Patent number: 10944259Abstract: A system and method of protecting measurement circuits from a potentially energized device under test (DUT). In one embodiment, the DUT is a capacitor that has acquired a charge though some means prior to needing to test it. In this embodiment, a circuit is provided that protects the measurement circuit by both limiting the current to the measurement circuit while simultaneously dissipating the energy stored in the DUT. In a further embodiment, a detection circuit is provided to measure the voltage at the terminal of the DUT. Only when the magnitude of the voltage is lower than a specific threshold will the measurement circuit be switched to and connected with the DUT.Type: GrantFiled: October 8, 2018Date of Patent: March 9, 2021Inventor: Cheng Bao
