DO30-Q+ multifunctional clamp meter calibrator


The DO30-Q+ clamp meter calibrator (hereinafter referred to as the calibrator) is an integrated AC and DC standard voltage and current calibration source with LED digital display meter source (the AC output is a true effective value display). In the three windows, 5 1/2 digits display the actual output value, 4 digits display the percentage of the output range, and 3 digits display the full scale value of the meter under inspection.

  • Product description
  • The DO30-Q+ clamp meter calibrator (hereinafter referred to as the calibrator) is an integrated AC and DC standard voltage and current calibration source with LED digital display meter source (the AC output is a true effective value display). In the three windows, 5 1/2 digits display the actual output value, 4 digits display the percentage of the output range, and 3 digits display the full scale value of the meter under inspection. The full scale value of the meter under inspection can be set, and the corresponding step amount can be selected according to the scale of the meter under inspection. Amplitude adjustment can be controlled by button or potentiometer. It has the characteristics of digital display, wide measuring range, fine binning, high precision, good stability and easy use. It is suitable for calibrating, inspecting and repairing four-and-a-half-digit three-purpose meters, and various pointer AC and DC voltage and ammeters below level 0.2 and level 0.5. It can also be used as a high-stability test power supply to cooperate with high-level standard tables to calibrate 0.1 Level current and voltmeter. It is widely used in quality inspection measurement and instrument maintenance in industrial and mining enterprises, scientific research institutes, railways, electric power, schools and other units.

    AC: ±(0.05% of reading value + 0.03% of full scale)
    * Stability: AC<0.02% of full scale DC<0.01% of full scale
    * Distortion: <0.5%
    * Ripple coefficient: <0.5%

    Scope of application
    * Amplitude adjustment has digital adjustment and analog adjustment functions, which can realize continuous, fixed value and fixed point output.
    * Widely used in quality inspection, measurement, teaching and research and instrument production and maintenance in industrial and mining enterprises, scientific research institutes, railways, electric power, military, schools and other units.
