HG30 Series Multi-functional Calibration Instrument

I. Purpose and Features:
HG30 ModelMulti-functional Calibration InstrumentIt is an intelligent AC/DC standard voltage, current, and frequency calibrator (where the AC output is displayed as true RMS). The instrument features four display windows, allowing simultaneous display of actual output values, percentages, the meter's full-scale value, and output frequency. The instrument's output can be set based on the meter's full-scale value.RangeAnd the stepping amount can be selected according to the scale of the inspected table. Output adjustment options are available.Keyboard(Keypad) Control or Potentiometer Control. Features digital display, error direct reading,RangeWide range, fine gradation, high precision, excellent stability, and easy operation. Suitable for calibration, inspection, and maintenance of 3.5-digit digital multimeters, various 0.2-class and below pointer-style AC and DC voltage, and current meters; also serves as a high-stability test power source, paired with high-grade standard meters to calibrate 0.1-class current and voltage meters.
II. Main Functions:
1 、5  ¹/₂LED digital display with output quantity shown in both actual value and percentage.
2. UtilizeKeyboardControl the increase and decrease of output quantity.KeyboardControl ratios are 100/N, 10%/N, 1%/N, 0.1%/N (where N is 4, 5, 6, 10, 15).
3 、External Control RegulatorThe controller allows for off-line adjustment of output quantity increments.KeyboardBoth configurations available, easily switchable.
