Highlight

²           Calibrate the error of all electricity energy meters, checking the constant of the energy meter

²        Simultaneous checking of the primary meter and the secondary meter in the same loop, or simultaneously checking of the active power meter and reactive power meter inthe same loop

²        Measure voltage, current, frequency, power, power factor and phase angle

²        Simultaneous measure and display waveforms of three phase voltage and current

²        Detectthe error change of the clamp automatically; ensure the accuracy stability ofthe clamp and the instrument in the long run.

²        Measureratio of CT, VA burden of the metering loop from VT and CT secondary terminals.

²        Allocate clamp of 20A, 100A, 500A, 1000A to directly measure the comprehensive error

²        Measurethe 2^nd – 51^st harmonics of current and voltage

²        Display vector diagram, judge the wiring right or wrong automatically

²        Read the information of energy meter with barcode scanner (optional)

²        Battery, test lead power or external power for choices

²        Communicate with PC, download calibration data through USB flash disk, RS-232 or bluetooth 

²        Firmware can be upgraded through removed disk by users themselves

²        Save and browse the testing data, data storage quantity is 1000 group
