EMT
EMT
Electricity meter EMT is electronic three-phase meter, which measures active energy and is approved according to IEC 62052-11 and IEC 62053-21. Meter is ideal for domestic users with its simple structure, reliability and transparency.

Measuring
Meter operates in three-phase electricity networks and independently from current flow direction measure:
- Active energy with accuracy class 1.0 or 2.0 (IEC 62053-21)
Outputs
- Electric pulse output (S0)
- LED test output for active energy
- Four status indicators (LEDS) - Ä, L1, L2, L3:

Display
EMT meter is equipped with traditional electromechanical drum-register. Register can be either 5+1 or 6+1 digits, which offers sharp readability when compared to electronic displays. The register offers the additional advantage of allowing the meter to be read when power is absent with no need to use power backup.Technical Specification:
