This product is a current clamp AC C182, specifically developed for the earth and earth resistance meters C.A 6471 and C.A 6472 by Chauvin Arnoux. It serves as a replacement part and extends the functionality of these measuring instruments by enabling selective earth measurements using a clamp and spikeless earth measurements using two clamps. These measurement methods are particularly advantageous in electrical installation and maintenance, as they eliminate the need for earth spikes and thus reduce time and effort.

Applications
This accessory is designed for professionals in the field of electrical installation and maintenance who need to perform precise and efficient earth measurements. The ability to carry out earth measurements without additional spikes is especially useful in environments with limited space or sensitive installations. The spikeless method also allows for faster and less disruptive measurements, as no drilling or puncturing of the ground is required.

Functions and Equipment in Detail
The current clamp AC C182 supports selective earth measurements, allowing individual conductors or earth leads to be measured separately. This is important for accurately checking the earthing of individual devices or installations. Additionally, it enables spikeless earth measurements using two clamps, allowing earth resistance of installations to be determined without physical earth spikes. This method is particularly beneficial for existing installations or in sensitive environments.

Technology Explained Simply
The clamp is designed for alternating currents up to 40 Aeff, making it suitable for use in typical electrical installations. The construction is designed for larger conductor diameters, allowing it to be used even with thicker cables or conductors. The technology is based on a current transformer principle, where the current to be measured passes through the clamp and the measurement value is detected via a magnetic field. This enables contactless measurement without interrupting the power supply.

Compatibility and Accessories
This accessory is exclusively compatible with the earth and earth resistance meters C.A 6471 and C.A 6472. It is not a universal accessory, but specifically developed for these devices to extend their measurement functions. Use with other measuring instruments is not intended and is not supported.

Mounting and Installation
Installation is carried out by simply placing the clamp around the conductor to be measured. The clamp is closed over the conductor, ensuring that the clamping connection is secure and stable to guarantee reliable measurement. The operating instructions, included in the delivery, describe the correct handling and necessary preparations for the measurement.

Operational Advantages
The use of the current clamp AC C182 offers high flexibility and time savings when performing earth measurements. The ability to measure without earth spikes reduces workload and disturbance to the environment. The support for larger conductor diameters expands the range of applications and makes the accessory suitable for a wide variety of use cases. Precise measurement enables reliable assessment of earthing quality and contributes to the safety of the electrical installation.
