Chauvin Arnoux P01102047 charging station for Li-Ion battery content_copy

This product is an accessory for the Micro-Ohmmeters C.A 6250 and C.A 6255 by Chauvin Arnoux, specifically developed for precise resistance measurements on materials with a high temperature coefficient. It enables the calculation of the temperature-compensated resistance, thereby increasing measurement accuracy by reducing the influence of temperature fluctuations on the conductivity of the materials. This is particularly important in industrial applications, where measurement results must remain reliable even under varying environmental conditions.

Applications
This accessory is used when measuring materials whose electrical resistance is highly dependent on temperature, such as copper or aluminum conductors. In industrial electrical engineering, during testing of connection points, switchgear, or transformers, accurate resistance measurement is crucial for assessing the quality and safety of connections. Temperature compensation ensures that measured values are converted to a standardized reference temperature, ensuring comparability of measurements over time and location.

Functions and Equipment in Detail
The main function of the accessory is the calculation of the temperature-compensated resistance. The measured resistance value is corrected based on the current temperature of the material to determine the actual resistance at a defined reference temperature (e.g. 20 °C). This is particularly relevant for materials with a high temperature coefficient, as their resistance varies significantly with temperature changes. Integration with the Micro-Ohmmeters C.A 6250 and C.A 6255 is achieved via existing interfaces, with the measuring instruments receiving the necessary data for calculation.

Technology Explained Simply
The temperature coefficient describes how strongly the electrical resistance of a material changes with temperature. In metals such as copper, resistance increases with rising temperature. Without compensation, measurements on a hot or cold conductor could lead to incorrect conclusions. The accessory ensures that measurement values are converted to a standard value regardless of the material’s current temperature. This increases measurement reliability, especially for repeat measurements or monitoring wear and corrosion at electrical connections.

Compatibility and Accessories
The accessory is exclusively compatible with the Micro-Ohmmeters C.A 6250 and C.A 6255. It is offered as an extension for these devices to enhance their functionality for specific measurement tasks. Use is directly in conjunction with the specified measuring instruments.

Installation and Mounting
Installation is performed by connecting the accessory to the appropriate interfaces of the Micro-Ohmmeters C.A 6250 or C.A 6255. The operating instructions serve as guidance for correct use and integration into the measuring device.

Operational Advantages
Using the accessory leads to significantly improved measurement accuracy, especially for materials whose resistance is temperature-dependent. This enables more precise assessment of electrical connections and reduces the likelihood of misinterpretation. Results are comparable regardless of current ambient temperature, increasing efficiency for repeat measurements and documentation of conditions. Integration into existing Micro-Ohmmeters requires no additional hardware, simplifying handling.

Scope of Delivery
The product is delivered with the temperature compensation accessory and an operating instruction manual.
