Calibrate (zero offset) your power meter using your display unit before riding. For optimal performance, allow the power meters to adjust to the ambient riding temperature before performing a zero offset. This normally takes just a few minutes.
1. Connect to your power meter, and navigate to the DEVICE page.
2. Spin the crank arms 3-4 times to wake up the power meter. Place your crank arms in the 12 and 6 o’clock positions, with the non-drive side crank arm downwards.
3. Press on the ZERO OFFSET or CALIBRATE icon, then tap the image of the crank to begin the calibration process.
Tip: If you receive an error message, check that the bike is stable and upright and the cranks are in the correct position before trying again.
