PY 822 Current and voltage calibrator is a kind of high precision, high resolution and high reliability handheld calibration instrument which integrates output and measurement of V, mV, mA and HZ signals. The meter adopts a large LCD display with clear readings, while the meter also has an adjustable backlight and an automatic shutdown function. The meter can be powered by DC or AC power supply, which is more convenient to use.
It can replace the current signal source, voltage signal source, resistance box, electronic potential difference meter, frequency meter and other measurement and calibration instruments. Mainly used in industrial field signal calibration, fault diagnosis; also suitable for chemical industry, military industry and all kinds of research institutes, laboratory signal measurement and calibration.
