibrated separately, so the process must be carried out separately for each channel. # N channel Scale Factor calibration ## Step 1. Connect to the calibration page of the web app * Open the [Calibration ](https://app.onegiantleap.co.nz/calibration)page of the Web Bluetooth App and connect to your power meter * Measure and make note of the distance between the **left** blade tip and the LED. You will need to enter this value into the calibration spreadsheet in step 3. * Assemble paddle with offset angle at 90 degrees **Right Hand Twist** . ## Step 2.

You have completed the Kayak Power Meter scale factor calibration. # Advanced # Deep sleep {% hint style="info" %} Your power meter will enter a light sleep after 90 seconds of inactivity. A little movement will wake it up again. But if you are done for a few days, it is better to put your power meter into a deep sleep to best conserve your battery. You will need your charger to wake the shaft up from this deep sleep state, so keep that in mind before placing your power meter into deep sleep. {% endhint %} Connect to your power meter with the Web app and navigate to the configuration page ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2F2F6rQXMdA8kvPJY7kKCM%2Fimage.png?alt=media\&token=c0d6450d-06e7-4573-8c65-8b539ed41711) Click 'Confirm' and your power meter will disconnect and shutdown. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FfZyyxlFEwCWPmRy55kPy%2Fimage.png?alt=media\&token=150683c4-91ec-4900-8666-f5a56b1be3c9) When you want to wake your power meter up, simply place the charger on the shaft as if you were going to charge it. It should only take about 3-5 seconds for the charger to wake up your power meter. # Adjust your clamp You can increase or decrease the clamp tightness by adjusting the screws on the clamp mechanism: ## Step 1. Tighten or loosen the clamp screw * Use a Phillips-head screwdriver. Clockwise will tighten the clamp, counterclockwise will loosen the clamp. If it requires more than a gentle force to lock the clamp with the left shaft in, it is probably too tight and should be loosened. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0kfE-xWxXfuD6yAQk-%2FIMG_0832.jpg?alt=media\&token=d1e31786-fac3-4b46-b174-2be78ac00c70) # Remove and attach your sleeve The following instructions explain how to remove and install the clamp sleeve. A clamp sleeve of a different length can be fitted to lengthen or shorten the shaft. ## Step 1. Remove the existing sleeve * The sleeve is fitted to the shaft with hot-melt glue. Using a heat gun, heat up the glued end of the sleeve. The glued section is 75mm long. Take care not to overheat the shaft by heating gradually and frequently checking to see if the glue connection can be separated. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0khdB5-J4Bc2GN-8UJ%2F75mm.png?alt=media\&token=21ec0810-61cc-4b94-9140-e1b12e3db034) ## Step 2. Apply masking tape to the shaft * Allow a 35mm spacing between the end of the shaft and the edge of the tape. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0khkVHJHi9pP573Ra9%2F35mm.png?alt=media\&token=2b69afe4-59dc-4b42-a310-408f638109fe) ## Step 3. Apply tape to the end of the clamp sleeve ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0khqqfH5Hx956EuqCC%2FIMG_0839.jpg?alt=media\&token=3bd21f43-784f-4678-acf9-01c3f60ea569) ## Step 4. Apply hot-melt glue to the spigot section of the shaft * Heat and spread evenly. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FJ68uu7k6WeDm0IULK36F%2Fimage.png?alt=media\&token=8bfccbb2-b235-4b40-ae48-2f870afb7ed5) ## Step 5. Heat up the glue on the shaft and pre-heat the clamp sleeve ## Step 6. Assemble the clamp sleeve onto the shaft * When the glue becomes melted and the clamp shaft warm, quickly assemble the clamp sleeve onto the shaft. Slide the clamp sleeve down the shaft until the bottom edge meets the tape applied in Step 2. Roughly align the “0 degree” marking on the clamp with the datum mark on the shaft. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0khzVcT-U5ccJFRQj_%2FIMG_0842.jpg?alt=media\&token=5f854397-dc7e-4063-bf45-6fcc3934f0eb) ## Step 7. Carefully assemble the left and right shafts of the power meter together * Clamp and set the offset angle to zero degrees. Take care as the hot-melt glue joint will still be hot and not yet set. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0kiCjgFo9Ef00zGJyM%2FIMG_0843.jpg?alt=media\&token=501b20a7-6c72-491a-82ea-03d4959e6822) ## Step 8. Align the left and right blades * Align the left and right blades by placing both blades down onto two level surfaces. The hot melt glue joint will rotate to it's correct position. If not, apply more heat to the sleeve to reactivate the glue. Make sure the left and right blades are supported an equal distance from the tip. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Miy-z1ykAIE8hCeXEj3%2F-Miy10iBJg35pvvDoxjX%2Fimage.png?alt=media\&token=dc909104-de2e-4586-b4b6-c4773e7b987c) ## Step 9. Allow the hot melt glue to cool and set and then remove the masking tape * Applying the heat gun to any excess glue on top of the tape will allow the tape to be removed easily, removing the excess glue with it. * Any remaining excess hot melt glue can be rubbed away using Mineral Turpentine soaked rag. # Getting Started Let's get that power meter sussed! This section covers all canoe power meters: * Outrigger power meter * SUP power meter * High Kneel power meter * Canoe Slalom power meter * Dragon boat power meter \ # Assemble Putting it all together ## Step 1. Fit and attach the blade {% hint style="info" %} For this part of the assembly you will need the black hot-melt glue (included with your power meter), a mixing stick, heat gun, power meter shaft, and your blade. *Note that shims may have been supplied with your power meter allowing you to adapt your blades to fit the shaft.* *These shims are to be glued to your blades first, allowing for a snug fit to the shaft.* {% endhint %} ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SNnU3oG9GBRlU0kIs%2Fdb-items-required1.png?alt=media\&token=92c22aa9-c17b-4596-adf8-253a415d7829) ### A.

