Earth/Ground Tester Operation RA 3-Pole Selective Earth Resistance Measurement with Current Clamp The RA 3-pole Selective Earth Resistance Measurement with Current Clamp procedure is useful for the resistance measurement of different parallel sections of an earth/ground system. 1. Select 3 POLE . See Figure 6. 2. Connect test leads. Connect the supplied test lead (1.5 m) to terminal E/C1 and its other end to the ground system to be measured. Place two ground stakes in earth/dirt. Minimum distance between earth electrode (E/C1), probe (S/P2) and auxiliary earth (H/C2) should be at least 20 m. Connect stakes with 25 m and 50 m wires to H/C2 and S/P2 as shown. Connect current clamp with adapter cable as shown. 3. Push START.  indicates that measurement is in progress. For continuous measurement, continue to push the START button. 4.  indicates completed measurement.
