Most accurate Insulation Resistance tester out there?

Yeah, ....for about a micro second!! lol!!

Nothing to do with making OTT presumptions, a typical journeyman electrician, (as well as many small electrical contractors) would not carry such test equipment. Primarily because they wouldn't ever have a need for such test kit....

So when exactly have you, or anyone else ever used a 4 terminal micro ohm Ductor tester, to test a circuits wiring?? It's a totally inappropriate tester, and not what the OP was asking about!!

as recent as last week actually. Measuring r1r2 on 100 metre runs of 240mm conductors in parallel, 12 cables in total.
the instrument reading was bang on the pre-calculated values as well. Well worth the 40 quid a week hire charge.

i obviously wasn't as entirely clear on the OPs requirements as you were. Didn't realise he was a typical journeyman spark either....

Really, i thought it was pretty clear what the OP was asking, and it wasn't anything to do with a 4 point Ductor tester!!

So how did you link out those 240mm parallel conductors at one end then??

By twisting then together?

Probably did too!! lol!!

I just can't understand why you would conduct r1 r2 testing on parallel 240mm conductors?? Calculation is more than satisfactory. I certainly wouldn't conduct such tests on what sounds like a main supply, or large sub main....

Oh really ? Lol

calculation or presumption ? Seems more in keeping Lol

Ha ha, ....Come on clever cloggs, tell us how you conducted these pointless r1, r2, r n tests with the DLRO 10??