Attach and align the blade While the glue is warm and malleable, insert the blade spigot into the blade end of your power meter shaft. Align the blade and shaft using the LED light placement and the end of the blade. If your blade has a 'front face' (the face that receives the force of the water), make sure it is this face that is aligned with the LED. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SQf_-Z0LyIJOq0cHM%2Fdb-attach-align.png?alt=media\&token=f20e575d-b81f-4486-abd7-6b9d6fd551be) ### D. Clean up Any excess glue can easily be removed with a bit of direct heat and a swipe or two of a rag with turpentine. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SRF-tI27-cOQx1L2m%2FIMG_0800.JPG?alt=media\&token=1d7e2e90-b4e5-45e7-b7f5-1bd4ccb59c9d) ## Step 2. Waterproof the blade join *Corrosion is a natural enemy of any electronic product. Although fully-waterproofed, we want to limit the exposure of the internal surface of the load cell to salt water where at all possible. As One Giant Leap has no control over the quality of the hot melt glued bond that joins the blade to the shaft (as this task is performed by the end user), we recommended all customers to seal this joint with a combination of amalgamating tape and heat-shrink. Both the amalgamating tape and heat-shrink have been supplied with your Power Meter* ### A. Apply amalgamate Peel the white backing from the amalgamating tape. Wrap the tape around the blade join, stretching it out as you do so. Stretching the tape allows the tape to amalgamate while compressing over the blade join. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Miy2WpSaorNMG7XXGtH%2F-Mj6HG2KuVXLACf6NyLD%2Fimage.png?alt=media\&token=4953a813-499b-4fb5-a7f7-df53959a4aaa) ### B. Apply heat shrink Slide the section of heat-shrink tubing onto the shaft and center it over amalgamating tape. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Miy2WpSaorNMG7XXGtH%2F-Mj6I-QME0PbeK7FVFhg%2Fimage.png?alt=media\&token=3c823f10-1d0b-493e-bf4c-5e0acde0b027) Using a heat gun, evenly heat the heat-shrink until it tightly wraps the shaft, smooth without ripples. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mj6IgW5QuXYDtFd-qi0%2F-Mj6KzU8NH1zqrsK8_Yc%2Fimage.png?alt=media\&token=07d556be-53df-4a03-961f-b8a4cc58009c) ## Step 3. Fit and attach handle {% hint style="info" %} For this part of the assembly you'll need the black hot-melt glue stick, mixing stick, heat gun, power meter shaft with attached blade, and your handle {% endhint %} ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SRm74G77nRGq08wP3%2Fdb-items-required2.png?alt=media\&token=e4336362-e9dc-4ff6-a27f-4ba05d5fb66f) ### A. Measure paddle length Test fit the handle and shaft, setting the handle to the correct position to achieve the desired paddle length. Ensure that there is **at least 75mm** of handle spigot inserted into the shaft. If the paddle is too long and inserting the handle all of the way into the sleeve doesn't allow you to achieve your desired length, now is the time to shorten your power meter. OGL recommends trimming the sleeve section of the shaft (the section of shaft that the handle slips into). The sleeve is a replaceable component of your power meter shaft and you can purchase un-cut sleeves from OGL if you want to restore your power meter back to full length. If your power meter has an adjustable clamp fitted, you will need to remove the sleeve from the shaft and trim the glued end of the spigot. (refer to the Advanced guide on removing your sleeve). If no clamp is fitted, you can trim the handle end of the sleeve without having to remove it from the shaft. ![Clamp sleeve to be removed before trimming](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FRh4AaLalOPTLbaEg1vFv%2Fimage.png?alt=media\&token=9e08a6fd-c27c-4a39-94b9-ee092adfa674) ![Without a clamp fitted, the shaft can be trimmed at the handle end](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FssWB7XVqFSSvTR1SJn3h%2Fimage.png?alt=media\&token=2f45d5df-3a68-4494-867c-78e2500828dd) To achieve a very short paddle, you may need to trim the end handle spigot too. This will be apparent when the handle 'bottoms out' in the sleeve. When calculating hot much to trim from the handle, be sure that there is at least **75mm** of handle spigot inserted into the sleeve to achieve a strong connection. {% hint style="info" %} You can cut the shaft with a hacksaw fitted with a fine-tooth blade or a metal cut-off wheel. Be sure to use the appropriate PPE for this task. {% endhint %} ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mihw1dqR0pzJyfeUW0J%2F-MisPzO4ys37Tqv-nbt-%2Fimage.png?alt=media\&token=39ffc39f-0e3a-4963-ba74-c0db271c9c6a) If you have a glue-in handle, test fit the handle once again after any trimming has been completed. Mark the desired handle depth with a pencil so that you can see the correct depth when attaching the handle with hot-melt glue. ### B. Apply glue to handle spigot (for glue-in handles) ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LXWvTncgxeIHZYmbtxJ%2F-LXWvvkRm0_jdV3kTK9p%2Fimage.png?alt=media\&token=87d4cd4a-7df0-482c-8dce-72e602f1217b) ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LXWvTncgxeIHZYmbtxJ%2F-LXWw-5PkWXUjIXxDZJY%2Fimage.png?alt=media\&token=df9f29ef-6e79-45bf-805b-829e8de74c22) ### C. Attach and align the handle (for glue-in handles) The handle will be aligned so that it is parallel with the end of the blade. Since we already aligned and attached the blade, this part is pretty easy. With the glue still hot and malleable, inset the handle into the sleeve. Make sure to insert the handle to the measured pencil marking we made in 3.A. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SUdL-o9gmgt-ai3hH%2Fdb-attach-align2.png?alt=media\&token=e28bb0b6-eb74-4e0c-a0ef-fbfffb806f11) ### D. Clean Up (for glue-in handles) Same as before, a bit of heat and a rag with turpentine will quickly remove and excess glue.
Assembled!
# Charge Power up Your power meter will need a good charge before your first use. Your charger needs to be aligned properly to charge, so take note of the images below and how the charger is attached. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SWU0yYQpU67YgBmCL%2FIMG_0791.JPG?alt=media\&token=a3345c00-703f-4ea7-b847-04fd84e53105) ![Charger located directly over the LED](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SWc8YCu5B6nFEZiSt%2FIMG_0793.JPG?alt=media\&token=2366495a-9177-46a4-89c7-7c8963a5bd51) When the charger is aligned properly, a green light will flash on the charger to let you know it is working properly. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SXjQJGWp0a98cY_sB%2FIMG_0792.JPG?alt=media\&token=4512e36e-3a46-4b31-994a-fd0ee596c3c3) {% hint style="info" %} You power meter needs to charge for at least four hours to give it a full charge. {% endhint %} {% hint style="success" %} The green LED on your power meter will blink and let you know how much battery is left. 5 blinks = 100%, 4 blinks = 80%, 3 blinks = 60%, 2 blinks = 40%, 1 blink = 20%. If your power meter has less than 10% battery left, it will give a rapid blink and shutdown. {% endhint %} # Configure Configure your power meter settings All of the settings need to be set **before** using your power meter for the first time. Additionally, one or more of the settings may require **updating** whenever you: * change the location of your hands along the shaft * change your overall paddle length * attach a new set of blades The settings can be set using the [Web Bluetooth App](/3.0/general/web-bluetooth-app), specifically the page. ## 1. Connect Make sure your power meter is on and connect via our [OGL app](https://app.onegiantleap.co.nz) * Press the '+' icon shown in the top right hand corner and select your power meter from the drop-down list. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mj6exArYl9YKiywCCx7%2F-Mj6o3LVsmeY4BS7oCqt%2Fimage.png?alt=media\&token=c5f122d3-22ad-4bfb-9533-3d6689564a2f) * Press the hamburger menu icon in the top left corner and select the 'configuration' page. