I. Application & Features:
HG30A-3TypeMulti-functional Calibration InstrumentThis is an intelligent AC and DC standard voltage and current calibrator (where the AC output is displayed as true RMS). The instrument features three display windows, capable of simultaneously displaying the actual output value, percentage, and the full-scale value of the meter under test. The output of the instrument can be set based on the full-scale value of the meter under test.RangeAnd the step size can be selected according to the scale of the inspected gauge. Output adjustment is optional.KeyboardPush-button or potentiometer control. Features digital display, error direct reading,RangeWide range, fine gradation, high precision, good stability, and easy to use. Suitable for calibration, inspection, and maintenance of 4.5-digit multi-purpose meters, various 0.2-class and 0.5-class or lower pointer-type AC and DC voltage and current meters; also can be used as a high-stability test power supply, paired with high-grade standard meters to calibrate 0.1-class current and voltage meters.
II. Main Functions:
1 、5  ¹/₂LED digital display output quantity, showing both actual values and percentages simultaneously.
2. UtilizingKeyboardControl the increase and decrease of output quantity.KeyboardControl quantities are 100%/N, 10%/N, 1%/N, 0.1%/N (with N being 4, 5, 6, 10, 15).
3 、External Control RegulatorThe controller allows for off-line adjustment of output quantity increments.KeyboardAvailable in two configurations, with seamless switching between them.
4. Output voltage range for AC and DC is 0 to 1050V.
5. AC and DC current output range: 0-25A.
6. Offers four output frequencies for communication: 50Hz, 60Hz (59.7Hz), 400Hz, 800Hz, and 1200Hz.Crystal OscillatorGuarantee the 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 beat frequency effect on the meter being tested.
