I havent come across this before, wondered if its common and what it signifies in the ring.
Remeasured 3 times and got within 20mohms or so each time so pretty sure its not a zeroing the meter thing.
2.5:1.5 TW/E ring. I went around all of downstairs rooms, did min of few sockets in each room nice even results all the way around. Just not 1/4 of r1, r2 etc
r1=1.15
r2=1.82
rn=1.13
R1+Rn =0.57 (approx half)
R1+R2=0.78 (only a little bit less than half)
Any ideas?
PS Job was to move a socket and add a couple more.
Install is in <10 year old house, doesnt look to have been messed about much apart from has had an extension added in the last few years.