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mj6exArYl9YKiywCCx7%2F-Mj6y8reKkvo88s6yYJe%2Fimage.png?alt=media\&token=33b15dbe-b467-41c3-8e88-489774988232) Everything should look pretty similar to the screenshot above. We need to fill in the 'Blade tip to hand distances' the 'Blade tip to LED distance' and select the correct 'blade type' to properly configure your power meter for use. ## 2. Measuring blade tip to hand distances ### A. Measuring blade tip to top hand Place then end of the tape measure on the tip of the blade and measure to the top hand position. The top hand position is located in the mid-point of the handle grip. Write down the measurement, we'll input it in a bit. ![Top hand distance here is 1250 mm](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-X4HEOd-xWKEXKTfeA%2F-M-X9h82dBiXF0sAAcfD%2Ftop%20hand%20position.png?alt=media\&token=d2901c30-42cc-417b-b183-f298b3ce0e1c) ### B. Measuring blade tip to bottom hand Same as before, place the end of the tape measure on the tip of the blade and measure to the bottom hand position. The bottom hand position is located at the middle finger knuckle. Make a note of the measurement. ![Bottom hand distance here is 610 mm](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-X4HEOd-xWKEXKTfeA%2F-M-X9sfIkbyhxsb1PmgY%2Fbottom%20hand%20position.png?alt=media\&token=3642a40b-eb91-49b3-901e-2a4a027f0682) {% hint style="success" %} To make sure the power meter operates with consistent accuracy, it is important that your bottom hand location does not deviate from your bottom hand measurement. It is highly recommended to tape the shaft at the location, similar to the image below {% endhint %} ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LXWxFsNeIHMaEMm7JOF%2F-LXX66K9zxrqG5ANSAew%2Fimage.png?alt=media\&token=bfae2d2b-0131-435d-ab75-3af9227dacd1) ## 3. Measuring blade tip to LED distance Same as before, tape measure on the tip of the blade and measure to the LED, as shown below. ![Example: Tip to LED is 810mm](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LAFl-quJvXSIV-V8Y2Z-782413134%2Fuploads%2FdltavyYHrG3oOccNYOV9%2Fimage.png?alt=media\&token=ce04037d-a5df-4096-9d5a-99c786ff1085) ## 4. Enter measurements click on the 'Blade tip to hand distances field and enter you measurements. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mj6exArYl9YKiywCCx7%2F-Mj6q6AkQDKmkKLb9eoJ%2Fimage.png?alt=media\&token=cb2d356b-edb2-46fd-8d8b-ee8aec221651) ## 5. Select blade type click on the 'Blade type' and select your blade type from the list of options. {% hint style="info" %} This option isn't required for Dragon boat power meters {% endhint %} # Calibration # Zero Offset The power meter shaft contains load cells which are used to measure the force being applied to the paddle. The output of a load cell when the shaft is experiencing no force is referred to as the **Zero Offset**. Each load cell has an associated zero offset. There is one load cells in a canoe power meter. This load cell has been designated as channels **A.** The **Zero Offset** of a load cell can drift a small amount with a change in temperature. This is why manufacturers of power meters typically recommend performing a Zero Offset calibration on a semi-regular basis. A typical **Zero Offset** will change no more than 2-5 units between calibrations. A difference of 10 or more is an indication that either a bending force is being applied to the shaft, that there is an issue with that particular channel or that you recently travelled from an extremely hot or cold climate. {% hint style="info" %} After performing a number of Zero Offset calibrations, it will quickly become clear how frequently or infrequently a Zero Offset calibration is required. If the Zero Offsets vary by no more than **two** between calibrations, then there is little to be gained from performing a calibration regularly. {% endhint %} # Perform a ZO calibration ## Step 1. Navigate to the [Calibration](https://app.onegiantleap.co.nz/calibration) page of the Web Bluetooth app and connect to the power meter ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Miso-OLVvnZSP24ZL6q%2F-Mit2qVG32UvIK9GsFEr%2Fimage.png?alt=media\&token=970864b5-d288-40e5-834b-c19609193d9a) ## Step 2. Perform the Zero Offset Calibration * Make sure that the Power Meter is not experiencing any force when you perform the 'ZO' calibration. It's best practice to stand the paddle vertically by leaning it against a wall. This ensures that the shaft is experiencing as little bending as possible. * Click on "Zero Offset". The Zero Offsets will update automatically. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Miso-OLVvnZSP24ZL6q%2F-Mit39rLg8ylM1T8offI%2Fimage.png?alt=media\&token=a2e20816-997b-434d-8be0-d2e92402282c) # Scale Factor A Scale Factor Calibration can be performed using basic and easily sourced components, or with a specifically designed calibration jig available for purchase from One Giant Leap. There is also the option to have the calibration jig manufactured yourself; the profile cut part files and assembly instructions are available to download from One Giant Leap . ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1RrRpHEgCplzwgRxMK%2F-M1RzWgzMq-okNnT3GaC%2Fimage.png?alt=media\&token=7c2d929b-c11e-4522-941a-66fc16c19ea5) ## Setup The calibration process requires the paddle to be setup in the following way: * Paddle shaft horizontal * Supports located at the approximate blade centre and top hand positions * Calibration weights (with known weight) hung from the approximate bottom hand position ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mj7033x2YE21a_QP4tA%2F-Mj8oTH-90WCDjzhjFtb%2Fimage.png?alt=media\&token=2493e07e-a12c-4669-8948-f7b8c23f72c2) The supports can be as simple as blocks of wood resting on two separate tables. The space between the two tables is where the calibration weights will hang. Ideally the supports will have narrow width so that the paddle is supported at a definite spot which can be identified and measured. The calibration weights can be applied by suspending them from the shaft with a rope. The calibration process requires the strain output to be recorded with at least 2 different calibration weights (heaviest weight at least 20kg). The values are then input into the calibration spreadsheet where the scale factors are calculated. # A channel Scale Factor calibration ## Step 1. Connect to the calibration page of the web app * Open the [Calibration ](https://app.onegiantleap.co.nz/calibration)page of the Web Bluetooth App and connect to your power meter * Measure and make note of the distance between the blade tip and the LED. You will need to enter this value into the calibration spreadsheet in step 3. ## Step 2. Place the paddle onto the calibration jig * Place the paddle onto the calibration jig with the blade **face down** on to the Blade Support * The blade should be supported near its centre * The shaft support should be approximately at the top hand position ## Step 3. Measure and enter distances into the calibration spreadsheet {% hint style="info" %} Contact to request a calibration spreadsheet to be sent to you. {% endhint %} * **Tip to blade support:** The distance from the blade tip to the centre of the blade support. * **Tip to shaft support:** The distance from the blade tip to the centre of the shaft support (near the handle). * **Tip to calibration weight:** The distance from the blade tip to the position where the calibration weight will be applied. It is helpful to mark this location with masking tape so when it comes time to applying the calibration weight you can hang the weight in the correct location * **Left tip to LED:** The distance from the left blade tip to the LED, measured in Step. 1 ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mj7033x2YE21a_QP4tA%2F-Mj8r2hnt9_9oiHQHQZG%2Fimage.png?alt=media\&token=6fdcbf31-b7a7-4b12-897a-df42ff471d81) ## Step 4. Record the zero-load outputs With the paddle in position, but without any load applied, record the live output of channel **A** as shown in the [Calibration ](https://app.onegiantleap.co.nz/calibration)page of the Web Bluetooth App and enter this into the first row of the calibration spreadsheet. Read the paddle angle from the Web Bluetooth App and enter this into the first row as well. {% hint style="info" %} The angle should be close to 0 degrees if you have fitted the blade correctly with the blade face aligned with length scale. {% endhint %} ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mj7033x2YE21a_QP4tA%2F-Mj8rid00IT5e8loBz8C%2Fimage.png?alt=media\&token=44fd3f1b-9cb8-4ab7-9705-d4e149a212ae) ## Step 5. Apply weight to the shaft * Hang a calibration weight off the shaft at the location measured in Step 3*.* * Record the live outputs of channel **A** and the shaft angle in the second row of the spreadsheet. * Enter the mass of the applied weight into the spreadsheet. Don't forget to include the weight of the rope, hook or bucket used to suspend the weight. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mj7033x2YE21a_QP4tA%2F-Mj8uIAM4cHJ4aJs_rCu%2Fimage.png?alt=media\&token=8c60adee-bfab-4426-8c2f-41b5c1ffd407) * Add another calibration weight to increase the load applied to the paddle. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mj7033x2YE21a_QP4tA%2F-Mj8wSpjsr9tsk7we3S_%2Fimage.png?alt=media\&token=9294e21a-d510-4d15-b9d8-9314fa1a54ef) {% hint style="info" %} You can extend the calibration spreadsheet to 3 or more points of calibration if you wish. To do this, repeat the steps above recording the A channel output, angle and calibration weight in a new row of the spreadsheet. Ensure the position of the calibration weight, the blade support and the shaft support remain the same for each point in the calibration process. {% endhint %} ## Step 6. Remove the calibration weights Remove the calibration weights from the paddle and remove the paddle from the jig. ## Step 7. Enter the LED to Load Cell distance Enter the Datum to Load Cell distances into the spreadsheet * Generation 3.0 power meters: LED to Load Cell = 0.0395m * Generation 3.x power meters: LED to Load Cell = 0.xxxxm ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mj8wjvXoHDhmoN6zPAy%2F-Mj8wubKb2sYbFQC1-LA%2Fimage.png?alt=media\&token=c6fb5632-7914-4026-a7a4-bebb1bd850f9) ## Step 8.

