OK - apart from all ye well experienced sparks out there - I thought this might be useful to the rest of us mere mortals ......
I did a Zs on a RF socket cicuit recently .... one particular socket had a reading of 123ohms, the rest were well within the 1.15ohm max for the particular protective device.
I opened the socket and the backbox was rusted but dry, and the terminals on the socket were so oxidised that they were deep green-blue. The exposed conductors were also well oxidised.
I filed the conductors down to shiney copper again, and put a new socket on and voila .... Zs there down to 0.9.
So don't immediately panic that there's something badly wrong!
