Specifications
The Three Phase Reference Standard Meter (GF312D) is portable meter test equipment from GFUVE Electronics. The main objective of this device is to calibrate the errors for three phase & single
phase energy meters i.e. the meter under test (MUT). The GF312D supports both static and electro-mechanical types of energy meters. It can also be used to measure the voltage, current, power, energy,
power factor, harmonic etc of the meter under test. It has an 6 inch color LCD display, 24pcs keys that makes it easy for the user to operate the GF312D reference meter. It can be interfaced with the
PC for data management analysis. It has the capability of storing test results. YOU CAN ALSO LOOK IT

The reference standard meter supports various current modes for checking energy meter error. The high accuracy (0.05) mode operates for direct current up to 20A. The clamp on CTs mode
accuracy is better than 0.2 class. It can also be used to determine the current transformer ratio when tested simultaneously on the primary and secondary sides. It also supports flexible current
probe for very high currents like 2000A or 3000A.