The sleeve is a replaceable component of your power meter. A sleeve of a different length can be fitted to lengthen or shorten the shaft. ## Step 1. Remove the existing sleeve * The sleeve is fitted to the shaft with hot-melt glue. Using a heat gun, heat up the glued end of the sleeve. The glued section is 75mm long. Take care not to overheat the shaft by heating gradually and frequently checking to see if the glue connection can be separated. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0khdB5-J4Bc2GN-8UJ%2F75mm.png?alt=media\&token=21ec0810-61cc-4b94-9140-e1b12e3db034) ## Step 2. Apply masking tape to the shaft * Allow a 35mm spacing between the end of the shaft and the edge of the tape. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0khkVHJHi9pP573Ra9%2F35mm.png?alt=media\&token=2b69afe4-59dc-4b42-a310-408f638109fe) ## Step 3. Apply tape to the end of the clamp sleeve ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0khqqfH5Hx956EuqCC%2FIMG_0839.jpg?alt=media\&token=3bd21f43-784f-4678-acf9-01c3f60ea569) ## Step 4. Apply hot-melt glue to the spigot section of the shaft * Heat and spread evenly. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Miy-z1ykAIE8hCeXEj3%2F-Miy0bVX47QiSyPwNpIK%2Fimage.png?alt=media\&token=6c600607-ab3d-4c52-9719-db237ac406a0) ## Step 5. Heat up the glue on the shaft and pre-heat the sleeve ## Step 6. Attach the clamp sleeve onto the shaft * When the glue becomes melted and the clamp shaft warm, quickly assemble the sleeve onto the shaft. Slide the clamp sleeve down the shaft until the bottom edge meets the tape applied in Step 2. Align the “0 degree” marking on the clamp with the LED. ![](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-Mj6bPgHFq8rY3ftBVCi%2F-Mj6dvjsum-Ir32ZQF2f%2Fimage.png?alt=media\&token=dde9d2f8-c930-4374-b75b-72e71be05e74) ## Step 7. Allow the hot melt glue to cool and set and then remove the masking tape * Applying the heat gun to any excess glue on top of the tape will allow the tape to be removed easily, removing the excess glue with it. * Any remaining excess hot melt glue can be rubbed away using Mineral Turpentine soaked rag. # Web Bluetooth App The Web Bluetooth App can be accessed at using one of the supported platforms listed [below](/3.0/general/web-bluetooth-app#supported-platforms). {% hint style="info" %} After visiting the Web Bluetooth app for the first time, an internet connection is **not** required for future visits to the Web Bluetooth app. This is because the Web Bluetooth app is cached (downloaded in the background) on your phone/computer so it becomes available to use when offline.

The **Power Meter w/ High Speed Data** builds on the physiology focused features of the **Power Meter** and adds biomechanics/technique focused features in the form of additional real-time metrics and the introduction of High Speed Data. The features of the **Power Meter w/ High Speed Data** are a superset of those found in the **Power Meter**. We encourage those who aren't sport scientists or researchers; those who don't have access to a sport scientist or a highly analytical coach, or those who aren't part of a national team (where access to sport science expertise is a safe assumption and team boat paddling is common) to opt for the **Power Meter** as the additional features of the **Power Meter w/ High Speed Data** may not be effectively utilized in all cases. On the flip-side, if you have access to a sport scientist (particularly if they have a background in biomechanics) and/or team boat paddling is common (where detailed stroke-timing between athletes may be investigated) then we strongly recommend opting for the **Power Meter w/ High Speed Data**. {% content-ref url="/pages/-LO-rGQjpk3L-C3y7KYd" %} [Power Meter](/3.0/general/model-descriptions/power-meter) {% endcontent-ref %} {% content-ref url="/pages/-LO-rPCwn2L7H1rtHCfJ" %} [Power Meter w/ High Speed Data](/3.0/general/model-descriptions/power-meter-w-high-speed-data) {% endcontent-ref %} # Power Meter ## Power Meter (USD$1,099) * BLE/ANT+ real-time (per-stroke) metrics for display/collection on BLE/ANT+ head-units * Stroke Power, Strokes Per Minute and Stroke Power Balance available on all compatible devices e.g. Garmin, Polar and Suunto # Power Meter w/ High Speed Data ## Power Meter w/ High Speed Data (USD$1999) * BLE/ANT+ real-time (per-stroke) metrics for display/collection on BLE/ANT+ head-units * Average Stroke Power, Strokes Per Minute and Average Stroke Power Balance available on all compatible devices e.g. Garmin, Polar and Suunto * On-board memory to record a minimum of 4 hours of High Speed Data (nominally 100Hz with up to 200Hz proposed) in .fit file format * High Speed Data from the left and the right shafts are automatically synchronized, combined into a single .fit file and recorded in a single location (the right shaft) for ease of download. * Wireless downloading of High Speed Data over ANT (download over BLE proposed) * High-accuracy clock enables time-synchronization of High Speed Data with other data sources such as High Speed Data from additional power meters (e.g. K2 or K4) or video, boat acceleration, GPS boat speed etc. * UTC time-synchronization requires a GPS sync box (sold separately) and the syncing process occurs automatically over-the-air (i.e. no cables). ### High Speed Data (100Hz) Metrics for Power Meter w/ High Speed Data * Top Hand Force * Bottom Hand Force * Top Hand Power * Bottom Hand Power ![High Speed Data example showing average power and top and bottom hand forces](https://3210906295-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LNXUCNQ8hTVx78mLMEz%2F-LNXUGTgWbf272gGFXis%2Fimage.png?alt=media\&token=ff6b0fb0-dceb-490b-816f-58f0bb81cf02) # Firmware Changelog ## 0.1.29 - 2019-02-27 {% file src="/files/-LZhqZ3bChZQ5RSiATDF" %} 0.1.29 {% endfile %} ### Fixed * Correct power values depended on having zero offsets that were accurate to a level that in practice was difficult to achieve. This is no longer the case. * When recording High Speed Data, a number of samples were being discarded and not recorded to the .fit file. This has now been fixed. * Some power meters exhibited occasional erroneous values in the output column of the Calibration page. The underlying issue has now been resolved. ### Changed * Power/force is now being measured in the thrust plane only (the plane normal to the blade face). Only a negligible amount power/force is generated in the orthogonal plane, so this change shouldn't have a noticeable affect on the total power values. * The LED represents the remaining battery capacity (when not charging) and no longer represents the connection state. Every five seconds the LED on each shaft will blink for a short period up to five times. Five blinks represents 80-100% capacity, four blinks represents 60-80% capacity etc. The LED blink will switch to 'breathing' mode when charging (on for one second, off for one second). This 'breathing' will change to on for 5 seconds, off for 10ms when the shaft is fully charged. * The transmit power for the bicycle power meter ANT+ channel has been increased from 0dBm to +4dBm. ### Added * The firmware version running on the left shaft (kayak) is now displayed in the Web Bluetooth app. ## 0.1.21 - 2018-12-05 {% file src="/files/-LSuFHgjM4s4oSl8fvUQ" %} 0.1.21 {% endfile %} ### Fixed * The 'Power balance' metric was found to favour one side of the stroke. This has now been fixed. ### Changed * ANT+ displays will now correctly interpret the power values as per stroke (rather than per second) and subsequently store them in the .fit file in a physiologically appropriate manner where each sample represents the average power output over the recording interval (typically 1s). * The battery state of the left shaft (kayak) is communicated by the right shaft (kayak) to the Web Bluetooth app using a *different* protocol (to support Polar head-units and accessing the Web Bluetooth app on iOS). Web Bluetooth app v0.0.17 or higher is required to correctly receive the left shaft battery state. ### Added * Support for Polar head-units (tested with M460 and V800). ## 0.1.14 - 2018-11-23 {% file src="/files/-LSuJo108lL90\_zXuSeK" %} 0.1.14 {% endfile %} ### Fixed * Deep sleep mode triggering issues. ### Changed * Increased wake-up motion threshold from 750mg to 1000mg. * The left shaft (kayak) no longer appears as a cycling power meter to prevent the user accidentally connecting to the left shaft over Bluetooth (when the right shaft (kayak) is asleep) when using e.g. the Wahoo 'Fitness' app. ### Added * Active gain error compensation of the load cells analog-to-digital converter. * Support for the Kayak Power Meter model (without High Speed Data). # Manufacturer's Warranty One Giant Leap's power meters are warranted to be free from defects in materials or workmanship for one year from the date of purchase.

