Hi,

This is my 1st post so please be kind to me........ ?

Whilst carrying out Ring Main Continuity either r1-rn and/or r1-r2 I have been getting differing results at various sockets by way of the plug top tester. The ring tests out fine when using probes on the back of the sockets. For example the healthy r1-rn was 0.4. At some sockets using the plug top test a double socket would give me 0.6 onside and 1.10 on the other - but all OK testing from the terminals at the rear.

I understand that this is probably down to lack of use - is there any limit to the losses through the socket.

They all tested out OK doing Zs. 

Am I being over cautious?

Many thanks
