- Using LCD liquid crystal display to show electricity information, under normal use conditions, the service life of LCD liquid crystal display is over 10 years.
- With power pulse output for meter calibration, and passive photoelectric isolated OC gate output port, the pulse width is 80ms±20ms; The waveform is a square wave.(Optional)
- Using super bright, long life LED working indicator. The pulse indicator(red) flashes when there is a pulse.
- With UART interface communication method, it can be expanded to other communication methods.

- Measurement Function Measure total active power and store its data. With positive and negative active energy measurement function, accumulating negative active energy as positive energy.
- Display Function Cumulative total power, voltage, current and active power.Power display with two decimal places, with unit of kWh.Voltage display with one decimal places, with unit of V and represent as “U”.Current display with two decimal places, with unit of A and represent as “I”. Power display with two decimal places, with unit of kW and represent as “P”.
- LED indicator introduction Pulse indicator: pulse indicator(red) flashes when there is a pulse. On-off switch indicator:
