GF302D 120A 600V Portable three phase energy meter test board with 0.04% accuracy Internal 3 Phase Standard
The GF302D portable three phase energy meter test board consists of an integrated three phase 120A current source and 600V voltage source and a class 0.04 three phase electronic reference standard meter.
The energy meter test board is particularly designed for analysis of complete metering installations and local mains conditions. The meter test bench offers high functionality combined with an excellent menu guided operation via built-in thirty keys and colored 7" touch LCD-display.
GF302D is completely programmable with features such as imbalanced loads which can be programmed to modify the voltage and current on each phase, repetitive testing where you can test the same meter an unlimited number of times. The user can change any variable such as voltage, current, Ke, frequency number of revolutions, etc all with their finger.
GF302D meter test board uses a specially designed Sentry GF12 Optical port for testing meters through the optical port. The Sentry GF12 can also be used for programing and resetting the meter by toggling to the manufacturers software. Both testing and programming/resetting can be accomplished without changing probes.
