Sensor Calibration
This feature allows the sensor to be calibrated. Ensure that the correct
sensor type is selected in the configuration prior to calibration. Refer to
section 4.8. for details of the menu system operation.
Note:
if the password is in operation then the user will be prompted with
PASS when ever the menu key is pressed. Pressing the MENU key
again will result in the restricted user access, i.e. only the zero and

give access to the full menu facility.
