Portable Energy Meter Tester To Test Three Phase / Single Phase Meters

KE7303 portable three phase standard meter is used for the test of three phase / single phase meters, electrical parameter of the power line, the transformer ratio by electric power companies, meter manufacturing companies and institutes of metrology.

Highlight: Calibrate the error of all electricity energy meters, checking the constant of the energy meter 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 in the same loop Measure voltage, current, frequency, power, power factor and phase angle Simultaneous measure and display waveforms of three phase voltage and current Detect the error change of the clamp automatically; ensure the accuracy stability of the clamp and the instrument in the long run. Measure ratio of CT, VA burden of the metering loop from VT and CT secondary terminals. Allocate clamp of 20A, 100A, 500A, 1000A to directly measure the comprehensive error Measure the 2nd – 51st harmonics of current and voltage Display vector diagram, judge the wiring right or wrong automatically Read the information of energy meter with barcode scanner (optional) Battery, test lead power or external power for choices Communicate with PC, download calibration data through USB flash disk, RS-232 or bluetooth Firmware can be upgraded through removed disk by users themselves Save and browse the testing data ? ?
