9.4.5 Calibration error
In each device predefined ranges for the calibration values are stored. If the determined calibration value is out of
the range the message
!Out of limit!
appears in the calibration information CAL INFORMATION. The deter-
mined calibration value will be stored nevertheless, so that the measuring and controlling is secured. As the case
a new calibration or a replace of the sensor is necessary.
