Calibra Tion Zeroing; Rotor Inspider Training Use - ROTOR INspider ROT117 User Manual

4. CALIBRA TION ZEROING /
The main reason to calibrate/zero your power meter is to ensure an exact power measurement.
Calibrating the power meter compensates for any mechanical change that influences
measurement since the last calibration/zeroing. You should therefore calibrate your ROTOR
spider power meter after assembling your bike with all its accessories, including pedals.
ROTOR power meters require a second calibration to calibrate the angle. It is necessary to
strictly follow all the steps described in the following section to ensure an accurate power and
cadence measurement and TORQUE 360 and OCA representation.
There's no need to calibrate/zero your ROTOR INspider every time you use your bike, but it is
convenient to zero it once a week approximately. It should always be done when installing the
system on the bike for the first time, or when assembling or swapping chainrings. To perform
another calibration after the first 30 hours of use is recommended too.
The detailed calibration process is described in section 4.1. Complete the entire calibration
process step by step to ensure correct power and cadence measurement.
