Ergonomic, comprehensive and accurate, the C.A 6471 offers direct access to all the measurements on the front panel by means of a rotary switch. Compact because it has been designed for on-site use, the C.A 6471 is rugged and leakproof. To simplify connection, the 4 terminals for connecting the stakes are colour-coded to help identify them. The C.A 6471 includes a large backlit LCD screen and a battery which is rechargeable with an external charger connected to the mains or to a vehicle cigarette lighter. It is also equipped with a function for direct, ordered storage of the measurement results. A USB communication output can be used to export the data onto a PC in order to process them with the Ground Tester Transfer software. Specifications The C.A 6471 guarantees the reliability of measurements carried out by: traditional stake-based methods self-diagnosis when each measurement starts, so that any faults liable to affect the measurements (bad connections or presence of disturbance signals) are indicated extensive measurement ranges: 0.001 Ω to 100 kΩ adjustment of the measurement frequency between 41 Hz and 512 Hz (3P & 4P measurements) The C.A 6471 is equipped with advanced expert calculation functions: for earth coupling measurements, simply perform the 3 successive measurements required and the tester then calculates the coupling coefficient automatically for soil resistivity measurements, simply program the distances used for the measurement and the instrument automatically calculates r using the Wenner or Schlumberger methods.
