Three-phase energy meter field calibrator

TT
More complete wrong wiring recognition functions, and IB access and reverse connection
of TV, TA polarity can be recognized;

TT
The instrument power is supplied with battery and test circuit, and can be online charged.
2.2 Main features

TT
Check the error of active and rewatt-hour meter at the same time, and meanwhile check
the error of main and secondary meter in the same circuit.

TT
Check the voltage, current, power, power factor, phase and frequency and other electrical
instruments and transmitters by contrast method.

TT
Identify 48 common three-phase three-wire, and 96 three-phase four-wire connection
errors in four quadrants, and show the hexagon diagram of any connection.

TT
Clip-on ammeter self-calibration function can guarantee the long-term accuracy stability of
clamp transformers. The self-test between any two phases ensures the long-term accuracy
stability of the instrument.

TT
to 51 three-phase voltage and current harmonics can be measured, and all harmonic data
can be stored.

TT
Display three voltage and current waveforms at the same time.

TT
Measure TV, TA secondary load.

TT
Store all measurement data of 6,000 meters, including operating parameters, to facilitate
subsequent analysis.
