Functions and Features:
1. Measure three phase active electrical energy and neednt calibrate in the long lasting work status;
2. Separately measure the active energy of phase A, B, C;
3. Three phase power supply, 1 wire(any wire of 3 wire in 3 phase 3 wire meter) or 2 wires(any 2 wires of 4 wires in the 3 phase 4 wire meter) power cut, the electric meter can still work normally;
4. Can realize the infrared or RS485 communication through handheld computer or PC machine to finish programme setting and meters reading, can also finish the manpowers meter reading through infrared remote controller.
5. Use wide LCD display;
6. Voltage detection display function;
7. Have the electric energys testing output;
8.  Extended function:
    1). With built-in relay, and support the remote controlling of switch off / on;
    2). Prepayment functions switch.
