Jordan at Artisan & Cory used the metrel and they both said they just couldn't get on with it & TBF this video tend to prove their point

I don't seem to recall them using this Metrel version. Everyone tends to have a favourite when it comes to test equipment. We swap regularly between lots of different testers and manufacturers and we don't struggle. Some people like menus some prefer big buttons.

How do you test lighting circuit with this? I guess remove all bulbs / LED drivers first? If so some installations might be really hard or near impossible ( high ceiling flush 240V fittings)...?

@@Dog-whisperer7494 One should do that with the non hinged part of the cock clip, just is case there is additional resistance in the hinge/spring. also, that resistance could be variable on how open or closed they are. so by connecting the other way round one would eliminate that resistance

Why are the N+PE probes connected? Is it for a cut-down version of a 4-wire Kelvin connection?

@SparkcatcherFox Жыл бұрын

Must be something like that. IR is the only test they insist you do with N and PE shorted. According to the book: "Follow the correct test wiring as indicated in terminal voltage monitor when the particular insulation test is selected. If only two test wires are connected, and L-N, L-PE or N-PE test is selected, then technical specification for INSULATION ALL applies." The accuracy spec listed for INSULATION ALL is worse than the other INSULATION spec.
