GF112 portable single phase electric meter tester is with human oriented design, hand-held and lightweight. It is suit for electric power Metrological departments, measuring and quality examining departments and electric lab to field use. It is capable of testing various types single phase watt-hour meters on site and can also be used for testing alternating current parameters , for example U, I P, Q, S, F, E etc. It is one of ideal test tool for engineer testing single phase electricity meter accuracy. The portable reference meter can be used with an active error compensated clamp-on CT 100A (range from 10 mA to 120 A / cable diameter: max. 20 mm).
