How to do ze test with meger.

[shocksl]

Hey guys

I've got my megger mft1722.

I'm trying to do the live Ze and Zs tests.

So for example I know to do my Ze test use a croc on incoming earth via disconnecting it first. And use a line probe on incoming line.

However I'm unsure as all my probes are colour coordinated (fused and unfused ive tot both). I have all 3 probes but for this I just the need the 2.

Too do the first test . I googled It says put my probe wires in red l1 and blue r3. However should I just be putting red probe in l1 for live and green croc wire in in the green l2 in my test meter?

Thanks for any help. Also for this test do I need to to do the neutral as well.

Have you set it to two wire high current?
