Functional feature diagram

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.
