General
Output/input ratio	100 mV DC / A AC

The MINI 09 current clamp from Chauvin Arnoux is a compact current clamp for measuring alternating currents in tertiary or industrial applications with low power. It serves as accessory for multimeters and enables precise capture of current values, especially when the connected measuring device has insufficient alternating current sensitivity. The DC output of the clamp overcomes this limitation by providing an analog signal in the form of direct voltage, which can be easily measured by a multimeter.

Applications
The MINI 09 is designed for use in service and industrial applications where small to medium current strengths need to be measured. Due to its compact design with a clamping diameter of 10 mm, it is particularly suitable for tight spaces, for example when testing sockets, small cables, or in enclosures. The current clamp is rated for nominal currents up to 150 A AC, making it suitable for a wide range of applications in electrical trades and maintenance technology.

Functions and Equipment in Detail
The clamp generates an output signal in the form of direct voltage, with the output-to-input ratio being 100 mV DC per ampere AC. This linear relationship allows for simple and accurate conversion of the measured voltage value into the actual current value. The output is delivered via an attached cable with insulated 4-mm connectors, ensuring a secure and vibration-resistant connection to the measuring device. The connectors are designed for use with standard multimeter terminals.

Technology Explained Simply
The current clamp operates on the principle of inductive current measurement: when a current-carrying conductor is passed through the clamp's opening, a magnetic field is generated, which induces a voltage in the clamp. This induced voltage is converted into a direct voltage signal, which is transmitted to the measuring device via the cable. The conversion to direct voltage is crucial to enable measurement on devices that lack sufficient alternating current sensitivity. The protection rating of the clamp is specified as 600 V CAT III / 300 V CAT IV, allowing its use in electrical installations with the corresponding voltage category and ensuring high safety during measurement.

Compatibility and Accessories
The MINI 09 is designed as accessory for multimeters and can be connected to devices equipped with 4-mm terminals. The current clamp is part of the MINI series from Chauvin Arnoux, which also includes other models such as the MINI 05, also intended for use with multimeters. Use is exclusively in conjunction with an external measuring device; the clamp does not feature an integrated display or digital output.

Mounting and Installation
Installation is performed by simply clamping the conductor to be measured. The clamp opening has a diameter of 10 mm, meaning only thin conductors or individual wires can be measured. Connection to the measuring device is made via the included cable with insulated 4-mm connectors. No additional tools or mounting procedures are required.

Advantages in Operation
The MINI 09 is characterised by its compactness and ease of use. The direct voltage output enables precise measurement even on devices with low alternating current sensitivity. The insulated connectors ensure a secure connection, and the protection category CAT III/IV guarantees safe use in electrical installations. The clamp is thus a reliable tool for electrical specialists who value precise and safe current measurement in limited space.
