Hi all,
Seeking used, (battery powered, not hand crank) insulation testers...
Specifically, units capable of placing 1kV, 2kV and 5kV DC on an isolated circuit [e.g., PV module strings] to check for leakage to equipment ground.
I already have a tif IT990, and a Fluke 1507, but links/resources/recommendations for other products would be appreciated.
Thank, D.
