Multifunctional Testers - Which one have you got and how long has it lasted?

[pc1966]

I can't see any normal testing causing that sort of a fault as MFT are designed to trip-test stuff that could potentially have the odd fridge compressor motor still on it, etc.

It sounds more like some whisker of metal internally is shorting something out so probably a one-off.

Cheers that is an interesting angle on a possible -failure mode !

I know sounds silly, and its clutching at straws but everything was in the place was on a spd extension leads.
I didn't pay too much attention at the time but he did mentioned that the mcb for the rfc tripped once when he was reset the RCD while carrying out the auto test.
We unplugged everything carried out the test again and it was fine.
My thought was maybe one of these spds dumped to earth when my mate was resetting the RCD and my poor dilog took the brunt.

Well if you have a new MFT and no intention of paying for the old one to be repaired there is nothing stopping you opening the old one and blowing/brusing it out in case it is a tiny bit of metallic contamination. Obviously without out it connected and batteries removed!

Personally after just two years if treated well I'd get straight on to DiLog.

Also worth checking the date of purchase as I believe they're warranted for 2 years.

My trusty Megger 1552 died last Saturday, keeps on blowing the fuses and tripping RCDs on the no trip setting. I was due a new tester after nearly ten years of arduous service, opted for Metrel in the end:

as there is no button for RIP Megger, will just have to say long live Metrel

If you want. Do you just want the unit or all the gubbins with it as well such as leads etc?

You can also have the calibration cert that's less than two months old... ??
