23ENPairing and CalibratingCalibrating the Zero PointThis section describes how to use the Cyclocomputer SGX-CA500 to calibrate the zero point of the pedaling monitor sensor thatis installed on the bicycle. Zero point calibration is a function to store the zero point (no-load), where no forces act on the crank,in the sensor memory.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.Please do not push the push switch in the right transmitter while calibrating the sensor or showing [Force Preview] with the•Cyclocomputer SGX-CA500.1 Mount the bicycle on a trainer or some other safe stand.2 Position the crank arm so it is perpendicular to the ground, pointing downward.3 In the sensor screen of the SGX-CA500, tap [Pedaling Monitor R] and then [Calibration (Zero)] in order.4 Tap [Start Calibration].The calibration starts.If the calibration is successful, “Success” appears in the [Result] field.If “Failure” is displayed, the sensor may be calibrated in unstable condition that the crank is moving. Calibrate again with thecrank stopped.This product has a correction function for the zero point fluctuation 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 thesensor before it is acclimated to the outside temperature.The right side pedaling monitor sensor calibration is finished. Calibrate the left side in the same way.After finishing the calibration of the pedaling monitor sensors on both sides, check the calibration (page 24).Calibration
