4Single-phase electric meterWorking principle
The electricity consumed by the user is sampled through the signals on the voltage divider and splitter, and sent to the amplifier and multiplication circuit. The product signal is integrated and V/F converted, and then output through the frequency divider circuit to drive the stepper meter to accumulate electricity. The electricity consumption rate is displayed through the electricity indicator light.

5Single-phase electric meterInstallment and use
1. The electric energy meter can be installed and used after passing the inspection and being sealed with lead before leaving the factory
2. The electric energy meter can be installed indoors or outdoors, and the bottom plate of the meter should be fixed on a sturdy and fire-resistant wall. It is recommended to install it at a height of about 1.8 meters, and there should be no corrosive gases in the air
3. The electric energy meter should be wired according to the wiring diagram on the junction box of the electric energy meter, preferably using copper wire ends for connection
