The item is a test lead set from the brand Chauvin Arnoux, specifically designed for use with insulation testers CA 6541 and CA 6543. It is a cable set with a length of 1.5 meters, consisting of three individual leads: one red, one blue, and one shielded black lead. The leads are intended for performing insulation tests and voltage measurements in industrial and residential environments, particularly during maintenance and testing of electrical installations, cables, motors, RCDs, and transformers.

Applications
This cable set is designed for use in power and telecommunications networks. It is particularly suitable for testing the compliance of electrical installations with applicable standards, with measurements able to be carried out both indoors and outdoors. The leads are designed for use with portable, compact insulation testers used on construction sites or in workshops.

Functions and Equipment in Detail
The three leads in the set are each 1.5 meters long and feature straight plug connectors at both ends. The red and blue leads are used for connecting to the test instruments, while the black shielded lead serves as a reference or earth lead. The use of shielded leads minimizes interference from electric fields and ensures precise measurement. The color coding facilitates correct assignment of the leads during testing.

Technology Explained Simply
The leads are designed for use with analog insulation testers that generate a stable test voltage via an inductor. The test instruments compatible with this set operate without external power sources such as batteries or power supplies, instead using magnetic induction to generate the required voltage. The test instruments are designed for test voltages of 250 V, 500 V, and 1000 V DC, with insulation resistances measurable in the range of 1 to 5000 MΩ. The accuracy of insulation measurement is 2.5 % of full scale, while voltage measurement (up to 600 Vac, frequency range 45 to 450 Hz) is performed with an accuracy of 3 % of full scale. The display is analog, enabling quick visual assessment of the measured values.

Compatibility and Accessories
The cable set is specifically developed for the CA 6541 and CA 6543 models from Chauvin Arnoux. These components can be purchased additionally to enhance the safety and transport of the devices when used with the test lead set.

Installation and Mounting
The leads are mounted by simply plugging them into the corresponding sockets on the test instrument. The leads are designed for direct connection to the test objects, with the color coding (red, blue, black) supporting correct assignment. No additional tools or mounting aids are required.

Operational Advantages
The cables are robust and designed for use in construction site and workshop environments. The 1.5-meter length provides sufficient mobility during testing without being excessively long. The use of shielded leads ensures high measurement accuracy, especially in electromagnetically noisy environments. Compatibility with analog insulation testers powered by an inductor enables independent, mobile use without a power supply.

Protection Rating and Safety
The test instruments with which this set is used have a protection rating of IP 54 when the cover is installed, and IP 52 without the cover. This means the instruments are dust-protected and protected against splashing water, making them suitable for outdoor use. Electrical safety complies with the standard CEI 61010, with a category of 600 V CAT II and 300 V CAT III, allowing use in electrical installations with corresponding voltage categories.

Scope of Delivery
Only the description of the set (1.5 m, red, blue, black, shielded) is mentioned. Batteries or other accessories are not included in the delivery scope.
