Chauvin Arnoux P01196311F CA 5011 multimeter with transport case content_copy

The Chauvin Arnoux CA 5011 is an analog/digital multimeter with TRMS measurement function, designed for precise measurement of DC and AC voltages, currents, resistances, frequencies, as well as continuity testing and diode tests. The device combines a digital display with 4000 digits for high measurement accuracy and an analog scale for quick reading and trend recognition. It is particularly suitable for installations with non-linear loads, as it displays the true RMS value (TRMS) regardless of signal shape, even with distorted or non-sinusoidal voltages and currents.

Applications
This multimeter is used in electrical installations operating up to category CAT III 600 V according to IEC/EN 61010-1 Edition 2. It is suitable for use in industry, crafts, and electrical installations where high safety requirements and accurate measurement results are necessary. Electrical safety complies with IEC 61010-1 Edition 2 with 600 V CAT IV, representing a high protection class for measuring instruments in electrical installations.

Functions and Equipment in Detail
The device features automatic AC/DC detection, enabling measurement of DC and AC voltages and currents without manual selection. Voltage measurement covers five ranges from 400 mV to 600 V, with an input resistance of 10 MΩ, ensuring minimal loading of the measurement point. Current measurement covers six ranges from 400 µA to 10 A. Resistance measurement is available in six ranges from 400 Ω to 40 MΩ. The acoustic continuity test detects resistances below 400 Ω and signals this with an audible tone. Frequency measurement includes three ranges from 4 kHz to 400 kHz.

Technology Explained Simply
TRMS measurement (True Root Mean Square) ensures that the actual RMS value of a signal is captured, regardless of whether the signal is sinusoidal or distorted. This is particularly important in modern electrical installations with non-linear loads such as frequency converters or LED lighting. The digital display offers high resolution of 4000 digits, while the analog scale enables quick visual detection of trends. The backlight allows use even in poor lighting conditions. The maximum value function stores the highest measured value over a period of more than 500 ms, which is useful for short-term voltage spikes.

Compatibility and Accessories
The multimeter can be combined with various accessories to adapt measurements to different connection types. These include alligator clips (crocodile clips), puncture needles, test leads with 4 mm connectors (straight and angled), test probes, and transport case. The test leads are rated for CAT IV 1000 V and are made of silicone or PVC, depending on the model. The fuses in the device are HPC fuses rated at 1 A and 10 A, with their status monitored via an indicator light (Fus"). Another indicator light ("Voltest) signals the presence of stray voltages during resistance measurement or continuity testing.

Mounting and Installation
The device is compact and portable, with dimensions of 160 x 105 x 56 mm and a weight of 500 g. It features a shock-resistant housing and a foldable stand bracket that allows stable positioning on a surface. Operation is performed via a rotary knob for selecting measurement functions and buttons for additional functions such as Hold, Max, and null point galvanometer.

Operational Advantages
The combination of digital and analog display provides optimal readability: precise values via the digital display and quick trend recognition via the analog scale. TRMS measurement ensures reliable results even with complex signals. Automatic AC/DC detection reduces operating effort. The backlight and maximum value function increase efficiency during measurement. Safety features such as the Fus" and "Voltest indicators enhance operational safety. The device is powered by a 9 V 6LR61 battery and offers an autonomy of 300 hours. The IP 53 protection rating protects against dust and splashing water, making it suitable for indoor use. The operating temperature range is from -10 °C to +55 °C at a relative humidity below 90%.

Protection and Safety
The device complies with IEC 61010-1 Edition 2 with 600 V CAT IV, representing a high safety class for measuring instruments in electrical installations. The HPC fuses rated at 1 A and 10 A protect the device against overloads. Indicator lights for fuses and stray voltages enhance operational safety. The IP 53 protection rating ensures protection against dust and splashing water, making it suitable for indoor use.
