Calibration; Calibrating A Highly Precise Zero Point - Pioneer SGY-PM900H90 Installation Manual

Calibration

This section describes calibrating (calibrating for the zero point for higher precision) while there is a load on the pedals and while
there is no load on the pedals.
It is necessary to calibrate the sensors on both the left and right sides. The right-side pedaling monitor sensor is used as an
example in this description. The procedure to calibrate the left side is the same as for the right side.
• Calibrate the pedals under load within 5 minutes after calibrating a high accuracy zero point. Recalculate the high accuracy zero point
again if more than 5 minutes elapses.

Calibrating a Highly Precise Zero Point

1
Remove the left and right pedals from the crank arms.
2
Screw the calibration pedal bolt into the pedal hole on the right (R) side crank arm about 10 mm.
•
Screw it into the left (L) side to calibrate the left side.
•
"R" and "L" are engraved on the ends of the bolts for calibrating.
3
Hang the calibration weight onto the outer groove of the calibration pedal bolt.
