These test probes from Chauvin Arnoux are specifically designed for the voltage testers C.A 771 and C.A 773. They serve as replacement or additional probes for safe and precise voltage measurement in electrical installations. The probes have a diameter of 4 mm, enabling reliable contact with measurement points. The construction complies with the IEC 61243-3 standard, which applies to safety requirements for testing equipment in electrical installations. The maximum voltage rating for the test probes is 1000 V, making them suitable for use in industrial and commercial electrical installations. The connector at the probe has a diameter of 4 mm and is female, ensuring a stable connection to the testing device.

Applications
These test probes are intended for professional use in electrical engineering, particularly for voltage testing in electrical installations. They are suitable for applications in industry, building management, as well as maintenance and repair work. Compliance with IEC 61243-3 ensures that the probes meet the safety and reliability requirements applicable to measuring instruments in electrical installations.

Functions and Features in Detail
The probes have a diameter of 4 mm, enabling secure and precise contact with measurement points. The female socket with a 4 mm diameter ensures a firm connection to the testing device. The probes are rated for voltages up to 1000 V, allowing their use in installations with low voltage up to industrial applications. Compliance with IEC 61243-3 ensures adherence to safety standards for testing equipment.

Technical Explanation
The IEC 61243-3 standard sets safety requirements for testing equipment in electrical installations. The test probes comply with this standard, meaning they are suitable for use in electrical installations and meet the required insulation and safety specifications. The maximum voltage of 1000 V refers to the electrical load capacity of the probes; they must not be used at higher voltages. The 4 mm connector enables a secure and slip-resistant connection to the testing device.

Compatibility and Accessories
The test probes are specifically designed for the voltage testers C.A 771 and C.A 773. They are not intended for other devices unless those devices feature a compatible 4 mm connector. Use with other devices is not recommended, as it could compromise safety. The probes are available as a set of two pieces (one red, one black), which facilitates differentiation between phases and neutral conductors.

Installation and Mounting
The test probes are inserted directly into the 4 mm socket connector of the voltage tester C.A 771 or C.A 773. The connection is made by simply inserting the female socket into the male connector of the device. No additional tools or mounting procedures are required. The instruction manual for safe use is included in the delivery and provides guidance on correct handling.

Operational Advantages
The test probes offer safe and precise voltage measurement up to 1000 V. Compliance with IEC 61243-3 ensures reliability in operation. The 4 mm plug connection ensures a stable connection to the testing device, preventing measurement errors caused by loose contacts. The colour coding (red/black) facilitates identification of conductors during measurement.
