zs testing

Now why couldn't I have thought of that much easier explanation instead of drawing this diagram!

Thank you , very clear to understand from the diagrams. Appreciate the help.

you're slightly confused here. when cross connecting the RFC legs, you should get R1+R2 at each outlet will be the same. your Zs readings are taken with the RFC legs connected into the supply, so will be dependent on the resistances when in this configuration. i.e, highest reading will be at thew mid point.

And don't forget that worn or rarely used sockets can give misleading readings, and spurs will too!
