─ Single- and three-phase electronic meters with built-in DLC
modem, GSM/GPRS modem or RS485 comm. interface
components and manufacturing procedures ensure
high long-term stability of meters, so that there is no
need for their recalibration during their life.
10. Anti-fraud protection
The meter cover and the meter terminal cover are
sealed by means of sealing screws and conventional
wire seals. Unless the seals are broken, the access
into the meter enclosure is not possible.
On customer’s demand the meter can be equipped
with special internal switches for the detection of any
lifting of the meter cover or meter terminal cover.
