Hello,
I've purchased a VC60B+ a few days ago, which is an insulation tester branded under different names (Victor, Vici, and others).
It came with a Chinese manual which I can't read. On the net you find these manuals:
https://core-electronics.com.au/attachments/VC60B+%20User%20Manual%20(English).pdfhttp://www.analogti.com/document/VC60B.pdfhttp://micromir-nn.ru/insulation/VC60B.pdfThe sentence which confuses me is this:
"6、When measuring cable, connect G Terminal to the protection loop."
Normally, you have to connect L and E, the two outmost terminals, in order to measure the isolation resistance. For which purpose should I have to use G? And, should G be connected to the earth conductor of the cable? And, what could be the possibly adverse effect if I don't comply to this rule?
The biggest problem with such a low-cost device is probably that you don't receive a proper and responsibly written manual in a good language, at least neither in German nor in English. These translations from Chinese to whatever are between totally useless or at least dangerously confusing... So, to get an advice from an experienced electrician would be great! I'm just a beginner and mere amateur...
Thanks a lot beforehand,
have a good time,
Hartmut
