If you are testing at the socket front, switch on the switch then off a few times, also put the plug in and out a few times your reading will drop as it will remove dust and poor contact at the switch.

HP is better. However having worked in Germany a crusty cheese and ham roll with scharf sauce is really good for hangovers...Bacon roll with ketchup ...
Looks like you are using the wrong figures Mate should be R1 PLUS R2 which on this case it would be 0.36 +0.6/4 you have calculated it with r1 +rnSo I’ve finished a rewire recently and I’ve come to testing the ring circuit for the down stairs sockets and I’m not getting what I’m testing in regards to the calculation
LL: 0.36
NN:0.36
EE:0.60(there abouts)
Now when I’m doing the r1+r2 crossing the opposite live and earths but the calculation for obtaining it isn’t what I’m getting when recording the results.
So 0.36+0.36/4= 0.18
But when testing at the sockets I’m getting readings of 0.30 ohms. I’m going to try another calibrated tester this weekend.
Any advice would be appreciated
Thanks
It was earlyThink you've speed read the other posts Pete.
As Vortigern. I recently installed a new RFC and on testing at the sockets just flicking the switch a few times can give quite significant drops in resistance.If you are testing at the socket front, switch on the switch then off a few times, also put the plug in and out a few times your reading will drop as it will remove dust and poor contact at the switch.
I wondered when you would spot it he was doing r1 + rnDirty or unused sockets can give odd readings ...
But you are calculating it wrong ....
0.36 + 0.60 = 0.96 / 4 = 0.24
You sure about that?I wondered when you would spot it he was doing r1 + rn
