The 4P measurement method is more accurate and can be used to measure low earth resistances. The results obtained with this measurement method are ideal for the requirements of energy distributors such as EDF. EARTH LOOP MEASUREMENT WITH 2 CLAMPS In the event of a system with parallel earth connections, 2 clamp-on ammeters can be used with the C.A 6470N & C.A 6471 to provide accurate earth resistance measurements. The principle of this method involves placing 2 clamps around the earth conductor tested and connecting each of them to the instrument. One clamp injects a known signal (32 V / 1,367...