This guide describes the process of fixing the blades into the correct position with hot-melt glue included in with your power meter. {% hint style="danger" %} It is **very important** that the blades are 'aligned' with the zero angle of each shaft section. {% endhint %} ## Step 1. Identify the shaft sections * The **left** shaft section has the length scale and it is the shortest of the two shaft sections. * The **right** shaft section has the connection clamp and it is the longest of the two shaft sections. ## Step 2. Slide the blades onto the shaft (without applying glue) * Check that the blades fit the shaft. Left blade onto the left shaft, and right blade onto the right shaft. * If the blades fit too tightly, try sanding the end of the shafts with 80 grit sandpaper to reduce the outside diameter slightly. Leave the blades in fitted to the end of the shaft (not yet glued) and carry out the following steps ## Step 3. Apply tape to the shaft and blade * Apply tape to the throat of the blade. * Apply tape to the shaft where the shaft meets the blade. {% hint style="info" %} Power meters purchased directly from One Giant Leap will have masking tape already applied to the shaft at the correct position (i.e. 295mm from the datum). {% endhint %} Perform this step for both left and right shafts. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b567Q2IAvRcu0OILg%2Fkayak1.JPG?alt=media\&token=c79734d2-d4b0-4921-8559-2b7d7ff80981) ## Step 4. Align the left blade with the zero angle * Rotate the left blade on the end of the left shaft to the position where the face of the left blade is aligned with the zero angle (as shown below). ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5BkR2YkvkAHdEWwd%2Fkayak2.JPG?alt=media\&token=c2519bcb-f44c-461d-8644-4b8ed2edacca) ## Step 5. Mark the alignment of the left blade on the tape * Mark this alignment of the left blade using a pen on the tape applied in Step 3. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5O5i7Y2FePEpcneu%2Fkayak3.JPG?alt=media\&token=40822468-b092-4243-9c00-b30f8176ce15) ## Step 6. Glue the left blade in place using the hot melt glue * Remove the blade from the end of the shaft * Sand the end of the shaft with 80 grit sand paper to roughen the surface, allowing for a good surface for adhesion * Heat the glue stick with a heat gun until the stick becomes soft ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LQ8A6r0fD0hTyuKrAqo%2F-LQ8JzPHgXRtfWGb228F%2FIMG_20181031_151007.jpg?alt=media\&token=4aafe530-3fa6-49bc-abab-2a1bf06f455c) * Dab the softened glue stick onto the end of the paddle shaft, dabbing glue at several locations ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5ZFG28SbSC0jXmPg%2Fkayak4.JPG?alt=media\&token=89f1e0be-95df-4db6-8860-96d628ca7317) * Using a stick/trowel, spread the glue over end of the shaft. You will have to apply heat to the deposited glue to allow it to be worked smooth. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5eZHuy_6Y8jhfz2c%2Fkayak5.JPG?alt=media\&token=ec9a36d8-4b88-4bcf-86fa-01e07e5f6a96) * Prepare to glue the blade onto the shaft by reheating the applied glue as well as pre-heating the blade socket. Take care not to overheat the shaft or the blade during this stage. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5kRGK34oh1jSsrTl%2Fkayak6.JPG?alt=media\&token=69eee53d-e496-4344-b061-e65269af253d) * With the glue hot and the blade heated, assemble the blade onto the end of the shaft. Push the shaft all the way into the blade socket and then rotate the blade into the position where the alignment marks made during step 6. are aligned. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5O5i7Y2FePEpcneu%2Fkayak3.JPG?alt=media\&token=40822468-b092-4243-9c00-b30f8176ce15) * Remove any excess glue while it is still hot and easy to wipe away. Allow the blade and shaft to cool down before applying any force to either. Once cool, make sure that the alignment marks remain aligned. If adjustment is required, heat up the join with a heat gun to re-activate the glue then twist the blade to align the marks. ## Step 7. Assemble the shaft and set the blade offset angle to zero * Assemble the paddle shaft by joining the left and right shafts together * Set the blade offset angle to zero ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b9xK41dzaT-VmvGmC%2Fkayak7.JPG?alt=media\&token=7819c389-574f-4c7a-a8a1-eccebadec33d) ## Step 8. Rotate the right blade so that it is aligned with the left blade. * Rotate the right blade so that it's alignment matches the left. At this stage, the right blade should be fitted to the end of the right shaft, but not yet glued in place. * Alignment can be achieved by supporting both blades on a two level surfaces (see picture below). Be sure to support the each blade an equal distance from the blade tip. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LQ8A6r0fD0hTyuKrAqo%2F-LQ8PcVRP_tKcseqhWEL%2FIMG_20181031_144807.jpg?alt=media\&token=66685c5c-61fd-4444-be77-9e116fe1d3ef) ## Step 9. Mark the alignment of the right blade on the tape * Mark this alignment of the right blade using a pen on the tape applied in Step 3. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-b0bTuU8ch2QFLNPGK%2F-M-b5O5i7Y2FePEpcneu%2Fkayak3.JPG?alt=media\&token=40822468-b092-4243-9c00-b30f8176ce15) ## Step 10. Glue the right blade in place using the hot melt glue * Same as before in Step 7.... * Heat the glue stick with a heat gun until the stick becomes soft * Dab the softened glue stick onto the end of the paddle shaft, dabbing glue at several locations * Using a stick/trowel, spread the glue over end of the shaft. You will have to apply heat to the deposited glue to allow it to be worked smooth. * Prepare to glue the blade onto the shaft by reheating the applied glue as well as pre-heating the blade socket. Take care not to overheat the shaft or the blade during this stage. * With the glue hot and the blade heated, assemble the blade onto the end of the shaft. Push the shaft all the way into the blade socket and then rotate the blade into the position where the alignment marks match up. * Remove any excess glue while it is still hot and easy to wipe away. * Let everything cool down. ## Step 11. Remove the masking tape * With both blades glued into place, remove the masking tape. If there is any excess glue around the joint, then a bit of heat and a rag with turpentine will clean everything up nicely. ## Step 12. Waterproof the blade join Corrosion is a natural enemy of any electronic product. Although fully-waterproofred, we want to limit the exposure of the internal surface of the load cell to salt water where at all possible. As One Giant Leap has no control over the quality of the hot melt glued bond that joins the blade to the shaft (as this task is performed by the end user), we recommended all customers to seal this joint with a combination of amalgamating tape and heat-shrink. Both the amalgamating tape and heat-shrink have been supplied with your Power Meter. * Peel the white backing from the amalgamating tape.

