Chauvin Arnoux P01120761 F65 multi-function clamp / leakage current clamp (RMS) content_copy

The Chauvin Arnoux F65 is a TRMS AC multi-function clamp meter, specifically designed for the precise detection and measurement of leakage currents in electrical installations. The device is used for diagnosing insulation faults and unintended tripping of RCDs, while also providing all basic functions of a multimeter clamp. The clamp features a TRMS converter, which delivers accurate readings even with distorted signals, making it essential for the precise analysis of complex electrical systems. The high sensitivity of 10 µA and interference suppression of 70 dB enable precise measurement even at low currents and in noisy environments.

Applications

The F65 is primarily designed for electrical maintenance and fault diagnosis in live installations. It is particularly suitable for testing installations where leakage currents occur due to insulation faults or faulty RCDs. The clamp is used in electrical installation, building maintenance, and industrial electrical engineering, where reliable current measurement and fault localization are required.

Functions and Equipment in Detail

The clamp offers a wide range of measurement functions: AC and DC voltage up to 600 V, AC current measurement from 30 µA to 100 A, resistance measurement from 0.1 Ω to 1 kΩ, and an audible continuity test below 35 Ω. Additional functions include maximum value storage (MAX), relative measurement, display HOLD, and PEAK display. These functions facilitate the analysis of measurement results and documentation of values during testing.

Technology Explained Simply

TRMS technology (True Root Mean Square) ensures that measurements are correctly displayed even with non-sinusoidal signals, such as those occurring with electronic loads or non-linear consumers. The integrated harmonic filter (50/60 Hz, switchable) reduces interference from network harmonics and supports fault finding in complex electrical systems. The 10,000-point display with backlighting ensures clear readability even in poorly lit environments. Automatic power-off and battery status indication ensure efficient use and extend battery life.

Compatibility and Accessories

The F65 features a jaw opening diameter of 28 mm, enabling measurement on cables and conductors with corresponding diameters. Suitable accessories include various test leads with 4 mm plugs (straight and angled), test probes, crocodile clips, and special adapters for Schuko sockets. These components expand the clamp’s application range and allow flexible adaptation to different measurement tasks.

Mounting and Installation

The clamp is closed directly around the conductor to be measured, with the jaw clamping the conductor. Measurement is contactless, enabling safe and quick testing. Operation is via buttons on the device, controlling various measurement functions and settings. The clamp is compact and designed for use in electrical installation.

Advantages in Operation

The combination of high sensitivity, interference suppression, and TRMS technology makes the F65 a reliable tool for electrical fault diagnosis. Integrated functions such as HOLD, MAX, and relative measurement support field work. The safety category 300 V CAT III ensures use in electrical installations up to 300 V, providing the required protection for the operator. The device is supplied with a storage pouch, batteries, and user manual, enabling immediate operation.
