Save Function/Memory Function
Automatic Save Function: when the power is off, the meter will automatically save the current energy value, and the meter will read the value after the next power on, and continue to accumulate.
>>Use and Wiring Method
1.Connect the wires according to the wiring diagram in the attached drawing, and insert the two-wire plug of the secondary end of the current transformer of the instrument into the secondary input end of the instrument. Pass the main loop wire of the current test through the middle round hole of the current transformer.
2.Connect the voltage measuring lead to the measuring voltage input terminal of the meter. Then turn on the measurement voltage. St
