GF333 Multi-function three phase Standard Meter with high stability

(Accuracy class 0.02%/0.05%)


GF333 can be used as a calibration device standard meter, also as a testing calibrator in measurement test center of grid corporation, power company and measurement department in power plant, national levels of measurement mechanism, quality inspection departments, research institutes, tertiary institutions, industrial and mining enterprises, electric energy meter and electrical instrument production enterprises etc.


Functions and Features

1. Measure the AC voltage, current, active power, reactive power, frequency, phase angle and power factor etc;

2. Measure the AC voltage, current 2~31 harmonic content and waveform distortion degree;

3. Measure active power energy error, reactive power energy error, the maximum output pulse frequency is to 2 MHZ;

4. Measure calibration device of voltage, current, power stability;

5. Measure calibration device the standard deviation of estimate;

6. Measure the voltage of the calibration device three-phase symmetric degrees, the current of three three-phase symmetric degree;

7. Measure calibration device of the magnetic induction;

8. Measure DC voltage and DC current;

9. Transducer measurement;

10. With RS232 interface, it can be controlled by PC operation;

11. Core part uses the 32 bit DSP and16 bit low power and high speed DAC consists of high accuracy AC collector.

12. Using 6.5 inch TFT color LCD screen, character display clear chart. Have the advantages of wide measuring range, high precision, stable and reliable operation, simple operation etc.
