Depending on the anticipated effects, the messages on the two system components are
categorized into error messages and warning messages:
• Warning messages are generated if the measurement results are not (yet) directly af-
fected by the change in the system state. Nevertheless, it is important that the cause(s)
be investigated and corrected, e.g. by means of maintenance measures, to avoid further
malfunctions and damage to the device in particular.
• Malfunction messages are generated when measuring operation is no longer possible
or permitted.
These warning and error messages are stored in the integrated message memory of the
evaluation unit.
Messages on the evaluation unit
