Anti theft function

If a user illegally removes or cuts off voltage or current connections, the electricity meter will issue an alarm signal until the user resumes normal electricity use.

• Open lid recording function

Prevent illegal changes to the circuit.

Lead sealed anti-theft function

Lead seals cannot be restored after one-time use.

Conventional display content of LCD screen

• The meter can be viewed to measure the forward and reverse active power and the phase separated power of A, B, and C.

• Can support viewing the active power consumption of the past 12 months.

• Total, A, B, C electrical parameters: phase failure, phase reversal, total reset, and timing event recording functions, as well as phase failure, phase reversal, and reverse phase sequence alarm prompt functions.

Meter reading method

• Display meter reading: By pressing the buttons on the meter, the monthly total electricity, voltage, current, power factor, and other data of the meter can be queried on the LCD screen.

Communication meter reading: Through RS485 communication port meter reading and handheld infrared meter reading machine, combined with meter reading system, various electricity data of the meter can be read. And supports DL/T645-1997 multifunctional energy meter communication protocol.
