WebCorrect earth resistance is read from the curve for the distance that is about 62 percent of the total distance from the earth electrode to C. In other words, if the total distance is D, the 62 percent distance is 0.62D; for example, if D is 120 ft, the distance value for earth resistance is 0.62 x 120 or 74 ft.
