This manual covers the operation, specifications, and maintenance of the Huaguang HG30-II B multifunction calibrator for testing current and voltage meters.
The Huaguang HG30-II B is a multifunction calibration instrument designed to verify and calibrate ammeters and voltmeters with accuracy classes below 0.2. It functions as a high-stability test power supply, supporting both AC and DC output for current and voltage across various ranges. The device also includes features such as overload automatic protection, manual reset capabilities, standard resistance output, and clamp-on meter measurement functionality. This manual is written in Chinese.
| Accuracy Class (Tested) | Below 0.2 class |
|---|---|
| DC Current Output Range | 0～100uA to 20A |
| AC Current Output Range | 0～100uA to 20A |
| Stability (DC) | < 0.01% of full scale / 2 min |
| Power Consumption | < 180VA |
| Operating Temperature | 5℃～35℃ |
Yes, it provides 20 different standard resistances for calibrating multimeters.
The manual states that during large current output, the duration should not exceed five minutes.
The device must be used in an environment where the temperature ranges from 5 to 35 degrees Celsius.
