Chauvin Arnoux CA6472 Earth and Resistivity Tester
The Chauvin Arnoux CA6472 Earth and Resistivity Tester is a highly sophisticated instrument that can perform a full range of earth and ground tests: soil resistivity (Wenner and Schlumberger models), earth coupling, ground potential measurement, and continuity/resistance (two-wire or four-wire). A range of different measurement techniques can be used with the tester including three-pole, four-pole, four-pole selective and earth loop measurement with two clamps. The tester’s resistance range varies depending on the measurement technique used but the largest possible range is 0.01Ω to 99.9kΩ and ground voltage can be measured between 0.01mV to 65V. A very large frequency test range (41Hz to 5078Hz) allows the user to test the performance of earthing structure should the system be struck by lightning.
Two different operating modes make the Chauvin Arnoux CA6472 an ideal instrument for both experts and less experienced users. Automatic mode allows tests to be triggered with a single button after being selected via the simple rotary switch. The default test is executed at 128Hz but the tester will choose the most appropriate frequency in the event of interference voltages. Accuracy is aided by the tester’s capacity to reject interference voltage up to 60V. In Expert mode, the user can select specific measurement parameters (frequency, frequency scan, voltage etc.) and access additional readings to help interpretation and analysis.
Setting up the Chauvin Arnoux CA6472 for testing is aided by colour-coded terminals and intuitive operation as well as a useful information sheet in the lid of the tester. Additionally, the tester has automatic input recognition which alerts the user if the corrections are incorrect or missing, thus aiding safety and accuracy. Up to 512 test results can be stored on the instrument’s internal memory and then transferred to a PC via the supplied USB cable where Chauvin Arnoux DataView software helps to analyse and decode the figures.
The Chauvin Arnoux CA6472 has IP53-rated casing which helps keep it dry and secure when working in the field, as well as keeping the user safe in dangerous or noisy environments. It comes supplied with a mains adapter and cable for recharging the battery, data export software, a USB cable and two C182 clamps whilst a 12-month warranty is supplied by the manufacturer.

Chauvin Arnoux CA6474 Adaptor for Pylon Earth Measurements
An impressive function of the Chauvin Arnoux CA6472 is its ability to carry out testing on pylons with earth cables when working in tandem with the Chauvin Arnoux CA6474 Adaptor for Pylon Earth Measurements. Earthing is a very important part of pylon structure as it allows lightning to discharge safely to earth without affecting the high-voltage line. This test function means that the earth cable on a pylon need not be disconnected when testing earth resistance which is both safer and faster. By attaching 4 current sensors to the feet of the pylon, the tester and adapter work together to determine the earth impedance of the structure precisely and selectively, thanks to the large frequency range of the CA6472. By using the two devices together, measurements can be acquired for parameters including overall earth resistance of the line, resistance of the pylon under test, resistance of each pylon foot and resistance of the earth cable between the pylons.
