Calibrating Sensor Head - Omron ZW-XC7 User Manual

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 Sensor Controller (Including the initial connection).
• When extending a fiber cable.
• When "Dark" is shown in the main display even though a measurement object exists in the measurement
range.
• [Dark] is displayed on the main display even if the measurement object is within the measurement range.
The calibration data is stored inside the Sensor Controller. Therefore, if the sensor head is calibrated once, as
long as the fiber connection state does not change (if it is not disconnected from or connected to the Sensor
Controller or an extension added), this operation is not needed each time. After removing/inserting a fiber cable
from/to the Sensor Controller, or extending a fiber cable, be sure to calibrate the Sensor Head again.
The Sensor Head should be calibrated without any object 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 mirror.
• Without any object
