The DO30-Q clamp meter calibrator (hereinafter referred to as the calibrator) is an AC and DC clamp meter calibration device composed of an LED five-and-a-half-digit display AC and DC voltage and current calibration source and a clamp meter calibration coil. Amplitude adjustment can be controlled by keyboard (button) or potentiometer. It has the characteristics of digital display, wide measuring range, fine binning, high precision, good stability and easy use.

  • Product description
  • The DO30-Q clamp meter calibrator (hereinafter referred to as the calibrator) is an AC and DC clamp meter calibration device composed of an LED five-and-a-half-digit display AC and DC voltage and current calibration source and a clamp meter calibration coil. Amplitude adjustment can be controlled by keyboard (button) or potentiometer. It has the characteristics of digital display, wide measuring range, fine binning, high precision, good stability and easy use.
    Mainly used for calibration and testing of clamp ammeters, and suitable for calibrating and calibrating various current and voltmeters of level 0.2 and below. It can also be used as a high-stability test power supply, used in conjunction with high-level standard meters to calibrate ammeters and voltmeters above level 0.2. It is widely used in production, quality inspection, scientific research and instrument repair in industrial and mining enterprises, scientific research institutes, railways, electric power, troops, schools and other units.

    The main function
    1.1, 5 1/2 digit LED digital display output, which can be displayed in two ways: actual value or percentage.
    1.2. The AC and DC current output range is: 0~100uA~500uA~2mA~5mA~20mA~50mA~200mA~500mA~2A~5A~20A.
    1.3. The AC and DC voltage output range is: 0~200mV~1V~2V~5V~10V~20V~50V~100V~200V~500V~1000V.
    1.4. There are three AC frequencies available for selection: 50Hz, 60Hz, and 400Hz (use a crystal oscillator to ensure frequency stability).
    1.5. Output overload can be automatically protected and manually reset.
    1.6. There is a 10% margin for each voltage and current output range.
    1.7. Clamp meter measurement: Use our factory's calibration coil, which can measure 0~1000A; the conversion error is ±0.8%.
