Chauvin Arnoux CA 6470N [P01126506] TERCA 3 Earth and Resistivity Tester

This ergonomic, complete with high accuracy measuring device, all measurements over a built-in rotary switch can be set in the operator panel. The robust and shock-proof C.A 6470 N is compact and suitable for use in the field. The connection of the earth was by a color marking of the terminals is simplified. The C.A 6470 N has a illuminated LCD-display and a rechargeable battery via the external to the network or a cigarette lighter socket of a vehicle attached battery charger can be charged. It is equipped with a function for automatic or manual storage of the measured values.
Via a USB output, you can transfer data with the Software Ground Tester be transferred to a computer for processing.

The C.A 6470 N offers thanks to the measurement with the 4-Pol-Verfahren up to 10 times higher accuracy. Use this procedure to lower the earthing resistance can be measured and it is thus especially for industrial users, e.g. Energy suppliers, suitable.

The C.A 6470 N provides guarantees reliable measurements:
Through the use of classical measuring procedure with earthing rods
By a self-diagnosis before each measurement, for which possible errors (bad connection or interference signals), which can lead to incorrect measurements are displayed
By large measuring range: 0.001 Ω to 100 kΩ
With a setting of measurement frequency between 41 Hz and 512 Hz

Calculation Functions for experts:
For the calculation of the erdkopplungswiderstands are simply the three necessary measurements carried out and the device automatically calculates the coupling coefficients
For the calculation of the specific soil resistance. The programming of the measuring distances enables automatic calculation of R after the Wenner method or the schlumberger procedures.
