GF302C Portable Three-Phase AC/DC Indicating Instrument Test Equipment

(Accuracy class 0.05/0.1)

Application

It is suitable for power plant and substation work area of grid companies, make try department and the instrument classes, and
national levels measuring and testing institutions, railway, petroleum, chemical industry and other large industrial and mining
enterprises, scientific research units, etc.

Introduction

This device is according to nation verification regulation JJG124-2005 "ammeter, voltmeter, power meter and resistance meter
calibration regulations and the relevant countries standard requirements and design three-phase 0.05 magnitude meter source
integration calibration device. The core technology of the function of device with digital signal processor (DSP) and 16 high-speed
digital converter composed of high precision work frequency communication terminal; The signal source of use is DSP and 16
high-speed digital-to-analog converters can control of the sine wave, distortion wave signal source; Equipment has high precision,
stable and reliable, and convenient operation, flexible, and other characteristics; Electric power system is used for electrical
measurement is the ideal equipment calibration.
