Stability criteria
You define the permitted variation in the
measured value which may not be exceeded in a
certain timeframe during calibration. If the
permitted difference is exceeded, the calibration
will not be allowed and is canceled
automatically.

The function checks whether the calibration of a
sensor is still valid. Example: you install a pre-

ago the sensor was last calibrated. A diagnostic
message is displayed if the last calibration is
longer in the past than the prespecified warning
or alarm limit.
