The Fluke 16302FC Stakeless Earth Ground Loop/AC Leakage Current Clamp with Fluke Connect Compatibility, 1000V AC is the kind of high-quality, rugged tool you expect from Fluke; its heavy-duty clamp jaw stays in alignment and in calibration even in every day, on-the-job industrial environments.

Test the grounding components of equipment in hard-to-reach spaces, including areas that are indoors or fully paved and do not permit driving auxiliary test stakes. Stay online-identify ground loop resistance without the need to disconnect, then reconnect the earth electrode from the system.

The 1630-2 FC clamp measures earth ground loop resistances for multi-grounded systems using the dual-clamp jaw. This test technique eliminates the dangerous and time-consuming activity of disconnecting parallel grounds, as well as the process of finding suitable locations for auxiliary test stakes. You can also perform ground tests in places that were previously difficult: inside buildings, on power pylons or anywhere where you do not have access to soil for auxiliary test stakes.

With this test method, a two-process measurement is made around the earth ground wire or bus bar using the specially designed jaw of the 1630-2 FC clamp. Auxiliary test stakes are not used at all. A known voltage is induced by the source in the clamp, and the current is measured by the sensor in the clamp. The tester automatically determines the earth loop resistance for this section of the earthing system.
