4.Frequency: 50/60Hz

5.Starting current: 0.04Ib(1.0S), 0.05Ib(2.0S)

1).Measure active electric energy,do not need calibrate for long-term operation;
2).Adopt the special chip of measurennentADE7755;
3).Adopt the latest oversea electric energy special integration circuit,greatly improved dynamic working range of Meter, making the ability of actual overload up to over10 times;
4).Have hood mistake linearity in the range of 5% lb-Imax;
5).Few periphery components,simple structure,low power consumption;
6).Adopt high reliability and long life electronic components,so the Meter assume feature of high reliability and long life;
