Hoping someone might be able to help. I’ve seen an ‘adaptor’ that allows 2 test leads to run from one port of an MFT (doing IR test). But, can’t find anywhere to buy it. Anyone know where I could get one from?
 
Erm, why would you wat to do that is the obvious question.

The idea of ir testing is to show the resistance between 2 items, if you add a 3rd in to the equation then you have the possibility of joining 2 things that are at different potential and destroying a set of leads amongst the other risks.

The makers of the MFT?

Surely, you understand that let’s say you link L&N together and test with earth, as you’re passing 500v down both L&N then the potential difference is zero. So, no you would not destroy the leads.
 
The kewtech test leads allow this. The green test lead has two ports allowing you to piggy back off it. Just found some on amazon but I can’t post the link as it says I’m spamming...

IR test is 2 lead test anyways.....can’t see how joining em is gonna achieve anything ?? Kewtech do a piggy back lead for joining neutral and earth when performing Ze high current loop test....is that what you are referring to?

I get that it’s a two lead test. But watching a GSH video where they do IR test, rather than using croc clip to L&N they had this funky looking piggyback lead.

So still using 2 test leads?.....just a way of joining the cable cores together rather than crocing them?
