Easy Tutorial: Insulation Resistance Test with Essential Tips

In this video, we are using the Metrel MI 3152 BT multifunction electricians tester to carry out an insulation resistance test on a radial socket circuit. We also explore common insulation testing mistakes that apprentices make during an AM2S assessment.

These tests are always carried out on perfect circuits you should to a typical system with problems and go through things resolving them as you go

Thank you for this video; very informative.

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

[@efixx]

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.

@@efixxwhy would u test @ 500 ? Is that not just for installation certs

[@jeremylister89]

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)...?

[@dansheppard2965]

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

[@SparkcatcherFox]

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.

Hi I need some help if you can I need someone that fix Metrel meters because I phoned Metrel and didn’t help because they told me that they only sell to authorized dealer or representative only the Maltese representative told that he can’t help so if there are someone here that point me to someone that can sale me parts maybe I can fix my Metrel meter please thank you for any help kind regards

Naughty Garry connect your croc clips properly @ 4:00

[@MarkUKInsects]

I spotted that too, but you beet me to it on the comments!

[@Dog-whisperer7494]

Why hasn’t he contacted the crocodile clips properly? They looked ok to me

[@MarkUKInsects]

@@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

The only thing missing is WHY the cpc needs to be connected....

[@skiv36]

There's me thinking the paid promotion was going to be for Metrel. Turns out it was for Tesco!

[@efixx]

😂 every little helps

[@sunshine3187]

I've always disconnected the earth when ir testing, I don't see the issue with either way.

[@jameshansing5396]

Google or look in guidance notes ..

[@danhumphreys5050]

Why does the Earth have to remain in the earth bar ?. I’ve just done insulation resistance on my AM2s exam and I removed the earth from the earth bar.

[@jameshansing5396]

They should have flagged that as being wrong….
