Important
When Sensor Head calibration fails
If the Sensor Head is calibrated in an inappropriate environment, an error is displayed on the main display. If this
happens, chack the environment and try again. If an error continues even after calibrating the Sensor Head in an
appropriate environment, the fiber connector on the Sensor Head or Sensor Controller may be stained. Clean the fiber
cable or fiber connector referring to p.39.
Note
Calibrating Sensor Head can also be set by the operating keys on the Sensor Controller.
