Megger 1721 Zs explained please

[bhamoggy]

I use a Megger MFT 1720; there are three options for testing earth loop impedance: 2Hi, 2Lo, 3Lo.
Can anyone explain the different variants as I get different readings depending which option I choose
Thanks

This is a wild guess
2 wire Hi current
2 wire Lo current
3 wire Lo current

First one prob trips RCDs


If only there were some way that the manufacturers could put the correct useage of their instruments onto paper and make them available to anyone who had......whoaaa hang on a minute
