Calibrating Sensor Head
Calibrate the Sensor Head by obtaining the dark data in the no-incoming light status.

• When removing and inserting a fiber cable from/to the Controller.

The Sensor Head should be calibrated without any workpiece within the measuring range
or with the tip of the Sensor Head shielded from light with an object with diffuse reflection.
(Correct calibration is not possible with a transparent object, semi-transparent object, or
