Chauvin Arnoux CA6470N TERCA 3 Earth & Resistance Tester

Buy Chauvin Arnoux CA6470N TERCA 3 Earth Tester

The CA6470N TERCA 3 Earth and Resistance Tester is an ergonomic, complete, and accurate 4-in-1 earth, resistance, coupling, and continuity tester. The CA 6470N TERCA 3 uses both 3-pin and 4-pole land surveying methods. 4-pole measurements are approximately 10 times more accurate and allow for low-resistance ground measurements.

These specialized measurements are essential to meet the needs of power distribution and transmission companies and power distributors such as EDF. The 6470 TERCA 3 offers a wide measurement range between 0.001 Ω and 100 kΩ and a matching frequency between 41 Hz and 512 Hz. The C.6470 earth resistance and earth resistance tester ensure reliable measurements by using traditional stake-based methods.

This ground-to-ground tester performs self-diagnostics before starting each measurement to detect errors that can cause measurement errors. There are also high-level and expert calculation functions provided automatically by Earth Tester.
