Earth tester method
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 … 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.
