1. Summary
TD1230 is designed based on TUNKIA's latest Integrated Precision Measurement Architecture (IPMA) (1). It is suitable for the calibration of Class 1, Class 2, and lower accuracy AC/DC withstand voltage testers. It can also be used to calibrate the withstand voltage test section of electrical safety multifunction testers and insulation withstand voltage testers.
