Fluke 1630 Earth Ground Clamp Meter
Safely measures ground loop resistance
The Fluke 1630 Earth Ground Clamp Meter is able to measure ground loop resistances-using the stakeless testing method. This test technique eliminates the dangerous, and time consuming activity, of disconnecting parallel grounds. You can also perform earth ground tests: inside buildings, on power pylons or anywhere you don't have access to soil.

With the stakeless testing method, no earth ground stakes are used at all. A known voltage is induced by one half of the clamp and the current is measured by the other half. The tester automatically determines the ground loop resistance at this grounding connection.
