For configuration we need your fully charged power meter, a computer or mobile device with bluetooth capabilities, and a tape measure.
Measurements are recorded and entered using Millimeters
Make sure your power meter is on and connect via our OGL app
Everything should look pretty similar to the screenshot above. 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.
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.
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.
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
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.
click on the 'Blade tip to hand distances field and enter you measurements.
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. 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.
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.
To do an offset, click on the hamburger menu in the upper left hand and select 'Calibration'
On the right side of the screen, click on the box that says 'Zero Offset' to perform a zero offset calibration.
