Introduction
GF333 three phase multi-function standard meter, its core part uses the DSP 32 bit and16 bit low power and high speed DAC consists of high accuracy AC collector. Not only it can be used as a calibration device standard meter, but also it can be used as a testing calibrator. 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.
