Hello
Like some here, if bought this cheap Chinese Insulation Tester "Vici VC60B+" from AliExpress.
There a controverse manuals available concerning the E and L terminal usage, you can read either:
E: Input terminal for the measuring object.
L: Terminal for connecting to the GND of the measuring object.
or vica-versa:
L: Input terminal for the measuring object.
E: Terminal for connecting to the GND of the measuring object.
When I measure the output ot this two terminals, I can see that L is the positive (+) terminal and E is the negative (-) terminal.
I assume E stands for Earth and L stands for Line(?)
If I use this terminals this way or vica-versa, I wonder if that does not matter at all? Or is important in some cases? Or is important in any case?
Thanks
