This kit comprises of 3 items - CA6472 Earth Tester, CA6474 Tower Tester & Earth Test Probe Set

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.


  • 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

  • Dimensions: 272 x 250 x 128 mm, 3 kg

The C.A 6474 is designed for use with the C.A 6472 earth tester to measure pylon earths

When used with the C.A 6472, the C.A 6474 allows the following types of measurements:

  • Global earth of pylons
  • Earth resistance of each of the pylon's footings
  • Quality of the overhead protective earth cable connection
  • Active measurement (injection by the C.A 6472)
  • Passive measurement (use of stray currents)

Earth Probe Set

The Earth Kits are used with earth and resistivity testers implementing the 1P, 3P and 4P loop methods. 

The Earth Kits comprise 1, 2 or 4 stakes, 3 or 4 different-coloured reels of cables 50 m, 100 m or 150 m long, 1 mallet , 5 spade lug/banana plug adapters and a carrying bag. The 100 m resistivity add-on can be used to complete a 3P earth kit with 2 cable reels and two stakes. The continuity kit comprises 4 x 4 mm banana cables, 4 crocodile clips and 2 test probes.
