General
Plug diameter	4 mm
Insulation

This product from Chauvin Arnoux consists of a set of two measuring and test cables, specifically designed for the safe and precise execution of measurements in electrical engineering. The cables are each 3 metres long and consist of one red and one black cable, with the colours corresponding to electrical polarity: red for positive, black for negative. Each cable features a straight banana plug with a diameter of 4 mm at one end, and an angled banana plug with the same diameter at the other end. The plugs are insulated to ensure safe operation even at higher voltages. The cables are suitable for use in laboratory environments, during maintenance work, or during commissioning of electrical installations, where a reliable connection between measuring device and test object is required.

Measuring and test cables are indispensable in electrical engineering for checking voltages, currents, or resistances. These cables enable a safe and mechanically stable connection, with the angled shape at one end facilitating installation in confined spaces or on devices with limited space. The insulation of the banana plugs protects against unintended contact and reduces the risk of short circuits. The length of 3 metres provides sufficient freedom of movement without the cables becoming too long and thus unwieldy.

Functions and equipment in detail

The cables are designed as safety measuring leads, meaning they meet the requirements for electrical safety as specified in standards for measuring instruments and accessories. The use of insulated banana plugs with a diameter of 4 mm ensures a safe and reliable connection to measuring devices equipped with corresponding sockets. The cables are available in two colours (red and black) to clearly indicate polarity – an important measure to avoid incorrect connections. Each cable is 3 metres long, providing sufficient reach for many applications without the connection becoming too long and potentially unstable.

Technology explained simply

The banana plugs with a 4 mm diameter are a standard in measurement technology and fit most measuring devices equipped with sockets for this plug type. The insulation of the plugs protects against electrical contact and increases safety when working with voltages. The angled shape at one end allows for better placement in confined spaces, for example, on devices with protruding sockets or in enclosures. The length of 3 metres represents a compromise between handling convenience and reach, making the cables flexible to use without becoming too long and thus cluttered.

The cables are supplied as a set of two leads, with one cable featuring a straight plug and the other an angled plug. This combination allows flexible adaptation to different connection geometries. The colour coding (red/black) supports correct polarity assignment, which is particularly important when measuring direct voltage.

Compatibility and accessories

These measuring and test cables are compatible with measuring devices equipped with sockets for banana plugs with a diameter of 4 mm. This includes a wide range of multimeters, oscilloscopes, current and voltage sources, and other measuring instruments used in electrical engineering and electronics. The cables are not specifically designed for a particular manufacturer or model, but conform to a general industry standard, making them universally usable.

Installation and mounting

Installation is carried out by simply inserting the banana plugs into the corresponding sockets of the measuring device and the test object. The angled shape at one end facilitates connection in confined spaces or on devices with protruding terminals. The cables are flexible and can be easily bent without damaging the insulation. It is recommended to avoid excessive bending or twisting to extend the service life. The cables are not designed for use in explosive environments, as no corresponding approvals are mentioned.

Advantages in operation

The cables provide a safe and reliable connection suitable for daily work in electrical engineering. The insulation of the plugs increases safety, the colour coding simplifies polarity assignment, and the combination of straight and angled plugs offers flexibility during installation. The length of 3 metres provides sufficient freedom of movement without the cables becoming too long and thus unwieldy. The cables are designed for use in laboratory and maintenance environments, where a stable and safe measurement connection is required.
