I. Usage and Features:
HG30A-3TypeMulti-functional Calibration InstrumentThis is an intelligent AC and DC standard voltage and current calibration instrument (with AC output displaying true RMS values). The instrument features three display windows, capable of simultaneously showing the actual output value, percentage, and the full scale value of the measured gauge. The output of the instrument can be set based on the full scale value of the measured gauge.RangeAnd can be selected according to the scale of the inspected gauge. Output adjustment options are available.Keyboard(Keypad) control or potentiometer control. Features digital display, error direct reading,RangeWide range, fine gradation, high precision, good stability, and easy to use. Suitable for calibrating, inspecting, and repairing four-and-a-half-digit multimeters, various 0.2 and 0.5 class below pointer-type AC and DC voltage and current meters; also serves as a high-stability test power source, used 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 volume, shown in both actual value and percentage.
2. UtilizeKeyboardRegulate the increase and decrease of output quantity.KeyboardControl quantities are 100%/N, 10%/N, 1%/N, 0.1%/N (N represents 4, 5, 6, 10, 15).
3 、External Control RegulatorThe controller allows for off-line adjustment of output quantity increments.KeyboardTwo configurations available, switchable at will.
4. AC and DC voltage output range: 0 to 1050V.
5. AC and DC current output range is 0 to 25A.
6. The communication provides four output frequencies: 50Hz, 60Hz (59.7Hz), 400Hz, 800Hz, 1200Hz, for useCrystal OscillatorEnsure accuracy and stability of frequency.
7. Overload protection with automatic shutdown and manual reset.
8. The 50Hz output can also be synchronized with the local power supply to minimize the impact of beat frequency on the meter being tested.
