HG30-IIB digital multimeter calibrator, digital multifunctional calibrator, multimeter calibration device, multimeter calibrator The HG30-IIB digital multifunctional calibrator/multifunctional three meter calibrator is suitable for verifying and inspecting various AC current and voltage meters at level 0.2, including AC and DC voltages ranging from 0 to 1000V and AC/DC currents ranging from 0 to 20A, with eleven levels and two valuesresistance. This instrument adopts digital oscillation technology, which provides more accurate, stable and reliable output current and voltage; Take overload protection safety measures, which can automatically stop the output protection equipment from being damaged in case of operator errors; The output adjustment adopts two methods: panel and numeric keyboard, which can be output in fixed value step by step, making it easier for the staff to operate. So in addition to its high accuracy, stability, reliability, and ease of use, the operation is safer and more convenient. Mainly used for verifying various corresponding precision multimeters, ammeters, and voltmeters, suitable for use in measurement and testing, instrument production and maintenance, and quality inspection departments. Choosing a clamp gauge standard coil can verify the AC/DC clamp gauge; Choosing computer software can enable online operation with the computer. Main technical performance parameters: This instrument is suitable for ambient temperatures ranging from 0 ℃ to 40 ℃; Working in an environment with a relative humidity below 80%, using AC 220V ± 10% power supply, power frequency 50Hz ± 5Hz, and maximum power consumption not exceeding 150W The output range and accuracy are shown in the table Wave distortion not exceeding 0.5% Ripple coefficient not exceeding 0.1% Working hours: continuous Stability:<0.02% of full scale for 5 minutes Dimensions: 159 × 400 × 420 (mm) Weight: 16kg
