Chauvin Arnoux P01296030 Battery pack NiMH 6 V / 8.5 Ah content_copy

This replacement battery from Chauvin Arnoux is specifically designed for the Micro-Ohmmeters of models C.A 6240, C.A 6250, and C.A 6255. It serves as a replacement battery for the integrated power supply of these measuring instruments and enables mobile operation without constant connection to a mains power source. The battery is based on Nickel-Metal Hydride technology (NiMH), providing an environmentally friendly and powerful energy source. With a nominal voltage of 6 V and a capacity of 8.5 Ah, the battery provides sufficient energy to operate the measuring devices over extended periods without requiring frequent recharging. The charging time is approximately 3 hours, ensuring the battery is quickly ready for use and minimizing operational downtime for the user.

Applications

The battery is primarily intended for use in professional measurement environments where the Micro-Ohmmeters C.A 6240, C.A 6250, and C.A 6255 are employed. These devices are used for precise resistance measurements, particularly in electrical installations, testing grounding systems, or diagnosing cable faults. The replacement battery ensures mobility and independence from stationary power sources, which is especially advantageous for field measurements or work on fixed installations.

Functions and Equipment in Detail

The battery is designed as a NiMH battery pack, offering high energy density and low self-discharge compared to other battery types. The capacity of 8.5 Ah ensures that the devices can be operated for an extended period without the battery performance dropping critically. The nominal voltage of 6 V matches the requirements of the compatible Micro-Ohmmeters, ensuring stable power supply. The charging time of approximately 3 hours is suitable for professional use, as it allows for rapid restoration of operational readiness.

Technology Explained Simply

The Nickel-Metal Hydride technology (NiMH) is a proven battery technology particularly suitable for use in measuring instruments, as it offers high cycle stability and good performance at moderate temperatures. The capacity of 8.5 Ah means that the battery can supply power for approximately 8.5 hours at a constant discharge current of 1 A – in practice, the actual operating time varies depending on load and device. The nominal voltage of 6 V is designed for the internal circuits of the Micro-Ohmmeters, so no voltage conversion is required.

Compatibility and Accessories

The battery is exclusively intended for the Micro-Ohmmeters C.A 6240, C.A 6250, and C.A 6255. When used with the C.A 6240, a reinitialization of the charge meter is required to utilize the full battery capacity. This is performed by the manufacturer’s service, requiring the device to be sent to customer service. The manufacturer recommends contacting the service when replacing the battery for the C.A 6240 to ensure correct calibration.

Installation and Mounting

The battery is inserted directly into the respective Micro-Ohmmeter, with installation accomplished by removing the old battery and inserting the new one. The devices are designed so that the battery can be replaced without tools. However, when used with the C.A 6240, the aforementioned reinitialization is necessary, which cannot be performed on the device itself but must be done in the service center.

Operational Advantages

Using this replacement battery offers high operational reliability and flexibility. The long operating time due to the high capacity of 8.5 Ah reduces the need to change the battery or connect the device to a mains power source during measurements. The fast charging time of approximately 3 hours enables efficient use, especially when performing multiple measurements in a single day. The NiMH technology ensures stable performance and low self-discharge, extending the battery’s service life.
