Function and features:1.multi-purpose:
On-line measure the error of watt-hour meter and constant;
measure the CT ratio,combined error of watt-hour Meter and CT.
2.Real-time measurement :
measure the voltage, current phase Angle, frequency, power, power factor and other electrical parameters
3.measure the harmonic content within 30 times
4.Display voltage and current vector graphics, voltage and current waveform
5.convenient to provide three levels of built-in virtual load of 0.5A, 2.5A and 5A.
In the case of zero or close to zero real load, the keyboard switch is convenient for on-site verification to control the
virtual current output.
It is easy to operate and use the virtual current provided by the instrument alone to verify the error of the electricity
meter without clamping the meter, and the wiring is simpler and more accurate
6.Can store 1000 test data:
test data can be transferred to the computer, according to the need can be connected with
the power supply company's management system, convenient data management and report printing
