[RE-wrenches] clamp on ground impedance tester

[R Ray Walters]

I bought the Amprobe DGC-1000A. I paid around $1000, but I see they've gone up a bit already. I can't necessarily recommend (or berate) the web biz I bought it from, so I'm not going to give them a plug.
I'd just google: the make & model #.
The Amprobe is very easy to use, but the 2 down sides are:
1) It cannot be used for off grid systems, as it depends on the grid for its reference.
2) It can be hard to get the jaws in tight spots, so you need about 2" of exposed ground rod or wire, with 2" of clearance in a radius around it.
(another reason to leave the ground rod sticking out of the ground a few inches)
