ZERO OFFSET USING YOUR DISPLAY UNIT
Zero offset (calibrate) 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. Unclip and dismount from your bike for the zero offset.
2. Spin the crank arms 3-4 times to wake your power meter.
3. Connect your power meter with your display unit.
4. Place your crank arms at 12 and 6 o’clock, with the non-drive side crank arm down.
Hold the bike stable and upright.
5. Use your display unit to calibrate your power meter.
- Navigate to the Zeroing or Calibration menu.
- Press “Zero” or “Calibrate”.
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.
