5-in-1 earth and resistivity tester

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 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 6470N & C.A 6471 guarantee the reliability of measurements carried out with:
  - 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
  - large measurement ranges: 0.001 W to 100 kW
  - adjustment of the measurement frequency between 41 Hz and 512 Hz

* The C.A 6470N & C.A 6471 are equipped with sophisticated calculation functions:
  - for earth coupling measurement, all you have to do is carry out the 3 measurements
   necessary, one after the other, and the testers then calculate the coupling coefficient
   automatically
  - when measuring soil resistivity, the distances used for the measurement can be
   programmed to allow the instruments to calculate r automatically with the Wenner or
   Schlumberger methods.
   rogramming of the distances used for the measurement makes it possible to calculater
   automatically by the Wenner or Schlumberger methods.
