200mA Verification Electric Meter Calibration Shunt Running

Three Phase Verifcation Device ,High Cost Performance,Suitable For Various Occasions,High Accuracy Class,Wide Range

GF302D is a powerful and portable threephase current and voltage source. All test values are generated absolutely synthetically with a high degree of accuracy and stability.

FEATURES

• Able to test basic error, shunt running, start, standard error automatically and manually in single-step of single/three phase, according to relative regulation of kWh meter.
• Able to do change test caused by voltage influence, frequency influence and harmonic influence.
• Output of power source is speedy and stable, AC maximum output of each phase can reach 120A in maximum.
• Voltage, current and phase position of each phase can be adjusted in split-phase, improving the flexibility of power source.
• Frequency of each impulse input port can reach 40Hz.
• 7-inch TFT color display touch screen, English menu, simple and convenient operation, commonly used functions and current basic load point can be controlled in one button.
• Each meter position can provide one standard, dependent RS485 port, and able to perform multi-function test, such as communication test.
• Impulse port of each meter position, external polarity can be set randomly, able to adapt kWh meter of impulse cascade and common-anode.
