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.

Error codes show faults detected by multidata. If more than one error appears, the sum of the error 
codes is displayed: Error 1005 = error 1000 and error 5.
