Tampering Protection Function:
1 bypass power detection, record events and LED alarm.
2 open terminal cover detection, LCD alarm display and record the event.
3 record external magnetic field event.
4 record over voltage and low voltage event.
5 self-diagnostic: EEPROM check, battery alarm.
Total active energy power, voltage effective value, current effective value, average active energy on second, current date, current time.
- RS485 communication, used for remote reading, remote controlling and local reading.
- IR communication, used for local setting and reading.
- M-BUS communication, used for reading and controlling the water meter.
Over voltage, low voltage, bypass, current reverse, power off, open terminal cover.
Single phase active energy measurement, keep records of power, average active energy on second, voltage effective value, current effective value, demand.
