Click [Execute sensor head calibration].
The sensor head calibration window appears.

With no object in the measuring range, or
with the tip of the sensor head shielded from
light by an object that has the characteris-
tics of diffusion reflection, click the [Execute
sensor head calibration] button.
Important
• 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 Sen-
sor Controller, or extending a fiber cable, be sure to calibrate the Sensor Head again.
• When Sensor Head calibration fails
When sensor head calibration is performed in an inappropriate environment or with an extension fiber cable set
incorrectly, an error message is displayed. In such a case, refer to the p.48, recheck your environment, and try
again. If an error results even if Sensor Head calibration is done under the correct conditions, it is possible that
some contaminants may have adhered to the Sensor Head part, or the fiber connector of the Sensor Controller.
Clean the fiber cable or fiber connector referring to p.70. After cleaning the fiber or fiber connector, be sure to
calibrate the Sensor Head again.
• Re-adjustment is obviously required when described
the following, warning message appears on the
Multi-view Explorer.
• When the Sensor head is not adjusted correctly.
• When the extender fiber cable is added.
• The maximum value of the measurement cycle will
differ depending on the extension fiber cable setting.
If sensor head calibration was successful and the
measurement cycle does not exceed the maximum
value, there will be no impact on measurement
accuracy even if the extension fiber cable setting is
incorrect.
