Tester for all types of earth measurements, including pylon earth measurements (with the C.A 6474) - soil resistivity - earth coupling - ground potential - continuity & resistance
The C.A 6472 can be used for quick, comprehensive surveys of all earthing configurations, offering all the necessary earth measurement functions in a single instrument.
When used with the C.A 6474, it can also perform pylon earth measurements, making it a unique but essential tool for diagnostics and maintenance on pylon networks.
The C.A 6472 offers the possibility of analysing the frequency behaviour of the earth connections thanks to its extensive measurement frequency range (41 to 5,078 Hz).
The use of a high-frequency measurement signal makes it possible to assess the behaviour of an earthing circuit in the presence of lightning.

Functions:
Earth coupling measurement
Soil resistivity measurement: simply program the distances used for the measurement and the tester then calculates r using the Wenner oe Schlumberger methods
Ground potential measurement
Continuity and resistance measurement
