General
Maximum voltage	300 V
Tip diameter	4 mm

Removable test probes from Chauvin Arnoux, specifically designed for use in low-voltage applications and residential environments. These test probes are designed for test leads with a 4 mm plug diameter and feature a fully sheathed, insulated tip with a diameter of 4 mm. The socket also has a diameter of 4 mm, enabling a secure and standardized connection with compatible measuring instruments. The test probes are designed for Category CAT II and below, making them suitable for applications with low electrical risk, such as devices connected to earthed sockets or work involving low voltages in electronics and telecommunications. The maximum voltage is 300 V, covering use in domestic and similar environments where voltage does not exceed 300 V.

Applications
These test probes are intended for applications where electrical voltage is below 300 V and the risk of electric shock is low. This includes measurements on devices powered via earthed sockets, as well as work in electronics, telecommunications, or installations using energy sources separate from the public power grid. Category CAT II ensures sufficient safety for these scenarios, which typically occur in residential and small-scale installations.

Features and Equipment in Detail
The test probes are fully sheathed and insulated, enabling safe handling. The tip has a diameter of 4 mm and is designed for precise and secure contact. The 4 mm socket ensures compatibility with standard test leads. The color coding (red and black) supports differentiation between positive and negative poles, which is helpful when performing measurements. The test probes are removable, allowing them to be easily attached to various test leads.

Technical Explanation
Category CAT II refers to the safety class for measuring instruments and accessories suitable for applications near consumers and in domestic environments. The maximum voltage of 300 V is sufficient for most domestic applications, as voltage in residential buildings is typically 230 V. The full sheathing of the tip ensures the user does not come into direct contact with conductive parts, minimizing the risk of electric shock. The 4 mm plug connection is a standard in measurement technology and ensures a secure and stable connection.

Compatibility and Accessories
The test probes are designed for test leads with a plug diameter of 4 mm. They are therefore compatible with a wide range of measuring instruments and leads that support this standard. The color coding (red and black) enables clear assignment to positive and negative poles, which is helpful when performing measurements.

Installation and Mounting
The test probes are removable and can be easily connected to suitable test leads with a 4 mm plug diameter. Installation is done by simply inserting them into the socket of the lead. No additional tools or mounting procedures are required. The test probes are ready for immediate use after being attached to the lead.

Operational Advantages
The full sheathing of the tip increases safety during handling, especially in environments with low electrical risk. The 4 mm plug connection ensures universal compatibility with many test leads. The color coding simplifies polarity assignment, reducing error rates during measurements. The removability allows flexible use with different leads and devices.

Scope of Delivery
The scope of delivery includes two test probes, one red and one black. The test probes are ready for immediate use after being attached to suitable test leads.
