GF312V2 portable three phase multifunction watt-hour meter calibrator on-site is the newest product produced by our company by widely visiting users and referring to the advantages of the same kind of products home and abroad. The measured part of the product adopts high speed A/D transmission to send DSP to conduct digital processing, which largely improves measured degree of accuracy and stability. Central processing part adopts 32-bit ARM embedded technology to make instrument interface novel, function abundant, operation distinct and easy, and performance steady. Class of accuracy: Class 0.02, 0.05 or 0.1, range from 12A/600V or 120A/600V, with comfort design, small size and light weight. The model GF312V2 watt-hour meter calibrator is suit for electric power departments, measuring and quality examining departments and electric lab to field use.
High voltage insulation megohmmeter is composed of medium and large scale integrated circuits. This meter has large output power high short-circuit current value and large output voltage grades (there are four voltage grades). The working principle is as follows: the DC high voltage generated by the battery inside the machine as power supply and converted by DC/DC reaches the L pole from the E pole by the tested product so as to generate a current from E to L pole. After I/V conversion and operation by the divider the measured insulation resistance value is directly displayed by LCD.
