Front Terminals
1 – RTN/Low: This terminal connects to the RTN/LOW terminal on the high voltage module of the 19501 partial discharge tester, which is a low potential terminal. This terminal is almost equal to the ground terminal on the chassis.
2 – Low Contact: This terminal connects to the HVCC-RTN terminal on the high voltage module of the 19501 partial discharge tester.
3 – HV Contact: This terminal connects to the HVCC-HV terminal on the high voltage module of the 19501 partial discharge tester.
4 – HV: This terminal connects to the HV terminal on the high voltage module of the 19501 partial discharge tester. Do not touch during testing and when the DANGER light is on.
