KE7303
Portable Three Phase Standard Meter
Accuracy : 0.05 / 0.1, Test method : terminal input or clamp CT input, test the error of three phase energy meters and feild electrical parameters of power grid

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 2nd – 51st 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
