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:
    3P measurement up to 10 kΩ and stray voltages up to 60 V RMS
    4P and selective 4P measurement
    Earth loop measurement with 2 clamps from 0.01 Ω to 500 Ω
    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
    Pylon earth measurement with the C.A 6474
Other specifications:
    Storage of 512 test results
    USB optical link
    Ground Tester Transfer PC software to process the stored data
    Power supply: NiMh battery with external charger
    IP53 protection
    IEC 61557 -1 -4 -5
    IEC 61010 50V CAT IV
    Dimensions: 272 x 250 x 128 mm, 3 kg
