FLUKE 1630 earth resistance tester Ground earth tester clamp earth tester F-1630 clamp resistance tester

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 parellel grounds, as well as the process of finding suitable locations for auxiliary ground stakes.  You can also perform earth ground tests in places you have not considered before:  inside buildings, on power pylons or anywhere you don't have access to soil.With the Stakeless testing method, the Fluke 1630 Earth Ground Clamp Meter is placed around the earth ground rod or the connecting cable.  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.  Gone are the days of spending time placing and connecting stakes for each ground rod on your system - a major time saver.What's Included:
