4.3. "ρ" MODE (Resistivity of the Earth) Geotest <strong>2016</strong> Version EN 1.01 of 19/10/2000 The measurement is taken according to CEI 64.8, IEC 781, VDE 0413, EN61557-5. Measuring procedure: Drive the 4 earth rods into the ground at the same distance D. The distance D between the rods is usually 1 to 3 meters. The distance D between the rods determines the depth at which the earth resistivity is measured. In order to identify the distance (and therefore depth) corresponding to the lowest resistivity value, the test must be repeated several times, positioning the rods at different distances. This depth will then have to be physically reached by the rods of the earth equipment. Insert the 4 connectors (black, red, blue and green) of the cables of KITTERR4C into the corresponding input terminals of the instrument (E, S, H, ES). Connect the crocodiles as shown in picture 4.
