Anyone have or used one.

My mft often gives odd readings on eli, wondering how accurate this one is...

which mft?

have you checked for loose connections?

are you getting stable r1,r2 and rn values?

if you are then it might be the suppliers side is loose and thats affecting it

Its a dilog 9083p - not all that.

Not had it long but it seems to give odd results, it runs a 'no trip' test, looking at other threads others have commented on it too.

Has anyone used the Martindate i mentioned?

no trip tests are not as reliable as high current zs/ze test

We had a situation the other day where the RCD was making the Zs readings high. Linked out and all was fine.

You could use the alternative Zs method on high loop and compare to a no trip and see what the results show.


When was your tester last calibrated?

Its not long been calibrated.

I think its problem with this tester.

Looked at a Martindale in the wholesalers the other day, seemed neat, and was cheap - wondered if it suffered like my Dilog does.

paul dont forget that some mcb's,rcd's,relays and overloads can all affect the zs value

Paul - you should take a reading in your own house and test the MFT regularly noting the reading each time - then you will have a reading you can trust.

Different RCD's will and do give different readings!

If you've not had it long and it is not operating correctly then return it for repair or replacement.
