I'll just throw this out there.

When doing R1+R2 at the sockets what
Items do you use regarding leads or so.

I link out at the board with kewtech jump leads as in post#4, and test at each point using a kewtech socket adaptor, similar to post #2.

Perhaps I'm missing a trick here, but I can see problems with using a linked out plug for this? Surely each time you move the plug to another point on the circuit, you have to walk back to the board to confirm the reading on the MFT? Also, without disconnecting the CPC from the board, would parallel paths not be more likely to skew the results?

There may also be a pedantic Peter that says the tests won’t be valid as the linked out plugtop isn’t a proper piece of test equipment…. Not authorised adaptor etc

Maybe they would accept a 4mm plug-top adapter and a standard test lead between L and E

Surely each time you move the plug to another point on the circuit, you have to walk back to the board to confirm the reading on the MFT?

If working alone, yes.
I sometimes take the tester when plug is fitted, and test each point to the far end of the circuit on the way back, checking for a sane increase each time. All depends on size of installation.
If it's a complicated circuit with branches I'd revert to normal methods though!

Old 13amp plugtop with a link between L-E , plug this into a socket and test at the board

The linked plug seems a good idea

That's what I made one yesterday by soilering the link to earth and live with out the fuse..
