Voltage detection without contact

The compact pocket multimeter CA 703 from Chauvin Arnoux is a portable measuring instrument for mobile use in electrical contracting and maintenance technology. It features a compact design and permanently connected test leads, ensuring immediate readiness for use. The device is designed for measuring direct and alternating voltages, currents, and resistances, and also offers functions such as continuity testing, diode testing, and non-contact voltage detection. The integrated flashlight supports work in poorly lit or hard-to-reach areas. The display has a resolution of 2000 points, enabling precise representation of measurement values. The range selection is automatic (AUTORANGE), simplifying operation.

Applications
This multimeter is suitable for daily use in electrical engineering, particularly for measurements in low-voltage installations. It is frequently used for maintenance, repair, and testing of electrical installations. The non-contact voltage detection allows for quick and safe identification of energized conductors without direct contact. The continuity test with an audible signal (beeper) helps check connections and circuits for electrical continuity. The diode test enables testing of semiconductor components, with the test signal having a voltage of up to 1.999 V and a current of up to 1 mA.

Functions and Equipment in Detail
The device measures direct voltage in the range of 200.0 mV to 600 V and alternating voltage from 2.000 V to 600 V. The accuracy for direct voltage is ± 0.5 % of the measured value plus 3 digits for the range 200 mV to 600 V; for higher values, the accuracy is ± 1.2 % L + 3 D. For alternating voltage (0–400 Hz), the accuracy is ± 1.0 % L + 8 D for 2.000 V and 20.00 V, and ± 2.3 % L + 10 D for 200.0 V and 600 V. Current measurement covers direct and alternating current from 200.0 µA to 200.0 mA, with accuracy of ± 2.0 % L + 8 D at 200.0 µA and 2000 µA. Resistance measurement ranges from 200.0 Ω to 20.00 MΩ, with accuracy varying by range from ± 0.8 % L + 5 D (200.0 Ω) to ± 10.0 % L + 5 D (20.00 MΩ). The maximum test voltage for resistance measurements is 600 Vrms.

Technology Explained Simply
The integrated flashlight facilitates work in dark or poorly lit areas, such as in enclosures or cable ducts. Non-contact voltage detection allows checking whether conductors are energized without direct contact. The electronic protection in the current measurement range protects the device against overloads up to 500 V. Automatic range selection (AUTORANGE) automatically selects the appropriate measurement range, speeding up operation and reducing error sources. The 2000-point display enables high resolution and precise value indication.

Compatibility and Accessories
The multimeter is designed for use in electrical installations according to IEC 61010 standards, with an installation category of 600 V CAT IV and 1000 V CAT III. This makes it suitable for use in distribution networks and at consumer switches. As an accessory, a transport case is available, which can safely transport and protect the device.

Mounting and Installation
The device is designed as a handheld measuring instrument and requires no mounting. The permanently connected test leads are directly attached to the device, enabling immediate use. Operation is performed via buttons on the device, which activate the various measurement functions.

Operational Advantages
The CA 703 is characterized by its compactness, high functionality, and user-friendliness. The combination of fixed test leads, automatic range selection, and integrated flashlight makes it particularly suitable for mobile applications. The safety standards IEC 61010 CAT IV/600 V and CAT III/1000 V ensure safe use in various electrical environments. The wide range of measurement functions in a compact device increases work efficiency.

Standards and Safety
The device complies with IEC 61010 and is approved for use in electrical installations with an installation category of 600 V CAT IV and 1000 V CAT III. These categories refer to the maximum permissible voltage and safety requirements for measuring instruments in different environments, with CAT IV representing the highest requirements for insulation and protection. The electronic protection in the current measurement range protects the device and user against overloads up to 500 V.
