Status display / Error codes
The symbols in the table below show the meter’s operational status. The
status messages only appear in the main display (energy). The temporary
display of the warning triangle can be caused by special operating states
and does not always mean that the device is malfunctioning. However,
should the symbol be displayed over a longer period of time, you should
contact the service company!
