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
