4 IN 1 CONTROLLER
Ergonomic, complete and precise, it offers direct access to all measurements on the front by means of a rotary switch.
Compact, designed for use on site, the C.A 6470N is robust and waterproof.
To facilitate the connections, the 4 connection terminals of the rods are identified and are of different colors.
The C.A 6470N has a large backlit LCD screen, as well as a rechargeable battery using an external charger with a mains or car outlet.
It is equipped with a direct and orderly memorization function of the results of the measurements.
A USB communication output allows data to be exported to a PC for processing with the Ground Tester Transfer software.
The benefits
The C.A 6470N offers increased precision, around 10 times higher, thanks to the 4-pole earth measurement. This method allows measurements of weak earth resistances, essential to meet the needs of energy distributors and carriers such as, in France, EDF and RTE.
The C.A 6470N guarantees the reliability of the measurements made:
by using traditional methods with picks
by means of a self-diagnosis at the beginning of each measurement, which signals the presence of possible defects that can falsify the
measurements (incorrect connections or presence of parasitic signals)
through wide measuring ranges: 0.001 Ω to 100 kΩ
by setting the measurement frequency between 41 Hz and 512 Hz
Evolved and expert calculation functions:
For the earth coupling measurement, it is enough to successively carry out the 3 necessary measurements and the controllers automatically calculate the coupling coefficient
In soil resistivity measurement, programming the distances used for the measurement allows the instruments to automatically calculate r using the Wenner or Schlumberger methods.