The output of a load cell when the shaft is experiencing no force is referred to as the **Zero Offset**. Each load cell has an associated zero offset. There are six load cells on a kayak power meter, 3 in the left shaft and 3 in the right. The load cells have been designated **A**, **B,** **C** for each shaft The **Zero Offset** of a load cell can drift a small amount with a change in temperature. This is why manufacturers of power meters typically recommend performing a Zero Offset calibration on a semi-regular basis. The **Zero Offset** of a load cell will be between -2047 and 2047. A typical **Zero Offset** will change no more than 2-5 units between calibrations. A difference of 10 or more is an indication that either a bending force is being applied to the shaft; that there is an issue with that particular channel or that you recently travel from an extremely hot or cold climate. {% hint style="info" %} After performing a number of Zero Offset calibrations, it will quickly become clear how frequently or infrequently a Zero Offset calibration is required. If the Zero Offsets vary by no more than **two** between calibrations, then there is little to be gained from performing a calibration regularly. {% endhint %} # Zero Offset calibration ## Step 1. Navigate to the [Calibration](https://app.onegiantleap.co.nz/calibration) page of the Web Bluetooth app and connect to the power meter ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1S8dGPVEYo4H11XbmA%2F-M1SBvadDEu3bPn4YeTD%2Fimage.png?alt=media\&token=e22a5f1f-7e14-458d-8150-c39e5dd4ebe2) ## Step 2. Perform the Zero Offset Calibration * Make sure that the Power Meter is not experiencing any force when you perform the 'ZO' calibration. It's best practice to stand the paddle vertically by leaning it against a wall. This ensures that the shaft is experiencing as little bending as possible. * Click on "Zero Offset" for both the Left Shaft and the Right Shaft. The Zero Offsets will update automatically. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1S8dGPVEYo4H11XbmA%2F-M1SDCt2eQQA3aeh87DM%2Fimage.png?alt=media\&token=18fb4f36-4646-4986-b0c8-bb0e1cd1078e) # Scale Factor A Scale Factor Calibration can be performed using basic and easily sourced components, or with a specifically designed calibration jig available for purchase from One Giant Leap. There is also the option to have the calibration jig manufactured yourself; the profile cut part files and assembly instructions are available here to download. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1RrRpHEgCplzwgRxMK%2F-M1RzWgzMq-okNnT3GaC%2Fimage.png?alt=media\&token=7c2d929b-c11e-4522-941a-66fc16c19ea5) ## Setup The calibration process requires the paddle to be setup in the following way: * Paddle shaft horizontal * Paddle assembled with the offset angle set to 90degrees **Right Hand Twist** * Supports located at the approximate blade centre and top hand positions * Calibration weights (with known weight) hung from the approximate bottom hand position ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LX1KxwqB6fAAyTdU0s-%2F-LX1LMRpHjQzCdLkszi8%2Fimage.png?alt=media\&token=75f8354d-1bc4-4737-9a80-fbfcec961dac) ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1RrRpHEgCplzwgRxMK%2F-M1Rxz0ZV7x2Ezd041-l%2Fimage.png?alt=media\&token=91c3697a-183e-417d-94ed-557541022e46) The supports can be as simple as blocks of wood resting on two separate tables. The space between the two tables is where the calibration weights will hang. Ideally the supports will have narrow width so that the paddle is supported at a definite spot which can be identified and measured. The calibration weight can be applied by suspending them from the shaft with a rope. The calibration process requires the strain output to be recorded with at least 2 different calibration weights (heaviest weight at least 20kg). The values are then input into the calibration spreadsheet where the scale factors are calculated. The right and left shafts of a kayak power meter are calibrated separately, so the process must be carried out on the right shaft and then repeated for the left. # Blades-on Scale Factor Calibration {% hint style="danger" %} These directions require that you have already assembled, charged, and configured your power meter shaft. All necessary steps are covered in the [Getting Started](/2.1/kayak/getting-started) section. {% endhint %} ## 1. Place the paddle onto the calibration jig * Place the paddle onto the calibration jig, note if the left or right shaft is being calibrated. * The blade should be supported near its centre. * The shaft support should be approximately at the top hand position. ## 2. Measure distances and weights for calibration {% hint style="info" %} We recommend all lengths are recorded using millimetres, and weights using kilograms. {% endhint %} 1. **tipToDatum:** The distance from the blade tip to the datum of the shaft being calibrated. 2. **weight1, weight2:** The weight is measured in kilograms.

Record the weight 1 values Attach the first set of weights (**weight1**) at the location designated in your earlier measurements. The first thing you should notice is a slight increase in the **Output** row values. To record these values we just click the **weight1 value** on the left side of the fifth row from the top(yellow).

Check the values and remove the weights Double check that all the weight values have been stored properly in the **Zero weight, weight1,** and **weight2** rows. Then go ahead and remove any weights that are still attached. ## 9. Update the Scale Factor values Now that you have all the values necessary for calibration, you'll need to update the scale factor. First, last check all the numbers look right. The **R**² row, fourth from the bottom (orange), should show the value of **1** for the **A**, **B**, and **C** columns. If everything looks good, click the **Scale F.** (yellow) text on the left side of the fifth row from the bottom.

