  • Product description
  • The O30-E+ multifunctional calibrator (hereinafter referred to as the calibrator) is a calibration source for LED five and a half digit display of AC and DC voltage and current. It has high output power and strong load capacity; it is equipped with RS232 interface, which can be connected to the computer. The system software is reasonably designed and complies with the new national metrology regulations; it realizes the automatic processing function of test data; the unique protection circuit makes the operation of the calibrator safer and more reliable.
    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.

    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 to choose from: 25Hz~3kHz (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 0~750A (some meters can measure more than 1000A); the conversion error is ±0.8%.
