WebMay 22, 2024 · One of these alternative methods is variation of depth, or the three-point method. Here, ground resistance measurements are repeated in correlation with incremental increases in ground rod depth. This technique forces more test current through deep soil, and changes in resistivity can be noted at each depth. 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.