Measure and enter datum distances Remove the paddle from the jig and without altering the length of the paddle, measure the datum distances and enter these into the calibration spreadsheet. * **Tip to datum:** The distance from the right blade tip to the right shaft datum mark * **Datum to datum**: The distance between the datum mark on the right shaft and the datum mark on the left shaft. If you find it difficult to measure this distance, you will find it easier with the paddle set to the same length, but with a 0° offset ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1RrRpHEgCplzwgRxMK%2F-M1S4fCS3NJV7HOLtEr3%2Fimage.png?alt=media\&token=0e895a3b-2d80-442d-b860-f8f4c610cfec) ## Step 7. Enter the datum to Gage distances Enter the Datum to Gage distances into the spreadsheet * Tip to Blade Gage = 0.28m * Tip to Centre Gage = 0.1m * Tip to Extra Gage = 0.06m {% hint style="info" %} Note that some Whitewater Slalom shafts have custom Datum to Gage distances. If you have a Whitewater Slalom Kayak Power Meter, please get in touch with One Giant Leap to get confirmation of your Datum to Gage distances. {% endhint %} ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1RrRpHEgCplzwgRxMK%2F-M1S5RTZf6PRRR1kn4As%2Fimage.png?alt=media\&token=aba4f795-b9aa-4ecf-b972-50aafde93c00) ## Step 8. Calibrate the left shaft Place the paddle onto the calibration jig with the left blade on the blade support and **repeat steps 1 to 7**, this time completing the ‘Left Shaft’ section of the spreadsheet. ## Step 9. Retrieve the Scale Factors from the spreadsheet * The Scale Factors for each channel are shown in the plots of the calibration spreadsheet (see example below): ![e.g. y = 0.1747x indicates the Scale Factor is 0.175](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LAGTXbZDPbd6IQXnJss%2F-LAGTw3d8zC_rfF1oS48%2Fimage.png?alt=media\&token=b610bb44-d1aa-461a-94ae-fe29d2a49436) Note that the C channel scale factor of the *left shaft* is shown alongside the A and B channel scale factors of the *right shaft*. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1RrRpHEgCplzwgRxMK%2F-M1S6ss3amKFiV9HgNjy%2Fimage.png?alt=media\&token=ff2a4591-4421-4ce4-89c5-1d03e78261dc) {% hint style="info" %} The R^2 value should be close to 1. This indicates a good calibration. {% endhint %} ## Step 10. Set the Scale Factors * Navigate to the [Calibration](https://app.onegiantleap.co.nz/calibration) page of the Web Bluetooth app and connect to the power meter * Open the Web Bluetooth App, connect to the Power Meter and navigate to the calibration page * Set the scale factors by clicking on the scale factors and enter the values. The Scale Factors should be multiplied by 1000 before being entered into the app. For example, if the Scale Factor is 0.1747, then the value '175' should be entered into the app. This value has been rounded up to **three** significant figures and does not include any decimal places ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1RrRpHEgCplzwgRxMK%2F-M1S7xuSA8S0A8HSzEJa%2Fimage.png?alt=media\&token=a104457e-cbbd-4c26-87d4-c295cf895827) ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1SHoJn0ESUGBo3-gI3%2F-M1SIAdjStNddP50PAEb%2Fimage.png?alt=media\&token=6c9b1b79-c044-463f-8b6b-528141d8fbb9) # Advanced # Adjust your clamp You can increase or decrease the clamp tightness by adjusting the screws on the clamp mechanism: ## Step 1. Tighten or loosen the clamp screw * Use a Phillips-head screwdriver. Clockwise will tighten the clamp, counterclockwise will loosen the clamp. If it requires more than a gentle force to lock the clamp with the left shaft in, it is probably too tight and should be loosened. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0kfE-xWxXfuD6yAQk-%2FIMG_0832.jpg?alt=media\&token=d1e31786-fac3-4b46-b174-2be78ac00c70) # Remove and attach your sleeve The following instructions explain how to remove and install the clamp sleeve. A clamp sleeve of a different length can be fitted to lengthen or shorten the shaft. ## Step 1. Remove the existing sleeve * The sleeve is fitted to the shaft with hot-melt glue. Using a heat gun, heat up the glued end of the sleeve. The glued section is 75mm long. Take care not to overheat the shaft by heating gradually and frequently checking to see if the glue connection can be separated. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0khdB5-J4Bc2GN-8UJ%2F75mm.png?alt=media\&token=21ec0810-61cc-4b94-9140-e1b12e3db034) ## Step 2. Apply masking tape to the shaft * Allow a 35mm spacing between the end of the shaft and the edge of the tape. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0khkVHJHi9pP573Ra9%2F35mm.png?alt=media\&token=2b69afe4-59dc-4b42-a310-408f638109fe) ## Step 3. Apply tape to the end of the clamp sleeve ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0khqqfH5Hx956EuqCC%2FIMG_0839.jpg?alt=media\&token=3bd21f43-784f-4678-acf9-01c3f60ea569) ## Step 4. Apply hot-melt glue to the spigot section of the shaft * Heat and spread evenly. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LVeLrkhjACJE8HqOpmG%2F-LVeMrIbsQ9NxPkFxsSY%2Fimage.png?alt=media\&token=4f43211f-150e-4a6d-b3af-d54b9912eebf) ## Step 5. Heat up the glue on the shaft and pre-heat the clamp sleeve ## Step 6. Assemble the clamp sleeve onto the shaft * When the glue becomes melted and the clamp shaft warm, quickly assemble the clamp sleeve onto the shaft. Slide the clamp sleeve down the shaft until the bottom edge meets the tape applied in Step 2. Roughly align the “0 degree” marking on the clamp with the datum mark on the shaft. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0khzVcT-U5ccJFRQj_%2FIMG_0842.jpg?alt=media\&token=5f854397-dc7e-4063-bf45-6fcc3934f0eb) ## Step 7. Carefully assemble the left and right shafts of the power meter together * Clamp and set the offset angle to zero degrees. Take care as the hot-melt glue joint will still be hot and not yet set. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M0kaGI5zEIFcAyKuhFs%2F-M0kiCjgFo9Ef00zGJyM%2FIMG_0843.jpg?alt=media\&token=501b20a7-6c72-491a-82ea-03d4959e6822) ## Step 8. Using the Web Bluetooth app, rotate the hot-melt glue join until the 'Angle' values read the same on the L and R shaft * Hold the shaft approximately horizontal when doing this. * When the angle readings are equal, you have found the correct alignment of the sleeve. * If the hot melt glue join becomes difficult to rotate during this step, apply some heat with a heat gun to re-activate the glue. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LVeLrkhjACJE8HqOpmG%2F-LVeNigHqr9L1Mn3gF_q%2Fimage.png?alt=media\&token=b7862ab3-90e4-4faa-a4db-98227cba28d6) ## Step 9. Allow the hot melt glue to cool and set and then remove the masking tape * Applying the heat gun to any excess glue on top of the tape will allow the tape to be removed easily, removing the excess glue with it. * Any remaining excess hot melt glue can be rubbed away using Mineral Turpentine soaked rag. # Assemble, Charge and Configure Let's get that power meter sussed! # Assemble Putting it all together ## 1. Fit and attach the blade {% hint style="info" %} For this part of the assembly you will need the black hot-melt glue (included with your power meter), a popsicle stick, heat gun, power meter shaft, and your blade. {% endhint %} ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SNnU3oG9GBRlU0kIs%2Fdb-items-required1.png?alt=media\&token=92c22aa9-c17b-4596-adf8-253a415d7829) ### A. Identify the blade end of the shaft ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SO0LZxHG4Serrlrtj%2Fdb-blade-end.png?alt=media\&token=aef89e7e-3714-49d7-a2d0-bb07528e7103) ### B.

Attach and align the blade While the glue is warm and malleable, insert the blade spigot into the blade end of your power meter shaft. Align the blade and shaft using the LED light placement and the end of the blade. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SQf_-Z0LyIJOq0cHM%2Fdb-attach-align.png?alt=media\&token=f20e575d-b81f-4486-abd7-6b9d6fd551be) ### D. Clean up Any excess glue can easily be removed with a bit of direct heat and a swipe or two of a rag with turpentine. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SRF-tI27-cOQx1L2m%2FIMG_0800.JPG?alt=media\&token=1d7e2e90-b4e5-45e7-b7f5-1bd4ccb59c9d) ## 2. Fit and attach handle {% hint style="info" %} For this part of the assembly you'll need the black hot-melt glue stick, popsicle stick, heat gun, power meter shaft with attached blade, and your handle {% endhint %} ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SRm74G77nRGq08wP3%2Fdb-items-required2.png?alt=media\&token=e4336362-e9dc-4ff6-a27f-4ba05d5fb66f) ### A. Measure paddle length The depth that the handle spigot is inserted into the shaft dictates the length of the paddle. The adjustable range is 47" to 51" (1194mm to 1295mm). To set the paddle to lengths shorter than 47", the handle end of the paddle shaft and handle spigot must be cut. The rule of thumb is to cut equal amounts off both the handle spigot and handle end of the paddle shaft. e.g. to achieve 45" paddle length. Cut 2" off the end of the handle end of the paddle shaft, and 2" off the end of the handle spigot. Test fit the handle and shaft, setting the handle to the correct position to achieve the desired paddle length. Ensure that there is **at least 75mm** of handle spigot inserted into the shaft. Mark off the handle depth with a pencil so that you can see the correct depth when attaching the handle with hot-melt glue. ### B. Apply glue to handle spigot ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LXWvTncgxeIHZYmbtxJ%2F-LXWvvkRm0_jdV3kTK9p%2Fimage.png?alt=media\&token=87d4cd4a-7df0-482c-8dce-72e602f1217b) ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LXWvTncgxeIHZYmbtxJ%2F-LXWw-5PkWXUjIXxDZJY%2Fimage.png?alt=media\&token=df9f29ef-6e79-45bf-805b-829e8de74c22) ### C. Attach and align the handle The handle will be aligned so that it is parrallel with the end of the blade. Since we already aligned and attached the blade, this part is pretty easy. Make sure to insert the handle to the measured pencil marking we made in 2.A. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-SMlC-khNyvqjANh0F%2F-M-SUdL-o9gmgt-ai3hH%2Fdb-attach-align2.png?alt=media\&token=e28bb0b6-eb74-4e0c-a0ef-fbfffb806f11) ### D. Clean Up Same as before, a bit of heat and a rag with turpentine will quickly remove and excess glue.

