WebAn earth resistance tester is connected to these four stakes. The DC test option on the tester is then selected and performed, and the resistance figure R recorded. The soil resistivity level r in ohms/cm is then found out using the formula: r = 2 ρaR where: R = the resistance figure (in ohms), a = the separation of the test stakes, in metres. WebThe Fluke 1625 earth ground tester is able to measure earth ground loop resistances for multi-grounded systems using only current clamps. 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 ground stakes.
