1v showing after isolation

[m4tty]

Hi,

Checking at FCU put in for shaver socket after isolation to prove dead and MFT1552 showing 1v L/E. Is this a problem??

Thanks

megger says 1v when not connected to anything.... though not sure what the L/E this is that you mention

You ought to get yourself a decent test lamp M4tty! If Paul is right (above), & I have no reason to doubt him your tester shows 1v when you switch it on (I think he meant Line to Earth Paul).

Get yourself a decent self proving voltage tester, the Kewtech Kew 1700 is pretty good & it also does phase rotation. It is about

i use a fluke T100, would lot be without it. easyer to carry around that a megger, and less chance of bashing the megger too

Thanks for replies i have got a Fluke T100 too but bought the MFT last week so have been trying to get used to it and i know its wrong but i like to see a voltage reading ie 246 or 237v as if you dont make good contact with the T100 the led's dont light. Probably me being silly tho. Thanks again

i have a 1552 and when on volts it has 1v on display

probably nothing to worry about. a MFT isnt really the tool of choice for checking dead

heres a question for you though, why does the fluke still beep, as if continuity when a circuit is dead?

 

[m4tty]

i thought the same when using it on a lighting circuit but just put it down to it reading continuity through a bulb or summin ??

well, your gonna get a beep from neutral to earth, and maybe reading through a lamp when doing L-E and L-N.

well done sellers, just testing that you know your stuff
