General
Test current	10 A

This accessory from Chauvin Arnoux consists of a set of two Kelvin test probes, specifically developed for use with CHAUVIN ARNOUX Micro-Ohmmeters and machine testers. The test probes are designed for precise measurement of low resistances, particularly in applications where contact surfaces are uneven, dirty, or covered with rust or paint layers. The retractable design of the probes ensures a secure and stable contact even on irregular surfaces, thereby improving measurement accuracy. The rotatable function of the test probes allows mechanical removal of surface contaminants such as rust, paint, or dirt, improving contact quality and ensuring reliable measurement results.

Kelvin test probes are a standard in resistance measurement technology, as they enable high measurement accuracy through separate current and voltage supply. The probes described here are designed for a test current of 10 A, making them suitable for applications with higher current loads. The connecting cables have a length of 3.15 m, providing sufficient freedom of movement for measurements at various locations. Connection is made via a removable cable lug adapter, which can optionally be converted into a 4 mm plug to increase compatibility with various measuring instruments.

The test probes are specifically designed for use with models CA 6240, CA 6250, and CA 6255, with compatibility also given for other Micro-Ohmmeters or machine testers from the brand Chauvin Arnoux. The combination of retractable and rotatable probes ensures optimal contact, even under poor surface conditions, which is particularly advantageous in industrial maintenance, machine testing, or electrical installation. Mechanical cleaning of the contact point by rotating the probes reduces error sources that could arise from oxidation or contamination.

The test probes are used directly on the measuring device, with the cable connection made via the cable lug adapter or the 4 mm plug. Installation requires no additional tools, as the probes connect directly to the device. The cable length of 3.15 m allows flexible handling, even in larger machine rooms or when testing installations not positioned directly at the device.

The operational advantages lie in the increased reliability of measurement results through mechanical cleaning of contact points and flexibility in connection type. The retractable design ensures a secure contact, even on uneven surfaces, improving measurement accuracy in practical resistance measurements. The combination of mechanical cleaning and stable contact makes these test probes a useful tool for technical personnel who need to perform precise and reproducible measurements.

Scope of delivery includes two retractable, rotatable test probes with a connecting cable of length 3.15 m and a removable cable lug adapter, which can be converted into a 4 mm plug. The test probes are intended for use with CHAUVIN ARNOUX Micro-Ohmmeters and machine testers, particularly models CA 6240, CA 6250, and CA 6255.
