| Main technical parameters: 1. Input voltage: 220V 45~65Hz 2. Switch of the selection of current measuring range: Divided into 11 stalls, each stall difference between output current is 1 time, we can choose a suitable stall by tested meter. (propose to use the sixth stall which is 5A) Power factor: 0.5(C)-0.89(C)-1.0-0.8(L)-0.5(L) 3. Output current waveform distortion: <2% 4. Accuracy level of monitoring voltage, current meter(digital displayed): 1.0(or 0.5) 5. Accuracy of test bench: 0.2, 0.3(the level of standard meter: 0.1, 0.2). The testing total error wonnot exceed the national standard JJG597-89, which is shown in attached table 1. 6. Stability of output voltage, current and power: <0.5%(PF=1, 3min)(equipped with high-accuracy voltage-stabilized source).
