Care instructions
Clean plastic surfaces with a damp cloth only.
Do not use any scouring or aggressive cleaning
agents! The device is maintenance-free during
the service life.
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.
