This test accessory from Chauvin Arnoux consists of a 10 m long test lead in green colour, wound on a compact reel. It is specifically designed for precise measurement of earth resistance and specific earth resistances. The green colour coding serves for clear identification of the cable in measurement applications, particularly in the context of earthing and resistance measurements. The robust design ensures reliable performance and long service life during regular use in professional environments, such as electrical installations or field operations.

Test lead on reel enables easy handling and storage. The compact winding on the reel reduces the risk of tangling or injuries caused by loose cables and facilitates transport and storage. The cable is designed for use with earth resistance measuring instruments supporting the 1-, 3- or 4-wire method. In combination with additional accessories such as earth electrodes or adapters, the device can be used for comprehensive earthing measurements.

Applications include testing of earthing systems in buildings, industrial facilities, and in the field of electrical installation. The test lead serves as a connecting element between the measuring instrument and the earth point or the earth element to be tested. The green colour is conventionally used in electrical engineering for earthing conductors, simplifying identification in the measurement setup.

Functions and equipment in detail include a durable, robust construction designed for professional use. The reel is dimensioned to compactly accommodate the entire 10 m long cable without damaging or excessively stressing the cable. The green colour is not only visually identifiable but also complies with common standards for marking earthing conductors.

Technology explained simply shows that the cable functions as part of a measuring system that measures electrical conductivity between earth points or between an earth point and ground. The reel serves purely as a mechanical aid for organising and transporting the cable. The cable itself is not equipped with additional electrical functions such as filters or impedance matching, but serves as a pure connecting cable section.

Compatibility and accessories include use with earth resistance measuring instruments supporting the 1-, 3- or 4-wire method. These components can be used additionally to build complete measuring systems for different application cases.

Mounting and installation require no special tools. The cable is directly connected to the corresponding terminals of the measuring instrument and the earth point. The reel is unwound during measurement and rewound after measurement, ensuring quick and safe handling.

Operational advantages lie in easy handling, clear colour coding, and robust construction. The compact reel reduces space requirements and prevents tangling during storage. The green colour simplifies identification in the measurement setup, especially in complex arrangements with multiple cables. The cable is designed for professional use and suitable for repeated measurements in various environments.

The product is delivered as a single unit: 1x 10 m test lead on small reel (green).
