The accessory set for grounding and earth resistance measurements from Chauvin Arnoux is specifically designed for use with resistance and earth testing instruments that support the 1-, 3-, or 4-wire measurement method. It enables precise determination of grounding and specific earth resistances in electrical installations and is intended for professional users in the fields of electrical engineering and safety technology. The set allows reliable and reproducible measurements under various conditions, with components tailored to the requirements of the respective measurement method.

Applications
This accessory set is used in grounding measurements to determine the resistance between a grounding point and the earth. It is suitable for testing protective and functional earthing in buildings, industrial plants, power supply networks, and during the installation of lightning protection systems. The measurement is carried out using common 1-, 3-, or 4-wire methods, with the specific configuration determined by the number of electrodes and cable reels.

Functions and Equipment in Detail
The set includes, depending on the variant, 4 electrodes, which are T-rod electrodes designed for insertion into the ground using a hammer. The electrodes serve as contact points to the earth and are essential for stable measurements. The cables are supplied in colored versions (red, blue, black, green), with colors matching the connection terminals of the measuring instruments to avoid incorrect connections. Each cable reel has a length of 150 meters, and the set contains 4 reels in total. Additionally, 5 adapters with fork terminals and banana plugs (4 mm Ø) are included to enable universal connection to various measuring instruments.

Technology Explained Simply
The use of colored cables and standardized connectors (4 mm Ø) ensures easy and error-free assignment of the cables to the measuring instruments. The cables are wound on reels, which feature handles to facilitate transport and handling. The handles can be removed to reduce space requirements during storage. The grounding electrodes (T-rod) are driven into the ground with a hammer to establish a firm connection to the earth. The adapters allow connection to devices with different connection types, regardless of whether they use banana plugs or fork terminals.

Compatibility and Accessories
The accessory set is compatible with all grounding and resistance measuring instruments from Chauvin Arnoux that support the 1-, 3-, or 4-wire method. The adapters with 4 mm Ø banana plugs and fork terminals ensure universal adaptation to various measuring instruments. Optionally, the set can be supplemented with an additional accessory set for soil resistance measurement (100 m), which includes 2 reels and 2 electrodes. This allows extension of the measurement range and more precise determination of specific earth resistance.

Installation and Mounting
Installation involves driving the electrodes (T-rod) into the ground using a hammer. The cables are connected to the electrodes and the measuring instrument, with cable colors matching the instrument’s connection terminals. The adapters ensure a secure connection. The transport bag enables comfortable transport and safe storage of all components. The bag is compartmentalized to organize and store individual parts neatly.

Advantages in Operation
The accessory set offers robust and durable equipment for professional use. The colored cable labeling reduces the error rate during wiring. The transport bag ensures organized storage and facilitates transport. The universal adapters enable use with various measuring instruments, increasing operational flexibility. The cables are designed for high mechanical load capacity to ensure reliable performance even with frequent outdoor use.
