Introducing the Chauvin Arnoux CA 6471 Earth Resistance Meter

The CA 6471 integrates many essential measurements into a single device, making field measurements more convenient and easier to control..

Measurement function of CA 6471

CA 6471 supports three main measurement groups commonly encountered when testing grounding systems.

The device allows for three-pole and four-pole earth resistance measurements, suitable for various terrain conditions. In addition, the CA 6471 supports earth resistivity measurement, aiding in the surveying and design of grounding systems from the initial stages. Furthermore, the continuity test function allows for quick assessment of the grounding system's connection status.

Thanks to the integration of all necessary measurements, users do not need to carry multiple devices when working in the field.

Design and usability

The CA 6471 boasts a robust design, suitable for outdoor work environments and engineering projects. Its compact size makes it easy to carry when moving between measurement points.

The probes and connection ports are clearly color-coded, facilitating quick and easy connection and minimizing errors. The backlit LCD screen allows for easy viewing of measurement results even in low-light conditions. The integrated rechargeable battery provides flexibility for field use and can be recharged via an external power source or battery.

What is its stability, measurement range, and ports?

The CA 6471 uses a four-pole measurement method, supporting the measurement of very low earth resistance values, meeting the requirements for testing the grounding systems of power substations, factories, and engineering structures. Its wide measurement range from 0.001 ohm to 100 kiloohm makes the device suitable for various terrains and soil conditions.

The device allows for the selection of the appropriate measurement frequency, reducing the influence of interference and improving the stability of the measurement results. Before each measurement, the system automatically checks the connection status and measurement environment, thereby providing early warnings of factors affecting the results.

The CA 6471 is equipped with a USB port, allowing data to be exported to a computer for storage and processing. The Ground Tester Transfer software supports the aggregation of measurement results, facilitating the creation of technical reports and the archiving of grounding system inspection records.

This feature is particularly useful for construction companies, technical consultants, and electrical system maintenance firms that need to manage measurement data for each project.

Practical applications of CA 6471

The Chauvin Arnoux CA 6471 earth resistance meter is suitable for testing grounding systems in substations, manufacturing plants, industrial parks, construction sites, and lightning protection systems. The device effectively meets the needs for initial surveys as well as periodic testing after operation.

Currently, the CA 6471 is one of the specialized earth resistance meters distributed by EMIN, suitable for technical units requiring a stable, easy-to-use measuring device that fully meets the necessary measurement requirements for grounding systems.
