General
Plug diameter	4 mm

Test leads with test probes from Chauvin Arnoux serve as accessories for measuring instruments in the field of electrical engineering. They consist of PVC-insulated cables and are equipped with insulated angled connectors with a diameter of 4 mm. The leads are available in a length of 1.5 m and enable a safe and precise connection between measuring instrument and measurement object. The colour coding is red and black, which facilitates differentiation between positive and negative poles during measurement. These leads are designed as replacement or supplementary accessories for a wide range of measuring instruments used in industrial and craft applications.

Applications
These test leads are intended for use in electrical installations and equipment where safe and reliable measurement of voltage, current, or resistance is required. Due to the safety category CAT IV/1000 V and CAT III/600 V, they are suitable for measurements in main distribution boards, distribution boxes, and other primary circuits. The cables are designed for use in electrical installations with an operating voltage up to 1000 V in CAT IV areas and up to 600 V in CAT III areas. This includes, for example, measurements at meter connections, main switches, or in industrial distributions.

Functions and Equipment in Detail
The leads feature test probes that enable precise and safe contact with measurement points. The angled connectors with a diameter of 4 mm are insulated, preventing accidental contact with conductive parts and thus increasing the operator’s safety. The maximum current rating is 15 A, which is sufficient for use in electrical installations and device testing. The PVC insulation provides good protection against mechanical damage and offers adequate electrical insulation.

Technology Explained Simply
The designation CAT IV/1000 V refers to the safety category and the maximum voltage at which the leads can be safely used. CAT IV describes the highest safety level for measurements in primary distribution, for example at meter connections or main lines. The 1000 V rating means the leads are suitable for measurements at voltages up to 1000 V in CAT IV areas. In CAT III areas, such as in distribution boards or on equipment, they are approved for voltages up to 600 V. The PVC insulation ensures high electrical resistance and protects against short circuits. The length of 1.5 m provides sufficient freedom of movement during work, without the leads being excessively long and thus unwieldy.

Compatibility and Accessories
The test leads are designed as standard accessories for many measuring instruments from Chauvin Arnoux and other manufacturers. They fit devices equipped with 4-mm angled connectors and can be used as replacement or supplementary parts. The cables are supplied as a set of two leads (red and black), supporting standardisation in measurement operations.

Installation and Mounting
Installation is done by simply inserting the angled connectors into the corresponding sockets of the measuring instrument. The test probes are connected directly to the measurement points. The leads are flexible and easy to handle. No additional tools or mounting aids are required. The connection is mechanically stable and provides secure electrical contact.

Operational Advantages
The combination of PVC insulation, insulated angled connectors, and test probes ensures high safety during measurement. The colour coding simplifies polarity assignment. The length of 1.5 m provides sufficient freedom of movement without the leads being excessively long. The maximum current rating of 15 A is sufficient for most applications in electrical installations. The cables are robust and suitable for use in industrial and craft environments.
