8.1 Error descriptions and countermeasure
The self check function displays instrument errors, warnings and alarms.
When an alarm or error occurs, the code (e.g. E-01) and the name (e.g. Frequency fault) appear on the
display during display mode, alternating with measuring value indication. This does not happen in parameter
setting mode.
The alarms, errors and warnings are written into history, see chapter 9.2.
The following table shows the possible alarms, warnings and error with the concerning influences on outputs
and fields variables.
