I've been looking into these meters. How exactly do they work? I have not found any good documentation explaining how it is possible to check the resistance of a ground rod by simply clamping around the conductor.
The really puzzling part is that you don't need to disconnect the secondary ground (ie: water pipe) to measure the resistance of the ground rod to earth.
Any thoughts? Any links to good articles?
FYI I am looking at the Amprobe DGC-1000 and the AEMC 3711.
Links to both meters are below.
