Yep if it's damp/corroded inside or is an RCD socket.

No never have

As above, if it's an RCD socket then it will give a low reading. A 500v test may cause damage to such a socket. Otherwise if its a standard socket you can always IR the terminals of the disconnected socket to verify.

What is it reducing the reading to?

 

[Pete999]

What, are the IR readings with, or, without the socket being connected? Does the IR alter if you just slacken the front plate from the back box?

Has it got a little neon indicator on it?

Well therein, lies' your problem I think. Were your IR test L to N? or LN to E

 

[telectrix]

neon should only affect the IR if the socket switch is in the ON position.

Hi its between line and neutral the line conductors and cpc are fine I am not on site but I can not recall it having a neon but could be a poss

Agree Tel but we have nil info on test results or how the tests were carried out.

As per Tel' response, test with the socket switched off, or removed from yje back box bye still connected, AND GIVE US THE RESULTS OF YOUR TESTS PLEASE.

 

[plancaster]

the reading was between line and neutral read low and the line and earth was fine as for the neon mmm I can not recall if it has one

What is LOW?

If it is one of these then it is the neon most likely:

Out of curiosity has anyone used one of them? For £10 it seems very cheap but maybe it is OK.
