Fluke 1623-2 Earth Ground Tester performs all four ground tests quickly and accurately. The Fluke 1623-2 earth ground tester measures earth ground loop resistances using only clamps, only stakes, or one clamp and stakes. With the stakeless test method, the Fluke 1623-2 is able to measure earth ground loop resistances for multi-grounded systems using only current clamps. This technique eliminates the dangerous, and time consuming job of disconnecting parallel grounds, and finding suitable locations for auxiliary ground stakes. You can use it to perform earth ground tests in places you’ve not considered before, such as inside buildings, on power pylons, or anywhere you don’t have access to soil.
