If I connect a Bicron P-12 (a low impedance socket) to a GS1100 PRO, without any probe, Setup.jpg if I exceed 1200V PRA reads several counts per second. I made some tests at different voltage, if I increase the voltage the situati...

I volunteer! :-):-):-)

In this case, is it still possible to supply the GS from another source and not...
