Failure: Due to a malfunction in the instrument, a failure message is
outputted. This status message is always activated and cannot be
deactivated.
Function check: The instrument is in operation, the measured value is
temporarily invalid (for example during simulation). This status
message is always activated and cannot be deactivated by the user.
Out of specification: The measured value is unstable because the
instrument specification is exceeded (e.g. electronics temperature).
This status message is always inactive and can be activated via DTM
and EDD. The error codes and text messages are dispayed via the
indicating and adjustment module as well as DTM and EDD in the
control system. Additional information on error statstics is displayed in
the menu Diagnosis under "Device status" in the indicating and
