Bizarre readings

Wrong end of stick ?

I have never used Ethos gear, just wondering what symbol it uses to show an open circuit on continuity tests, it isn't an O by any chance? Or did the tester actually say 0.00 ohms for the reading?

You're getting a result of half an ohm over a 5m run of cpc (presumeably 2.5T&E) in a ring??!! Come on man, THINK!

Try READING. If I can see 5m of perfectly undamaged sheathed cable I can see that there is no dead short for at least 10m, therfore, even if there was a dead short just out of sight, I would expect a reading of 19.51 x 10 mOhms. Have you ever heard of a 5m ring main??!! Come on man, THINK!

Yep.....as I thought. What's the resistance of 10m's of 1.5mm2 copper conductor? (Try looking it up)

Did you try testing the RFC at a "mid" point??

Come on OP, please answer this.

Not sure you can find it in the Beano though
