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

Recently got a DiLOG DL9118 MFT as it seemed to be a decent enough unit for the price, but don't have any experience to compare that with, say, the Megger MFTs.

However I still prefer my Megger MIT230 for general bond impedance testing (seems a little quicker / more responsive) but mostly because on insulation it goes up to 1G ohm which I have found useful (not domestic testing).

Does anyone else test their MFT against a Cal-Card and a known RCD? Mine gets a run through and spreadsheet log roughly every month. Give me a heads up as to potential issues.

What a great idea!

I have never seen the CalCard before, but I have some other resistor calibration boxes that are not as convenient to carry/keep with the instrument/etc.

Are we the only country to use MF testers ?

I have spoken to sparks from America , Canada , New Zealand , Australia , Greece and Spain non of which use a MF back home

Yes, they don't get used much here in Australia, most sparkys use a multimeter, and have an IR tester and an RCD tester.
I actually purchased a used Di-Log 9083P which is built in the same carcass as a Seaward PAT tester. But I had to purchase that in UK and have it transported to the colonies.
I quite enjoy using it, having so much to choose from on one unit.
We don't have the same procedures as you have in 17th, or I think it's the 18th now!
 
That is interesting to hear. Certainly by time you have bought an insulation tester and a RCD tester you might as well buy a MFT!

However, most multimeters cover a wider range of measurements than the equivalent MFT capabilities, but generally not as capable at the very low (bonding) or very high (insulation testing) resistance ranges.
 
bought my 1553 2nd hand in 2013 from MDJ.. it's now 12 years old and passed every calibration.
 
I have a Megger made in the 1960s. I have had use of it since 1993. I still use it when I don't need a calibrated result. It has a DC generator 500 & 1000VDC. The meter has a current winding and a voltage winding. The result of the two magnetic fields moves the meter hand; effectively an electromagnetic ohms calculator. Just beautiful.
 
I've just done the same, had my trusty Mft1552 since late 2006 and is still passing calibration and never missed a beat.
Just bought the 1741+ and it's every bit as reliable and am very pleased with it. A worthy investment, hopefully it will last as well as the 1552!

After using a wind-up megger for many a year and borrowing from others. Thought I would embrace modern technology and purchased the DiLog DL9110 just over a year ago.

Does everything I need for the occasional domestic work that I do, it's not the quickest when carrying out no-trip tests, but happy with it and its 'relatively' cheap. No issues with it so far, just wish I had paid a little bit more for the next model up that comes with remote test probe.

DiLog state that their remote test probe (TLRP911x) can be used with the DL9110. About £40 to buy separately.
 
Kewtech KT64 V1 6yrs and counting use it for spare internal solder to lead sockets re-soldered.
Kewtech KT64 V2 7yrs + still going strong (above issue not apparent due to redesign) They are solid & reliable

Just wondering which multifunctional testers you guys have, and how long have they lasted?

Hoping this becomes a handy thread for you all. There seems to be a massive price difference between them all. But then I guess some do things others don't? Not sure. :)

Let us know which multifunctional testers you have, which ones you wish you had, and how long the one you have has lasted so far. :D

1994 Meggers, Robin DVMs and clip-on same age, Fluke multi ditto, Hewlett Packard AC/DC clip-on that drew graphs even back then, Clare tester and a lot more even older. All employer provided but donated to me on retirement. Not used seriously now of course!
 
Robin 3 piece tester set , got it when I finisged my apprenticeship

still going strong ? after 20 years
 
I bought a second hand metrel Eurotester several years ago and it has worked without a problem all these years, but it is now looking abit scruffy.
 
My 1552 has died after ten years, long live the Megger... ?
 
I just purchased the Kewtech KT63 which arrived yesterday. Did a quick RCD test and one side of the cu is fine, the other side failed so needs a new RCD.
This is fastly becoming an expensive hobby!

I have my late brother's ROBIN kts 1620 MFT he had from new used it while working for London transport so it has sentimentle value to me and I would love to put it to good use
 
My Dilog DL9118 died in the middle of an EICR on Friday.
Shows a continuity reading of 0.24 on low ohms even with test leads disconected.
Lasted around 2years :(

Had to pop to CEF ended up getting the Megger 1941+ with the new EV adapter. Didn't really want to pay that much. Fingers crossed it lasts.

Bummer.

I hope mine lasts longer, though to be fair it hardly gets much use compared to a professional electrician. If/when it goes I was thinking of the Megger, not really for EV adaptor or anything like that but to have the earth rod testing via two spikes.
 
I have my old faithful Megger 1553, but it doesn't do Type A or B RCD tests.
I'm picking up my Megger 1741+ tomorrow.
I thought about getting the EV adaptor as it would be £120 cheaper to buy it at the same time, but decided to wait until I actually need it.
The reason I think I will need the EV adaptor eventually is that I do a lot of EICRs, and it's just a matter of time before I come across an EV charge point that will need testing as part of the EICR.
It could be argued I suppose that for an EICR you only test up to the point of connection to the fixed wiring, but in view of the potential danger of a malfunctioning or incorrectly installed EV charger, I personally would prefer to be able to give it a thorough test.
Also, an EV charger would not be picked up by a normal 'PAT test', and I doubt any 'PAT' person would have the equipment or knowledge to test one.
Damn I knew should have bought the damn thing! ?
 
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.

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 ? }

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.
 
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!
 
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... ??
