The F203 multi-function clamp meter from Chauvin Arnoux is a professional measuring instrument for electricians and small to medium-sized enterprises in the electrical industry. It is designed for precise measurement of alternating and direct current, as well as other electrical quantities, in a wide range of applications. The device is based on a TRMS system, which delivers accurate readings even with irregular signal waveforms, and features automatic range selection as well as automatic detection of AC and DC voltages. The clamp meter is designed for use in electrical installations with a safety category of CAT IV 600 V, making it suitable for professional use in electrical engineering.

Applications

The F203 is suitable for a variety of tasks in electrical contracting, particularly for testing and maintenance of electrical installations, diagnosing circuits, and measuring inrush currents. The True InRush function enables easy determination of inrush currents for motors or other loads, which is helpful during commissioning or troubleshooting. The integrated temperature measurement with Type K thermocouples allows monitoring of temperatures in electrical devices or installations. The adapter function enables direct connection of external sensors, such as luxmeters or tachometers, to display their readings directly on the clamp’s display.

Functions and Equipment in Detail

The clamp offers a wide range of measurement functions: current measurement up to 600 A AC and 900 A DC, voltage measurement up to 1000 V AC/DC, resistance measurement up to 60 kΩ, audible continuity testing with adjustable threshold between 1 Ω and 599 Ω, diode test, and temperature measurement in the range of -60.0 °C to +1000 °C (or -76 °F to +1832 °F). Automatic range selection (Autorange) and automatic AC/DC detection simplify operation, as no manual settings are required. Additional functions include HOLD, MIN/MAX, relative measurement (ΔX/X), and the adapter function for external sensors.

Technology Explained Simply

The TRMS system (True Root Mean Square) ensures that readings are accurate regardless of signal waveform — even with distorted or non-sinusoidal currents. This is particularly important for modern electronic loads, which often generate non-sinusoidal currents. The safety category CAT IV 600 V means the device is approved for measurements near power distribution equipment, such as distribution boards or main meter cabinets. Accuracy is 1 % of the measured value plus 3 digits, which is sufficient for professional applications. The jaw opening diameter of 34 mm allows measurement of conductors up to this diameter.

Compatibility and Accessories

The F203 can be expanded with various accessories to broaden its application range. These include adapters for Type K temperature sensors, test leads with 4 mm connectors (straight and angled), alligator clips, test probes, and various thermocouples such as SK11, SK13, SK14, SK15, SK17, SK19, and SK6. These sensors enable temperature measurement on different surfaces or in airflows. Additionally, test leads with PVC or silicone insulation, CAT IV 1000 V, are available. A multi-purpose magnetic holder Multifix and a carrying case (120 x 245 x 60 mm) support practical use.

Installation and Mounting

The clamp meter is placed directly around the conductor to be measured. The jaw opens by pressing a button, allowing the conductor to be inserted. Measurement is performed without direct contact with the conductor, enabling safe and quick testing. The test leads are included in the delivery and can be connected to the appropriate terminals on the clamp. Operation is via buttons on the device, which activate the various measurement functions.

Operational Advantages

The F203 offers high measurement accuracy, broad functional versatility, and a robust design. Automatic functions such as Autorange and AC/DC detection reduce the risk of errors. The True InRush function and adapter function significantly expand application possibilities. The high safety category CAT IV 600 V makes the device suitable for use in electrical installations. The integrated temperature measurement enables monitoring of heat development in electrical components, which is helpful for troubleshooting. The included test leads and carrying case facilitate transport and storage.

Scope of Delivery

The scope of delivery includes the F203 multi-function clamp meter, test leads, a carrying case, the user manual, and batteries.
