Calibrating the Sensors
This section describes how to use the Cyclocomputer SGX-CA900 to calibrate
the zero point of the pedaling monitor sensor that is installed on the bicycle.
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.
Refer to the User’s Manual of the Cyclocomputer you are using for calibrating in the •
power meter mode.
Getting Ready
1.
Stop the bicycle on a at safe
place.
2.
Remove the pedal.
Remove the pedal to do the calibration.
Calibrating the Zero Point
1.
Position the crank arm so it is
perpendicular to the ground.
2.
Tap the [Sensors] icon in the
home screen of the SGX-
CA900.
The sensor list screen opens.
3.
Tap [Pedaling Monitor R] and
then [Calibration (Zero)].
4.
Tap [Start Calibration].
The calibration starts.
If the calibration is successful,
“Success” appears in the [Result] eld.
If “Failure” is displayed, the sensor may
be calibrated in an unstable condition
causing the crank to be moving during
the calibration. Calibrate again with the
crank stopped.
This product has a correction •
function for the zero point uctuation
caused by varying temperatures. The
accuracy of this function improves
when the sensor is calibrated in
different temperatures.
This function cannot measure
correctly if you calibrate or check the
sensor before it is acclimated to the
outside temperature.
