Nulling Test leads

[Risteard]

As above, Fluke has this where you null leads for loop testing.

Megger does not.

However the newer Meggers (e.g. 1700 series) have an option in the settings to adust lead resistance. I think the default's something like 0.07 Ohms for a standard lead set, but this may need to be altered for fused leads etc.)

Sorry this is not related to live loop testing but your post made me think about the 1700 series..

I hate the 1700s for the way they do not display negative values. The 1552 and. It's ilk were much better in that way and you could easily and confidently do simple maths to get end to end values etc without endless button pressing.. also those blo0die silicone leads... gggggrrrrrrrr!!

I've never used a meter where nulling the leads on a loop test was possible.
