8.3 Asset Management function
The instrument features self-monitoring and
diagnostics according to NE 107 and VDI/
VDE 2650. In addition to the status messages
in the following tables there are more detailed
error messages available under the menu item
"
Diagnostics
" via app or PACTware/DTM.
Status messages
The status messages are divided into the
following categories:
•
Failure
•
Function check
•
Out of specification
•
Maintenance requirement

Abb. 31: Pictographs of the status messages
1 Failure - red
2 Out of specification - yellow
3 Function check - orange
4 Maintenance - blue
Failure:
Due to a malfunction in the instrument,
a fault message is output.
Function check:
The instrument is being
worked on, the measured value is temporarily
invalid (for example during simulation).
Out of specification:
The measured value is
unreliable because an instrument specification
was exceeded (e.g. electronics temperature).
Maintenance:
Due to external influences, the
instrument function is limited. The measurement
is affected, but the measured value is still valid.
Plan in maintenance for the instrument because
a failure is expected in the near future (e.g. due
to buildup).
Information:
The status messages are always active.
It cannot be deactivated by the user.
