Web2. Soil Resistivity Measurement Experimental Procedure Current flow through the earth is a necessary condition for measuring soil resistivity. This may happen only by driving vertical rods into the ground, supplied with electric current. Therefore, numerous techniques have been developed and proposed in the international literature, applied WebTo measure the soil resistivity start the Fluke 1625 and read the resistance value in ohms. In this case assume the resistance reading is 100 ohms. So, in this case we know: A = 3 meters, and. R = 100 ohms. Then the soil resistivity would equal: r= 2 x p x A x R. r = 2 x 3.1416 x 3 meters x 100 ohms.
