I agree BUT Zs is a Live test which in the sequence of testing is a long way down the list as regs state
612.2.1
612.2.2

Continuity must be proved inc the CPC so your earth path should be proved before doing a Live test

How do you put a temporary bypass on a Rcd main switch,to stop it tripping when you are testing with equipment that doesn't have the non trip function.
 
????? it's not april 1st yet, is it? if there's no isolator before the CU, paul, don't even attempt it. graveyard's overcrowded as it is.

simple answer is to get a tester with no-trip or calculate the Zs from Ze+R1+R2.

There is a very simple way to do what you describe without by passing anything. The clue is in the word Loop and if you know your electrical theory then you should be able to work it out. As I don't know your level of competence I'm not going to explain any more.
