This accessory set from Chauvin Arnoux consists of two probes with insertion needles in the colours red and black, and is specifically designed for use in electrical installations of category CAT II and lower. The probes are used for precise testing and measurement on cables, where the insertion needles enable safe and damage-free penetration of the cable insulation. The maximum operating voltage is 30 V AC or 60 V DC, ensuring safe and reliable use in low-voltage installations. The probes are suitable for low-voltage applications and are used in laboratories as well as for general electrical testing.

Applications
This accessory is intended for installations in safety category CAT II and lower, which is typical for measurements on consumer voltage installations such as in buildings, laboratory environments, or during maintenance work on electrical devices. The limited voltage level of 30 V AC or 60 V DC protects the user and the measuring device from excessive risks during uncontrolled or erroneous measurement procedures. Therefore, the probes are not suitable for high-voltage installations or industrial applications with higher voltages.

Functions and Equipment in Detail
The probes feature sharp, precise insertion needles that allow penetration of cable insulation without damaging the underlying conductor material. The colour coding in red and black supports clear identification of polarity during measurements, especially for distinguishing between positive and negative poles in DC installations or phase differentiation in AC installations. The needles are designed to ensure a secure and reproducible electrical contact.

Technology Explained Simply
The insertion needles are specifically designed for use at low voltages. The maximum voltage of 30 V AC or 60 V DC corresponds to the voltage range commonly found in many household and laboratory applications. The safety category CAT II refers to measurements on consumer voltage installations that are not directly connected to the main supply, but are supplied via an intermediate stage such as a transformer or socket. Therefore, the probes are designed for use in controlled environments where the risk of overvoltage or short circuits is limited.

Compatibility and Accessories
The accessory is intended as a supplement for measuring and test instruments used in low-voltage installations. It is specifically designed for installations in category CAT II and lower, making it compatible with measuring instruments approved for this application area. The probes can be connected to suitable measuring instruments to measure voltage on cables without damaging them. Use is in conjunction with a measuring instrument that supports the corresponding voltage class.

Installation and Mounting
The probes are inserted directly into the insulation of a cable to establish an electrical contact with the conductor. The needles are designed to penetrate the insulation without damaging the cable. Installation requires no tools and is quick to perform. The colour coding facilitates polarity identification. User instructions included in the delivery provide additional guidance for safe handling.

Operational Advantages
The probes enable quick and safe measurement on cables without damaging the cable. The colour coding supports correct polarity assignment, reducing measurement errors. The limitation to 30 V AC or 60 V DC ensures high safety during handling, especially in environments where no high voltage is present. Use in laboratories or during maintenance work on electrical devices is particularly advantageous, as measurements can be performed precisely and without additional preparation.

The delivery includes two probes with insertion needles in the colours red and black, as well as user instructions. The probes are designed for use in low-voltage installations and are not suitable for higher voltage ranges. The safety category CAT II is crucial for correct application and compliance with safety regulations during measurements.
