Dave ... get them , burn them , stress them , let the probes melt down ..
10A at 1000V = 10 KW ... lets see who is the " Man "
Fluke ,Hirschmann, Gunson , Textronic , Chinas unbranded or branded .. like those Chi-Shing .. and add others too ...
Test , probes , crocks , cables .
Built one load with resistors , throw it in a bracket with watter , and at 35V throw 30A current to them ..
Just an idea ...
