Wiring method

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.

Voltage qualification rate and voltage loss recording function

Prevent users from illegally removing or cutting off voltage connections.

• Open lid recording function

Prevent illegal changes to the circuit.

• Loss of current and phase failure recording function

Prevent users from illegally short circuiting current connections.

• Current imbalance record

Be alert to users intercepting electricity at the front end of the meter wiring.

• Power down recording function

Prevent users from illegally removing the working power supply of the electricity meter.

Reverse sequence alarm

If the user illegally connects the wires, the electricity meter will continue to alarm unless the wires are connected correctly.

If the above situation occurs, the electricity meter will display an alarm sign and record the start and end time of electricity theft.

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.

Power outage meter reading: Equipped with a power outage meter reading battery to provide the energy required for the operation of the energy meter, in order to maintain the relevant data in the meter.

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.
