The Chauvin Arnoux C.A 6472 earth tester is a complete portable measuring device intended for earth measurements, soil resistivity measurements and with the C.A 6474 Pylon box accessory, pylon earth measurements.
Unlike traditional earth testers, the C.A 6472 offers the possibility of analysing the frequency behaviour of earthing systems thanks to its particularly extensive measurement frequency range (from 41 to 5,078 Hz). The use of a high-frequency measurement signal makes it possible to assess the behaviour of an earthing system in the event of lightning.
The 3P method is the traditional method using rods to measure the resistance of an existing earth connection. The C.A 6472 can also be used to measure the resistances of the auxiliary rods RS and RH, as well as any interference voltages, thus allowing more accurate interpretation of the measurement.
The 4P measurement method is particularly well-suited to measuring very low earth resistance values. In the event of several resistances set up in parallel, it is possible to combine this method with a clamp-on ammeter in order to carry out selective measurements. This "4P selective" method saves considerable time as it is no longer necessary to disconnect the earth resistance to be measured.
