Checking The Zero Point; Calibrating In Power Meter Mode - Pioneer SGY-PM910H User Manual

• This product has a correction function
for the zero point fluctuation caused by
varying temperatures.
The accuracy of this function improves
by calibrating the sensor when there
is a difference in temperature of more
than 4°C.
This function cannot measure correctly
if you calibrate the sensor before it is
acclimated to the outside temperature.
The sensor requires more than 20
minutes to become acclimated.

Checking the Zero Point

1.
Position the crank arm so it is
perpendicular to the ground,
pointing downward.
2.
Tap [Pedaling Monitor R] in
the sensor list screen of the
SGX-CA500.
3.
Confirm the value in [Force
Preview].
Make sure that the [Tangential
Direction Force] and [Radial Direction
Force] values are as shown here.
• Tangential Direction Force: 0 ± 3 N
• Radial Direction Force: 0 ± 3 N
Calibration of the right side is
finished. Calibrate the left side in the
same way.

Calibrating in Power Meter Mode

When calibrating the sensors in power
meter mode, position the crank arm
so it is perpendicular to the ground, do
the procedure to the left and right sides
together. Refer to the User's Manual of
the Cyclocomputer you are using for
details.
