The calibrator of withstand voltage tester (hereinafter referred to as HYG2670G calibrator or calibrator) is positioned at 0.5% accuracy, and can calibrate the calibration device of withstand voltage tester with the highest accuracy level of 2. It is suitable for withstand voltage tester with maximum output voltage of 15 kV, including digital and pointer AC power frequency, DC withstand voltage tester, withstand voltage part of safety performance comprehensive tester and withstand voltage part of insulation withstand voltage tester. It is an automatic calibrator for first verification, subsequent verification and use verification. It can also be used as a standard high voltage meter for precise measurement of 0.1kV-15kV AC/DC voltage or as an ammeter alone. The calibrator can automatically measure the effective value of AC and DC output voltage, the holding time of output voltage, the distortion of AC output voltage, the ripple coefficient of DC output voltage. It can measure the effective value of AC and DC breakdown alarm current with resistance box (optional accessories) and the voltage drop measurement method under half load to realize capacity test.

The above measurement parameters meet the requirements of JJG795-2004 "Verification Regulations for Voltage Withstand Testers".
