Dimensions / weight	160 x 105 x 56 mm / 500 g

The Chauvin Arnoux CA 5003 is an analogue multimeter with a compact, shock-protected housing designed for use in electrical contracting. It features a foldable stand bracket enabling stable placement, and is designed for measuring direct voltage, alternating voltage, direct current, alternating current, resistance, as well as for acoustic continuity testing. The device is suitable for installations up to safety category CAT III 600 V according to IEC 61010-1 Edition 2, and offers a robust, compact design with dimensions of 160 x 105 x 56 mm and a weight of 500 g.

Applications
This multimeter is intended for use in electrical installations within the low-voltage technology sector, particularly in installations complying with the IEC 61010-1 Edition 2 standard. It is suitable for electrical testing, maintenance work, and fault diagnosis in buildings, industrial facilities, and during the commissioning of electrical installations. The IP53 protection rating ensures protection against dust and splashing water, making it suitable for indoor use and slightly damp environments. The operating temperature ranges from −10 °C to +55 °C at a relative humidity below 90 %.

Functions and Equipment in Detail
For alternating voltage, 5 ranges from 10 V to 1000 V are available. Current measurement includes 7 ranges for direct current from 50 µA to 15 A and 5 ranges for alternating current from 1.5 mA to 15 A. Resistance measurement is available in two ranges: 10 kΩ and 1 MΩ. Typical accuracy is 1.5 % for direct voltage, 2.5 % for alternating voltage and alternating current, and 10 % for resistance measurements. An integrated acoustic continuity test signals resistances below 50 Ω. A dB scale for alternating voltage (0 to +22 dB) enables voltage level measurement in logarithmic representation.

Technology Explained Simply
The multimeter operates with an analogue pointer display system, providing continuous visual representation of measured values. The internal resistance is 20 kΩ per volt, ensuring minimal loading of the measurement point. The operating frequency ranges from 10 Hz to 100 kHz, depending on the selected measurement range. Power supply is via a 9-V battery (type 6LR61), enabling 10,000 measurements of 10 seconds each. The device is equipped with high-performance fuses (1.6 A and 16 A) providing electronic protection. An illuminated indicator “Fus” signals the status of the fuses for current measurement ranges. The “Voltest” function lights up when an external voltage is present during resistance measurement or continuity testing, providing additional safety. An automatic zero adjustment in the ohmmeter function ensures precise zero setting without manual adjustment.

Compatibility and Accessories
The multimeter can be combined with various test leads and accessories suitable for use in electrical installations. These include test leads with 4 mm connectors (straight and angled), test probes (CAT III and CAT IV, 1000 V), current clamps (e.g. MN11 LCA 200/0.2, MN89 CV 200/20DC), and pickup tongs (alligator clips, needle probes). Transport cases and transport bags are also available as accessories. The test leads are rated for 15 A and 1000 V and are made of silicone or PVC. The use of CAT IV or CAT III accessories is recommended to meet safety requirements.

Mounting and Installation
The device is handheld and connected directly to measurement points. No mounting or installation is required. The test leads are connected to the corresponding sockets on the multimeter, with colour coding (red/black) indicating polarity. Readings are displayed via the analogue pointer, which is read against a scale. Operation is performed using a rotary knob to select measurement functions and ranges.

Operational Advantages
The CA 5003 offers a combination of low cost, high functionality, and sufficient safety for daily use in electrical contracting. The analogue display allows for quick visual assessment of measured values, especially during dynamic changes. Integrated safety features such as the “Voltest” indicator and fuse status indicator enhance operational safety. The robust construction and foldable stand bracket facilitate use in various working environments. The long autonomy provided by a single 9-V battery reduces the need for frequent battery replacements.
