The GF312D1 three phase portable energy meter test equipment 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 GF312D1 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. The Three Phase Portable Standard Meter GF312D1 is a portable standard to verify active and reactive three phase meters (3 or 4 wires) and single phase meters. It is designed to work in the field or lab.
