Specifications
GF312V2 is light weight and compact high precision reference meter for on-site verification and calibration of single or three phase energy meters. Test voltage and test current for the
reference meter will be measured at mains on-site or can be generated and measured via external source (optional - model GF3031). 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. The model
GF312V2 portable electric meter calibrator is suit for electric power departments, metrology and quality examining departments and electrical lab to field use. YOU CAN ALSO LOOK IT
