This test lead from Chauvin Arnoux is a high-quality accessory for measuring earth resistance and specific earth resistances. The product consists of a 100 m long cable wound on a reel with a handle to facilitate transport and handling. The cable is green, which is commonly used in electrical engineering for earthing cables and thus provides clear visual identification.

Applications
The test lead is specifically designed for use in earthing systems, particularly for testing 3-pole and 4-pole earthing sets. It serves as a connecting element between the measuring device and the earthing systems or electrodes to perform precise resistance measurements. The length of 100 m provides sufficient reach for larger installations or for measurements where the earthing electrodes are distributed over greater distances.

Functions and Equipment in Detail
The cable is wound on a reel with a handle, ensuring compact storage and easy transport. The handle facilitates unwinding and rewinding the cable, especially over longer measurement distances. The green colour of the cable corresponds to the international marking for earthing cables and supports clear identification during use.

Technology Explained Simply
The test lead serves as a connecting element between the earth resistance measuring device and the earthing electrodes. When measuring earth resistance, current is conducted through the cable to one or more earthing electrodes while the voltage drop is measured. The length of 100 m allows sufficient coverage of installations without requiring additional extensions. The green colour is a visual indicator commonly used in the electrical trade to distinguish earthing cables from other cables.

Compatibility and Accessories
The cable is designed for use with earthing sets, particularly for 3-pole and 4-pole arrangements. It is used as an accessory for earth resistance measuring devices, although specific compatibility with particular devices from the brand Chauvin Arnoux is not specified. The cable is used in combination with earth resistance measuring devices that have appropriate connections for test leads.

Installation and Mounting
Installation is carried out by connecting the cable to the measuring device and then to the earthing electrodes. The reel allows for orderly unwinding of the cable, thereby avoiding tangling and damage.

Operational Advantages
The wound reel with handle ensures compact and portable storage. The length of 100 m provides sufficient reach for many applications in earth resistance testing. The green colour supports clear identification of the cable during use, enhancing work safety and preventing incorrect connections. The cable is designed as robust test accessory suitable for use in professional testing applications.
