  • Product description
  • The DO30-I three-purpose meter calibrator (hereinafter referred to as the calibrator) is an integrated AC and DC voltage and current calibration source with LED five and a half digit display meter source. It is equipped with millivolt gear, which meets the requirements of the detection of special instruments for railway locomotives and instruments with millivolt gear. It is equipped with RS232 interface, which is convenient for networking with computers for automatic data processing. It adopts European-style chassis, which is small, light and easy to carry.
    This calibrator is mainly suitable for calibrating and calibrating various current and voltage meters below level 0.2 and multimeters with corresponding accuracy. It can also be used as a high-stability test power supply, and can be used with high-grade standard tables to calibrate current and voltmeters above level 0.2. It is widely used in quality inspection, measurement, teaching and research and instrument maintenance in industrial and mining enterprises, scientific research institutes, railways, electric power, troops, schools and other units.
