Chauvin Arnoux P01102087 Power adapter for MiniFLEX MA200 content_copy

This accessory from Chauvin Arnoux is specifically designed for the Micro-Ohmmeters models C.A 6250 and C.A 6255 and supports precise resistance measurements on materials with high temperature coefficients. The core function is to automatically convert the measured resistance value into a temperature-compensated value, thereby minimizing the impact of ambient temperature fluctuations on measurement accuracy. This function is particularly important in industrial and technical applications where measurement results must remain consistent and reproducible under variable environmental conditions.

Applications
This accessory is used when measuring materials whose electrical resistance is highly dependent on temperature, such as copper or aluminium conductors. In electrical installation, machine building, or testing of connection points in power supply systems, temperature-compensated measurement is necessary to determine the actual resistance values under standard conditions (e.g. 20 °C). This enables a more objective assessment of the electrical quality and safety of connections.

Functions and Equipment in Detail
The accessory enables the Micro-Ohmmeters C.A 6250 and C.A 6255 to correct the measured resistance value based on the current temperature of the material. The calculation is performed automatically once the accessory is activated, eliminating the need for manual correction by the user. The function is specifically designed for materials with high temperature coefficients, where minor temperature changes can cause significant resistance variations. This increases measurement accuracy and ensures results are independent of short-term temperature fluctuations in the measurement environment.

Technology Explained Simply
The temperature coefficient describes how strongly the electrical resistance of a material changes with temperature. This effect is pronounced in materials such as copper or aluminium. Without compensation, a measured resistance value could be incorrectly interpreted as too high due to elevated ambient temperature, even though it would be acceptable under normal conditions. The accessory integrates temperature data into the calculation, converting the displayed value to a reference temperature (typically 20 °C). This is especially important for tests where resistance values are used to assess connection reliability.

Compatibility and Accessories
The accessory is compatible exclusively with the Micro-Ohmmeters C.A 6250 and C.A 6255. It is not recommended or supported for use with other devices or models from Chauvin Arnoux. Using it with other measuring instruments will result in no functionality. The operation is tailored to the internal algorithms of these specific devices.

Installation and Mounting
Installation is carried out by connecting the accessory to the respective Micro-Ohmmeter. No additional tools or settings outside the device functions are required. Activation of temperature compensation is performed via the Micro-Ohmmeter's user interface.

Operational Advantages
Temperature-compensated resistance calculation increases the reliability of measurement results. Users receive consistent values regardless of current ambient temperature, simplifying result interpretation. This reduces error susceptibility when assessing electrical connections and supports compliance with quality standards in electrical installation and industrial operations. The automatic calculation saves time and avoids manual corrections.

The delivery includes the temperature compensation accessory and an operating manual. Further details about the accessory are available upon request.
