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!
