Earth and Resistivity Tester Chauvin Arnoux C.A 6470N TERCA 3

Description

Ergonomic, comprehensive and accurate, the C.A 6470N 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 6470N is rugged and leakproof.

To simplify connection, the 4 terminals for connecting the stakes are colour-coded to help identify them.

The C.A 6470N 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.

Features

The C.A 6470N 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 6470N is equipped with advanced expert calculation functions:

- for earth coupling measurements, simply perform the 3 succesive 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.
