In short, yes. It is a test board, so there is actually fed from a board and RCD. I think the 2 cable, low test is a patent of Megger. Which prevents boards from tripping.
The Green earth lead goes in the green L2 port on the back of a Megger Multifunction tester. Other testers will he different. You do not double the value for 3 phase. The earth fault current will only travel down one of the phase cables in 3 phase, to activate the protective device. Therefore even in 3 phase, the calculated Ipf will always be 230/Zs
So im not sure why your testing pfc on the L-L L-N on the tester it should be L-PE for L to E pfc then for PSC should be L-L L-N setting both tests are 2 hi......
Which system is the electrical system grounded in?
Why did you use 2 Lo and not 2 hi, was this because you have an upstream RCD?

Where did you input the earth lead in the back of the tester for the test? also do you double this value if its 3 phase?

Is exactly what I would say...
You should change to L/N for pscc, and disconnect Rcds?
