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

[pc1966]

My DL9118 will do type A RCD but not type B, though so far I have not encountered one in actual use which makes it academic to date. So that would be a 2nd reason for getting the Megger.

As you say, being able to test EV point is likely to be a growing market as part of other EICR/PAT work.

Lasted around 2years

a) Do reckon you treated it carefully ,or had it seen a fair bit of rough n tumble.
{ B) Too tired to be working + Dropped it !
.. have we all been there - just got to finish before home ? }

Got a Kewtech KT63, now about 7 years old, just had to replace the leads

I looked after it, test leads always coiled up nice after each use too..
The only thing I can thing of is prior to this I got my trainee to carry out a RCD test at a property that had loads of surge protected extensions leads. He left them plugged in along with other stuff when doing the auto RCD test.. Only thing I can think of.

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

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.

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!

I will I'll post some pictures too ?

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

any chance i can have your old 1552 for an experiment i'm working on? even for spares?

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... ??
