Product description

1. Product introduction
HG7502 is another seven-and-a-half-digit multi-functional calibrator launched by our company in recent years. It has the characteristics of multi-range, wide range, high precision and good stability. The instrument can output high-accuracy DC voltage/current, AC voltage/current, DC power, and AC power with power factor control. It also has functions such as resistance simulation, capacitance simulation, function wave output, pulse output, and DC voltage and current measurement. , suitable for calibrating or verifying various voltmeters, ammeters, power meters, power factor meters, phase meters, frequency meters, multimeters, multimeters, various power measurement transmitters and other calibration devices below level 0.01. It can also be used as a calibration device Standard sources used. This instrument fully complies with the relevant requirements of JJF1284-2011 "Calibration Specifications for AC and DC Ammeter Calibrators" and can be widely used in quality inspection and testing of industrial and mining enterprises, aerospace, military industry, scientific research institutes, railways, electric power, military, schools and other units. Measurement, teaching and research and instrument maintenance work, etc.
