INTRODUCTION The GF302D1 three phase portable energy meter test system consists of an integrated three phase current and voltage source(up to 500V/120A or 500V/20A) and built-in three-phase electronic reference standard of accuracy class 0.05%. Characteristic features of the GF302D1 are its wide measuring range, high accuracy and high tolerance to unwanted external influences. The equipment offers high functionality combined with an excellent menu guided operation via built-in keyboards and colored 7 touch LCD-display.
