Chauvin Arnoux P01654821 CA 1821 1-channel thermometer for thermocouples content_copy

The C.A 6511 is an economical insulation and continuity tester from Chauvin Arnoux, specifically developed for electricians, installers, and maintenance technicians. The device is used to test electrical installations and equipment for insulation resistance and continuity, and can be employed in both stationary and mobile applications. It features an analog display with a logarithmic scale, enabling good readability of measurement values, and is suitable for testing installations in the building services sector and the tertiary sector.

Insulation measurement

The tester enables measurement of insulation resistance in the range of 0.1 to 1000 MΩ with a test voltage of 500 V DC. The measurement accuracy is ± 5 % of the displayed values. This function is crucial for safety testing of electrical installations, as it checks electrical insulation and thus minimizes the risk of short circuits or electric shock. The test voltage of 500 V is suitable for use in CAT III networks up to 600 V, allowing application in many industrial and commercial installations.

Continuity testing

Continuity testing is performed in the range of -10 Ω to +10 Ω with a test current of at least 200 mA. The function includes current reversal, enabling testing of wiring and connections even in complex circuits. The accuracy is ± 3 % of full scale. This function is used to check electrical continuity, for example in cables, switches, or connections, to ensure there are no breaks.

Voltage measurement

The device measures alternating voltages in the range of 0 to 600 V AC with a frequency of 45 to 400 Hz. The accuracy is 3 % of full scale. This function enables direct verification of voltage absence, which is an important step in the maintenance and servicing of electrical installations. Measurement is performed via two color-coded input terminals, used for all measurement functions.

Technology and safety

The device is powered by four 1.5 V LR06 batteries and features electrical safety according to IEC 61010 for 600 V CAT III. Dimensions are 167 x 106 x 55 mm, weight 500 g (without case). The analog display is easy to read and allows quick evaluation of measurement results. Safety features include automatic voltage absence testing via direct measurement, as well as an integrated battery autonomy test, ensuring sufficient power for valid measurements.

Compatibility and accessories

Various accessories are compatible with the device, including a probe for continuity testing, test leads with two 4 mm straight plugs (1.5 m, 15 A, CAT IV-600 V, PVC, red + black), a high-performance fuse 1.6 A (600 V / 6x32 mm), and a shock protection case. These components support safe and efficient use of the tester in various working environments.

Applications

The C.A 6511 is particularly suitable for testing electrical equipment such as tools, appliances, enclosures, and cable routes. It is used in maintenance, servicing, and installation to ensure compliance with national and European standards (such as NFC 15-100, IEC 364, VDE 0413, BS 7671). The combination of insulation and continuity testing in a single device reduces effort and increases efficiency when testing electrical installations.

Operational advantages

The compact design, simple operation, and integrated safety features make the C.A 6511 a reliable tool for daily use. The analog display allows for quick visual assessment, while automatic functions such as voltage absence testing and battery test enhance safety. The use of standard batteries (LR06) ensures easy and cost-effective maintenance of the device.
