JW-0305 Single-phase AC,DC Meter Calibration Device

1. The device iscomposed of single-phase AC standard voltage source and standard current sourceas well as DC standard voltage source and standard current source which enableoutput.

2. It hascalibration function, i.e. it can correct the output value of standard sourcesaccording to indicated values of external standards.

3. It can checkmanually and self-automatically in power system all kinds of single-phase ACpower frequency indicators such as voltmeters, ampere meters, wattmeters,frequency meter and each type of DC meters which are not above class 0.2.

4. It can generateharmonic wave with 2~31 order, and it is can be program-controlled that thequantity and times of the harmonic wave, and the phase angle of the harmonicwave vs. fundamental wave.

5. There are USB interfaceand RS-232 interface. It can implement automatic verification by controlling ofthis device using PC via upper-computer software, and it will process andmanage the results.
