Chauvin Arnoux P01295264 Spool with 100 m test lead blue content_copy

This test accessory from Chauvin Arnoux consists of a 100 m long test cable in blue colour, wound on a reel. The reel is equipped with a handle to facilitate transport and handling during measurement. The product is specifically designed for measuring earth resistance and specific earth resistances, and serves as a supplement to earth resistance measuring instruments operating according to the 1-, 3- or 4-wire method. The cable colour corresponds to the connection terminals of the manufacturer's measuring instruments, preventing connection errors. The cable length is adapted to typical applications associated with the manufacturer's earth resistance measuring kits.

Applications
This accessory is used in the fields of electrical engineering and safety technology, particularly for testing earthing systems in buildings, industrial plants or outdoors. It is suitable for measurements using the 3- or 4-wire method, where earth resistances must be precisely determined. The use of specific earth resistance measurements also allows analysis of soil conductivity, which is important when planning earthing systems or verifying the effectiveness of existing systems. The blue colour of the cable serves for clear assignment to specific measurement points or connection terminals.

Functions and Equipment in Detail
The test cable is wound on a reel equipped with a handle. This handle enables secure holding and transportation of the reel, especially during installation in the field. The reel itself is designed to neatly accommodate the cable and prevent tangling during transport or use. The cable is blue in colour, enabling clear visual distinction from other cables, for example those in green or black. The length of 100 m is sufficient for many standard applications, especially when measurements are carried out over longer distances.

Technology Explained Simply
The test cable serves as a connecting element between the earth resistance measuring instrument and the earthing points or measurement points in the ground. When measuring earth resistance, the cable is laid between the instrument and the earth electrode, with the cable length determining the measurement range. The blue colour is not a technical factor but serves to assign the cable to specific connection terminals on the measuring instrument, avoiding confusion. The reel with handle facilitates handling, especially with longer cables that must be laid in the field.

Compatibility and Accessories
The accessory is compatible with all earth resistance measuring instruments from Chauvin Arnoux, regardless of the type of connectors, as the instruments are equipped with adapters featuring 4 mm Ø banana sockets or fork connectors. It can be used as a supplement to existing measuring kits, particularly for 3- or 4-wire measuring systems. Additional accessories also offered include, for example, a set of 5 adapters (cable lugs / 4 mm banana socket), a set of 4 handles for reels, a T-shaped earth electrode, and a reel with 150 m test cable in red. These components can be combined according to requirements to create a complete measuring kit.

Installation and Mounting
Installation is carried out by winding the cable onto the reel, which is already equipped with a handle. The cable is connected to the appropriate terminals on the measuring instrument, with the cable colour (blue) serving for assignment. The reel can be held during installation to guide the cable. The cable is then routed across the terrain and connected at the earthing point or measurement point. Handling is facilitated by the handle, especially over longer distances. After use, the reel can be stored, and the handle can be removed to optimise storage space.

Advantages in Operation
The use of this test cable provides clear and error-free assignment through uniform colour coding, matching the connection terminals of the measuring instruments. The reel with handle ensures easy handling and portability, making field operations more efficient. The length of 100 m enables measurements over longer distances, which is advantageous when testing earthing systems in large buildings or industrial plants. The high quality of the cable ensures reliable measurement results and a long service life.
