Earth tester offering selective earth, soil resistivity, earth coupling and continuity measurements
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.
