Product Description
Product Description
GF312D1 emesyst energy electricity kwh watt-hour meter calibration equipment portable
The GF312D1 emesyst energy electricity kwh watt-hour meter calibration equipment portable instrument is a precision AC energy meter testing instrument, mainly used to test three phase energy meter error on site and measure all various of AC parameters.
1. Three phase active or reactive electricity energy meter
2. Calibrate three phase, single phase, and active or reactive meter error
3. Measure U(voltage) of three phase or single phase
4. Measure I(current) of three phase or single phase
5. Measure active power of three phase or single phase
6. Measure reactive power of three phase or single phase
7. Measure apparent power of three phase or single phase
8. Measure power factor of three phase or single phase
9. Measure phase angle between voltage and current
10. Measure frequency of power line
11. Display vector diagram
12. Display waveform of U and I
13. Analyze and display content of harmonic of U and I
14. Measure 2-64 harmonic of U, I
15. Store and display measured data
16. Optional 5A, 20A, 100A, 500A, 1000A, 2000A, 3000A current clamp
17. Measure CT variable ratio
18. Measure the ratio or lag-angle of low-voltage transformer
19. Adopt 32 bit ARM processor, multi-channel 16 bit precision A/D convertor, high resolution TFT color LCD
