voltagecurrentfrequency

GF3021 Portable Multifunction Instrument Calibrator is suitable for power plant and power grid companies for the following function: measuring and testing department and instrumentation classes, national levels measuring and testing institutions, railway, petroleum, chemical industry and other large industrial and mining enterprises, scientific research units, etc. The core technology function with digital signal processor (DSP) and 16 high-speed digital converters composed of high precision work frequency communication terminal. The signal source is DSP and 16 high-speed digital-to-analog converters, it can control the sine wave and distortion wave signal source. FUNCTIONS AND FEATURES All kinds of electric measurement transducer can be checked, including AC/DC voltage transducer, AC/DC current transducer, frequency transducer, phase transducer, single/ three-phase AC active power transducer, and 3-phase reactive power transducers. Check all kinds of electric measurement indicating meter, including AC/DC voltmeter, AC/DC ammeter, frequency meter, phase meter, single three-phase acjige active power meter, three-phase ac reactive power meter, synchronous meter, etc. Test single-phase, three-phase electronic, mechanical watt-hour meter or energy meter/ kWh meter error. Calibrate AC sample device, RTU, measurement device error. 5The built-in electric measurement transducer, electric measurement instrument and meter instructions of verification procedures, can fully automatic or semi-automatic for verification, and save 1000 group check data. It can be used as voltage source, current source and power source with high precision, and it is a high stability standard resource.
