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

The C.A. 6470N TERCA 3 Earth and Resistivity Tester is an ergonomic, comprehensive and accurate 4 in 1 earth, resistivity, coupling and continuity tester. The CA 6470N - TERCA 3 employs both 3-pole and 4-pole methods of measuring the earth. The 4 pole measurements offer approximately 10 times greater accuracy and allows low earth resistance meaurements. These measurements in particular are essential to meet the requirements of power distribution and transmission companies as well as energy distributors such as EDF. The 6470 TERCA 3 provides an extensive measurement range of between 0.001Ω and 100kΩ and an adjustment frequency of between 41Hz and 512Hz. The C.A. 6470 earth & resistivity tester guarantees reliable measurements through the use of traditional stake-based methods. This ground earth tester will self diagnose before starting each measurement to detect any faults that may cause measurement errors. There are also high-level and expert calculation functions automatically provided by the C.A. 6470N Earth & Resistivity tester. For the earth coupling measurement, simply perform the 3 successive measurements required and leave the tester to calculate the coupling coefficient automatically and when measuring soil resistivity, programming of the distances used for the measurement makes it possible to calculate r automatically by the Wenner or Schlumberger methods.

The CA 6470N tester offers direct access to all the measurements via a rotary switch on the front panel and its compact, rugged and leakproof design is perfect for use in the field. To simplify the connections, the 4 terminals for connection to the stakes are colour-coded. The C.A 6470N includes a large backlit LCD screen and a rechargeable battery with an external charger for connection to the mains supply or to a vehicle cigarette lighter. It is equipped with a function for direct, ordered storage of the measurement results. A USB communication output allows the data to be exported onto a PC with the Ground Tester Transfer software for further processing.
