The Chauvin Arnoux CA 6131 is a multifunctional installation tester designed for verifying the electrical safety of electrical installations. It meets the requirements of standards DIN VDE 0100-600 and DIN VDE 0105-100 and is suitable for testing new installations, maintenance work, and fault diagnosis. The device is compact, lightweight, and designed for mobile use, with operation simplified by a clear, unambiguous assignment of functions to controls.

Applications

The CA 6131 is used in electrical installation technology to ensure the safety of electrical systems. This includes testing new installations before commissioning, maintenance and inspection work on existing systems, and fault localization. The device is particularly suitable for testing services and electrical specialists who require quick and reliable assessment of installation safety.

Functions and Equipment in Detail

The device offers a wide range of measurement and testing functions. These include continuity testing, insulation testing, loop and network impedance measurement (Zs, Zi), and testing of residual current devices (RCDs/FI). Continuity testing is performed with a test current of at least 200 mA, with line resistance compensation up to 5 Ω. Insulation testing can be carried out with test voltages of 250 V and 500 V, with a measurement range up to 999 MΩ. Loop impedance measurement enables determination of Zs (Z L-PE) without and with tripping, with short-circuit current Ik calculated. RCD/FI testing supports types A and AC with calibrations from 30 mA to 650 mA and can be performed in pulse or ramp mode. Tripping time is measured at 0.5 x I DN, 1 x I DN, and 5 x I DN, with measurements ranging from 5.0 to 300 ms. Tripping current measurement is performed in ramp mode at 30 mA. Additionally, the device indicates phase rotation direction, with measurements in the range of 45 to 550 V and 45 to 65 Hz.

Technology Explained Simply

The CA 6131 measures voltage up to 550 V AC and 800 V DC, with accuracy of ± (1 % L + 2 pt). Resistance measurement is performed in the range of 1 to 99.99 kΩ. Continuity testing is carried out with a test current of at least 200 mA, with accuracy of ± (2 % L + 2 pt). Earth fault voltage measurement is performed in the range of 1.0 to 25.0 V and 25.0 to 70.0 V with a resolution of 0.1 V and accuracy of ± (15 % L + 3 pt) and ± (5 % L + 2 pt) respectively. Current measurement is optionally possible via an external current clamp. The device is equipped with an LCD display with 231 segments and blue backlighting, ensuring readability even in poor lighting conditions. Power supply is via 6 AA batteries (LR6), with autonomy exceeding 1900 continuity measurements at 1 Ω.

Compatibility and Accessories

The device is compatible with various accessories that extend its functionality. These include an earthing measurement accessory set with two earth electrodes (50 m), a continuity testing probe, a current clamp MN73 CV 2-200/2, crocodile clips CAT IV-1000 V 15 A red + black, test probes with 4 mm socket CAT IV and CAT III 1000 V PVC red and black, and test leads with 4 mm straight/angled plugs, 1.5 m, 15 A, CAT IV, 1000 V, PVC, red + black. These accessories enable flexible and safe application in various testing scenarios.

Mounting and Installation

The device is designed for mobile use and requires no mounting. It features a foldable support stand allowing placement on a table. A 4-point carrying strap enables hands-free operation. Connections are precisely labeled (L, N, PE, +, com) to prevent connection errors. An external probe allows remote operation during tests. A 3-pole test lead enables direct measurements at Type E sockets.

Operational Advantages

The CA 6131 offers high user-friendliness and efficiency. Clear operation, display backlighting, and precise labeling of connections reduce errors and speed up workflow. Integrated calculation of short-circuit current Ik and immediate display of test results (OK/not OK) increase test reliability. The device is designed for use in environments from 0 to 40 °C and meets protection class IP 54 (IEC 60529) and IK 04 (IEC 50102), making it suitable for indoor use. Compliance with IEC 61557 parts 1, 2, 3, 4, 6, 7, and 10, as well as EMC standards IEC 61326-1, IEC 61010-1, IEC 61010-2-030, and IEC 61010-2-034, ensures safety and reliability. Installation voltage is in the range of 90 to 450 V at a frequency of 45 to 65 Hz. The device is suitable for use in 600 V CAT III networks, with charging input at 300 V CAT II.

Protection and Environment

The device is designed for use in environments from 0 to 40 °C and can withstand storage temperatures from -10 to 70 °C (relative humidity 80 %). Protection class IP 54 protects against dust and splashing water, making it suitable for indoor use. IK 04 protection class protects against mechanical impacts. Power supply is via 6 AA batteries (LR6), with autonomy exceeding 1900 continuity measurements at 1 Ω. Dimensions are 223 x 126 x 70 mm, weight is approximately 1.1 kg.

Ergonomics and Operation

Operation of the CA 6131 is simple and intuitive. The foldable support stand allows placement on a table, while the 4-point carrying strap enables hands-free operation. The display with backlighting ensures good readability even in poor lighting conditions. Precise labeling of connections (L, N, PE, +, com) prevents connection errors. An external probe allows remote operation during tests. The 3-pole test lead enables direct measurements at Type E sockets. Test results (OK/not OK) are displayed immediately, increasing testing efficiency.
