Three Phase Electrical Test Equipment Energy Reference Standard Meter

Portable Three Phase Multifunction Power and Energy Reference

Standard Meter

The GF333B is a three phase reference standard meter which has been especially developed for universal laboratory and test area use. It is intended for checking and calibration of reference standard power and energy meters, for calibration of precision current and voltage sources and for verification of electrical standard measurements and electricity meter test systems.
The three phase reference standard meter uses analogue - digital converters (ADCs) for its data acquisition, these being controlled and read by a digital signal processor (DSP).
The three phase reference standard meter may be directly connected to an external computer system over its RS 232 C serial interface.
The three phase reference standard meter is distinguished by having very wide measuring ranges for all AC values while still being of accuracy class 0.02%:
Voltage: 0 V ... 600 V
Current: 0A ... 120 A.
In addition, low currents from 1 mA are measured. Range selection may be made either manually or automatically.

GF333B is a portable reference standard meter used to test three phase meters and single phase meters, it designed to work both in the field and in the laboratory.
