I. Application & Features:
HG30A-2TypeMulti-functional Calibration InstrumentIt is an intelligent AC and DC standard voltage and current calibration instrument (where the AC output is displayed as true RMS). The instrument features three display windows, allowing simultaneous display of the actual output value, percentage, and the full-scale value of the meter being tested. The output of the instrument can be set based on the full-scale value of the meter being tested.RangeAnd the stepping quantity can be selected according to the scale of the inspected table. Output adjustment is selectable.Keyboard(Keypad) control or potentiometer control. Features digital display, error direct read,RangeWide range, fine gradation, high precision, good stability, and easy to use. Suitable for calibration, inspection, and maintenance of 4.5-digit multi-meters, various 0.2 and 0.5 class below analog AC/DC voltmeters and ammeters; 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 value and percentage simultaneously.
2. UtilizingKeyboardControl the increase and decrease of output volume.KeyboardControl quantity is divided into 100%/N, 10%/N, 1%/N, 0.1%/N (N refers to 4, 5, 6, 10, 15).
3 、External Control RegulatorThe controller allows for off-line adjustment of output quantity increments.KeyboardTwo configurations available, switchable at any time.
4. AC/DC voltage output range is 0~1050V.
5. AC and DC current output range: 0 to 22A.
6. The communication offers four output frequencies: 50Hz, 60Hz (59.7Hz), 400Hz, 800Hz, 1200Hz, for useCrystal OscillatorEnsure accuracy and stability of the frequency.
7. Overload protection with automatic shutdown and manual reset.
8. The 50Hz output can also be synchronized with the local power supply to reduce the influence of beat frequency on the meter being tested.
9. Clamp Meter Measurement Function: Equipped with our factory-standard coil, capable of measuring 0-1000A current with an accuracy of ±0.3%.
III. Technical Performance:
1. Stability: AC < fullRange0.02%/5 minutes
DC < FullRange0.01%/5 minutes
The instrument requires a two-hour warm-up for precise measurements.
2. Communication distortion: <0.5%
3. Direct Current Ripple Factor: <0.05% (at rated output)
4. Output Frequency Accuracy: 50Hz, 60Hz (59.7Hz), 400Hz, <0.1% (or sync with AC power)
5. Output voltage and currentMedian ResistanceScope and accuracy are as shown in (Appendix 1) (23°C ± 2°C, output value greater than 10%)Range）
