Chauvin Arnoux P01102153Z Test probes, red/black, Ø 2 mm, CAT II content_copy

Removable test probes for voltage testers of models C.A 745N, C.A 755 and C.A 757 from Chauvin Arnoux are specifically designed for use in low-voltage applications and in residential environments. These test probes enable precise measurements on electrical devices connected to earthed sockets, as well as on electronic and telecommunications equipment. The safety category CAT II ensures sufficient protection for applications where the risk of electric shock is low, such as when testing installations that are separated from the distribution network’s power source. The probes have a diameter of 2 mm, allowing for targeted and safe contact with connection points without causing unintended short circuits.

Applications
The test probes are suitable for work in the field of electrical installation, maintenance of household appliances, as well as in telecommunications and electronics. They are used to check voltages at sockets, device connections or internal contacts, especially when devices are operated from earthed sockets. The application takes place in environments where voltage does not exceed 300 V and devices are not directly connected to the distribution network.

Functions and equipment in detail
The removable test probes are fitted with a crystal cap that enables safe and visible contact engagement. The 2 mm diameter ensures precise positioning on narrow contacts, which is advantageous when testing small electronic components or plug connections. The probes are designed for use with the specified voltage testers and can be connected to the corresponding test leads. The safety category CAT II is intended for installations in residential environments and for devices with low risk potential.

Technology explained simply
The test probes are designed as replacement or additional components for voltage testers that feature a 4-mm plug for test leads. The crystal cap serves as a visual confirmation of contact – it lights up as soon as voltage is detected. The safety category CAT II refers to the maximum voltage that can occur in the application and protects against dangerous overvoltages in the context of household appliances and low-voltage installations. The 2 mm diameter probe is designed for precise measurements to avoid unintended contact with adjacent conductors.

Compatibility and accessories
The test probes are specifically developed for the voltage testers C.A 745N, C.A 755 and C.A 757 from Chauvin Arnoux. They are compatible with the corresponding test leads designed for these devices. The probes are available as a set of two pieces (red/black), which facilitates differentiation between live and neutral conductors.

Mounting and installation
The test probes are connected to test leads equipped with a 4-mm plug. Installation is done by simply inserting them into the plug of the lead. The instruction manual for safe use is included in the delivery and provides guidance on correct handling and compliance with safety regulations.

Advantages in operation
The removable test probes allow for replacement of the test tips in case of wear or damage without having to replace the entire measuring device. The 2 mm probe enables precise and safe measurement on narrow contacts, which is particularly beneficial when servicing small electronic devices. The safety category CAT II ensures sufficient protection for the intended use in residential environments and low-voltage installations. The crystal cap provides visual feedback when voltage is detected, increasing workplace safety.

The delivery includes the removable test probes Ø 2 mm for models C.A 745N, C.A 755 and C.A 757, as well as an instruction manual for safe use.
