  • Product description
  • The DO30-E three-purpose meter calibrator (hereinafter referred to as the calibrator) is an integrated AC and DC voltage and current calibration source with an LED five-and-a-half-digit display and meter source. Equipped with eleven kinds of standard resistance, it is convenient to calibrate the resistance range of the multimeter. It is equipped with millivolt gear output to meet the detection of special instruments for railway locomotives and instruments with millivolt gear. The calibrator adopts advanced technologies such as digital technology, large closed-loop amplitude stabilization, true effective value conversion, powerful power amplifier, automatic protection, etc. to ensure its good stability, strong load capacity, safety and reliability. It is suitable for calibrating and calibrating various current and voltmeters below level 0.2. It can also be used as a high-stability test power supply, used in conjunction with high-grade standard tables, to calibrate current and voltmeters above level 0.2.
    It is widely used in quality inspection, measurement and instrument maintenance in industrial and mining enterprises, scientific research institutes, railways, electric power, troops, schools, etc.
