The messages aredivided into the following categories:Failure: Due to a malfunction in the instrument, a failure message isoutputted. This status message is always activated and cannot bedeactivated.Function check: The instrument is in operation, the measured value istemporarily invalid (for example during simulation). This statusmessage is always activated and cannot be deactivated by the user.Out of specification: The measured value is unstable because theinstrument specification is exceeded (e.g. electronics temperature).This status message is always inactive and can be activated via DTMand EDD. The error codes and text messages are dispayed via theindicating and adjustment module as well as DTM and EDD in thecontrol system.