We need to fill in the 'Blade tip to hand distances' and the 'Blade tip to datum distance' to properly configure your power meter for use. ## 2. Measuring blade tip to hand distances ### A. Measuring blade tip to top hand Place then end of the tape measure on the tip of the blade and measure to the top hand position. The top hand position is located in the mid-point of the handle grip. Write down the measurement, we'll input it in a bit. ![Top hand distance here is 1250 mm](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-X4HEOd-xWKEXKTfeA%2F-M-X9h82dBiXF0sAAcfD%2Ftop%20hand%20position.png?alt=media\&token=d2901c30-42cc-417b-b183-f298b3ce0e1c) ### B. Measuring blade tip to bottom hand Same as before, place the end of the tape measure on the tip of the blade and measure to the bottom hand position. The bottom hand position is located at the middle finger knuckle. Make a note of the measurement. ![Bottom hand distance here is 610 mm](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-X4HEOd-xWKEXKTfeA%2F-M-X9sfIkbyhxsb1PmgY%2Fbottom%20hand%20position.png?alt=media\&token=3642a40b-eb91-49b3-901e-2a4a027f0682) {% hint style="success" %} To make sure the power meter operates with consistent accuracy, it is important that your bottom hand location does not deviate from your bottom hand measurement. It is highly recommended to tape the shaft at the location, similar to the image below {% endhint %} ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-LXWxFsNeIHMaEMm7JOF%2F-LXX66K9zxrqG5ANSAew%2Fimage.png?alt=media\&token=bfae2d2b-0131-435d-ab75-3af9227dacd1) ## 3. Measuring blade tip to datum distance Same as before, tape measure on the tip of the blade and measure to the datum. The datum on a dragon boat shaft is located where the shaft attached to the blade ends, as shown below. ![datum distance here is 820 mm](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M-X-hB32eMnyDLi46vq%2F-M-X3TxvRbNM_ILlBbZd%2Fdatum.png?alt=media\&token=d592daa4-1772-45ae-8a18-6cdea77c82d1) ## 4.

Zero Offset The output of a load cell when the shaft is experiencing no force is referred to as the **Zero Offset**. Each load cell has an associated zero offset. The **Zero Offset** of a load cell can drift a small amount with a change in temperature. This is why manufacturers of power meters typically recommend performing a Zero Offset calibration on a semi-regular basis. The **Zero Offset** of a load cell will be between -2047 and 2047. A typical **Zero Offset** will change no more than 2-5 units between calibrations.

It should only take about 3-5 seconds for the charger to wake up your power meter. # Getting Started # How to assemble a high-kneel canoe power meter To assemble the power meter you need to attach blade and the clamp sleeve to the shaft. This guide describes the process of fixing the blade and sleeve into the correct position using the hot-melt glue included with your power meter. {% hint style="danger" %} It is **very important** that the blades are aligned with the zero angle of the shaft. Please read these instructions thoroughly. {% endhint %} {% hint style="danger" %} It is **very important** that the shaft is shortened by cutting the **sleeve** only. Do not cut the blade end of the shaft. {% endhint %} ## Step 1. Identify the components ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1Xjcj04wOj3y9S5Brh%2F-M1YAUGSRQdyFOXboSNi%2Fhkc-parts.png?alt=media\&token=557e5af3-c3c4-4068-9771-d850c4ebfc1f) ## Step 2. Assemble the shaft and slide on the blade (without applying glue) * Slide the handle into the clamp end of the sleeve, make sure to line up the engraved numbers on the handle with the zero degree mark on the sleeve clamp. * Slide the sleeve onto the spigot end of the shaft. Make sure to leave 35mm of exposed spigot (see image below) * Slide the blade into the end of the shaft. ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1Xjcj04wOj3y9S5Brh%2F-M1YCZF6ZZUSRhhWWtPU%2Fhkc-35mm.png?alt=media\&token=2a2dc6b4-a839-4111-b85f-a4d9ed40da5c) ## Step 3. Measure the paddle length and calculate how much to trim (this step only required for untrimmed shafts) * Measure the length of the paddle from tip to handle. * Calculate the amount that needs to be trimmed off the paddle by subtracting your desired paddle length (minimum) from the measured length. * Dis-assemble the shaft components. ## Step 4. Cut the sleeve (only required for untrimmed shafts) * Measure and mark onto the end of the sleeve the amount that needs to be trimmed off the paddle (see image below). {% hint style="warning" %} **It would pay to double check your measurements at this point.** {% endhint %} ![](https://2711382635-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LAFl-quJvXSIV-V8Y2Z%2F-M1Xjcj04wOj3y9S5Brh%2F-M1YDi_G_unEvW5vjY4i%2Fhkc-sleevecut.png?alt=media\&token=67094287-b0fd-4283-948b-4cc1273bf17e) * Cut the sleeve with a fine tooth hacksaw or a thin cut-off disc.

Setting up an Activity profile for Kayak/Canoe/SUP will mean that you can have device setting tailored for each activity and it's quick and easy to switch between the profiles. \ The standard profiles are ROAD, INDOOR and MOUNTAIN.\ Follow the steps below to setup a profile called Kayak/Canoe/SUP * Enter the settings menu (the three horizontal lines at the bottom left of the home-screen). * Select 'Activity Profiles'. * Select 'Create New' (bottom of the screen). * Select 'copy existing'. * Select 'ROAD'. * Use the touch-keyboard to name the new profile eg: 'KAYAK' or 'SUP'. * Select any of the options as the Default Ride Type. If you choose 'gravel' for example, uploaded activity data captured with the Kayak/Canoe/SUP profile will be titled in Garmin connect as a 'Gravel Ride'. * Customise the profile settings by following the on-screen directions, then Select 'Apply Profile' (top of screen). Now the new Activity Profile is set up. Swiping across the home-screen will allow you to switch between the Profiles. ## Step 3. Add the Power Meter as a 'Sensor' * Enter the settings menu (the three horizontal lines at the bottom left of the home-screen). * Select 'Sensors'. * Select 'Add sensor' . * Wake up the Power Meter by shaking (the LED's will begin to flash). * Select 'Power'. * The unit will perform a search and then locate your Power Meter.
