These removable test probes from Chauvin Arnoux are specifically designed for the voltage testers C.A 745N, C.A 755, and C.A 757. They serve as replacement or exchange probes for measurements in the field of electrical engineering, particularly in residential installations and low-voltage applications. The probes feature a diameter of 4 mm and are designed for safety category CAT II, making them suitable for applications with low risk of electric shock. They are used together with the corresponding test leads to ensure safe and precise contact.

Applications
These test probes are intended for measurements on devices connected to earthed sockets, as well as for work on low voltages in electronics and telecommunications. They are also suitable for testing installations or devices that are disconnected from the power source of the distribution network. The applications include residential environments and areas where the voltage is below 300 V, which corresponds to the maximum voltage class of the CAT II category.

Functions and Features in Detail
The probes are designed to be removable, enabling easy maintenance and replacement. The 4 mm diameter provides sufficient contact surface to ensure stable and reliable measurements. The probes are available in red and black, allowing for clear distinction between positive and negative poles. Compatibility with the specified voltage testers is ensured by the specific plug connection.

Technology Explained Simply
The safety category CAT II refers to measuring instruments used in electrical installations with lower risk, such as household appliances or socket outlets. Therefore, the test probes are designed for applications where the voltage does not exceed 300 V. The 4 mm probe ensures sufficient contact surface to avoid measurement errors caused by poor connection. The removable design allows for easy cleaning or replacement in case of wear.

Compatibility and Accessories
The test probes are exclusively designed for the voltage testers C.A 745N, C.A 755, and C.A 757 from Chauvin Arnoux. They are not suitable for other measuring instruments or voltage classes. The probes are part of a set consisting of two units, one red and one black.

Installation and Mounting
Mounting is done by simply inserting the test probe into the corresponding socket connector of the voltage tester. No additional tools or mounting procedures are required. The connection is mechanically stable and ensures secure electrical contact. The instruction manual for safe use is included in the delivery and provides guidance on proper handling.

Operational Advantages
The removable design allows for easy maintenance and replacement in case of wear. The clear color coding (red/black) supports correct polarity assignment. The 4 mm probe ensures reliable contact, increasing measurement accuracy. The CAT II approval ensures safe use in the intended application areas and protects the user from excessive risks.
