The DET2/3 automatic earth test instrument is designed to measure earth Electrode Resistance and Soil Resistivity, with highly accurate results. It is powered by an internal rechargeable battery which has a long usage period. Correct 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 D; for example, if D is ft, the distance value for earth resistance is x or 74 ft.
