Ring main end to end and R1+R2 testing query

[Mazza78]

Hi
I'm newly qualified and doing some testing and got stumped upon doing my r1+r2 on a ring main and also end to end tests and the circuit doesn't have an earth cable tot just uses the trunking for its cpc. So my question is how do u fill in test sheet for these or how do you test please?
Thanks

What would you do if it was SWA using the armour as the cpc ,?
