GF313V2 Power Engineering Device Three Phase Power Calibration

Product Description

Product Description

GF313V2 onsite portable three phase electronic meter test set 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 0.1, 0.2 or 0.5, range from 3×120A/3×600V or 3×200A/3×600V, with comfort design, small size and light weight. The model GF313V2 three phase meter meter test set is suit for metrological service of electricity power utilities, industrial and mining enterprises and electric lab to field use.
