The Chauvin Arnoux CA 6133 is a multifunctional test instrument for verifying the electrical safety of installations in accordance with standards such as DIN VDE 0100-600 and DIN VDE 0105-100. It is used for testing new installations before commissioning, maintaining existing installations, and locating faults. The device combines various measurement functions in a compact, user-friendly design and is designed for field use.

Applications

The CA 6133 is used for testing electrical installations in residential and commercial buildings, for maintenance and servicing, and for verifying safety functions. It enables the performance of continuity tests, insulation measurements, loop and network impedance measurements (Zs, Zi), FI/RCD tests, and the measurement of voltage, frequency, and current via an external clamp. The functions are designed for testing Type A and AC residual current devices and support compliance with IEC 61557 conformity in parts 1 to 7 and 10.

Functions and Equipment in Detail

The device features an automatic test sequence that successively tests the loop, RCD, and insulation, thereby reducing time and effort. Results are displayed directly as pass or fail. The FI/RCD test includes testing in pulse mode (trip time) and ramp mode (trip current) for residual current devices with rated trip currents of 30 mA, 100 mA, 300 mA, 500 mA, and 650 mA. Earth resistance measurement is performed using an auxiliary earth electrode, with earth resistance measurable up to 2000 Ω. Loop impedance measurement allows determination of Zs (Z L-PE) without tripping up to 2000 Ω and with tripping, as well as Zi (Z L-N or Z L-L) in the range 0.1 to 400 Ω. The short-circuit current Ik is calculated in the range 1 to 9.999 A.

Technology Explained Simply

Measurements are performed at a frequency of 128 Hz, ensuring precise impedance measurement. The compensation function for test leads up to 5 Ω reduces measurement errors caused by lead resistance. Voltage measurement covers a range of 2.0 to 550.0 V AC and 0.0 to 800.0 V DC with a resolution of 0.1 V. Frequency measurement is performed in the range 30.0 to 999.9 Hz with a resolution of 0.1 Hz. The rotating field direction indicator is available in the range 45 to 550 V and 45 to 65 Hz. Measurement accuracy is ±(1 % L + 2 pt) for voltage and ±(0.1 % L + 1 pt) for frequency at voltages > 2 V. Insulation measurement is performed at test voltages of 250 V, 500 V, and 1000 V, with accuracy varying between ±(2 % L + 5 pt) and ±(2 % L + 10 pt) depending on the range. Continuity testing is performed with a test current of at least 200 mA, measuring in the range 0.00 to 9.99 Ω with a resolution of 0.01 Ω.

Compatibility and Accessories

The device is equipped with a Bluetooth interface that enables connection to the Android application IT-Report. Via this app, test results can be transferred, test reports created, and sent. Power supply is provided by six rechargeable NiMH batteries, which can be charged via mains, USB, or cigarette lighter. Autonomy exceeds 1,700 continuity measurements at a resistance of 1 Ω. Optionally, an external current clamp MN73A can be used, which is automatically recognized. Suitable accessories include, among others, a set of 4 NiMH batteries, an earthing measurement kit with 2 earth electrodes (50 m), crocodile clips CAT IV-1000 V, test probes with 4 mm socket, a continuity test rod, test leads with 4 mm plug, and the current clamp MN73A.

Mounting and Installation

The device is ergonomically designed and allows for easy handling. It features a foldable support for tabletop use, a magnetic housing for attachment to metallic surfaces, and a 4-point carrying strap for hands-free operation. Connections are clearly labeled (L, N, PE, H, S, E, +, com) to avoid connection errors. An external probe enables remote control during testing. The 3-pole test lead allows direct measurements at Type E sockets. The display is an LCD with 231 segments and blue backlighting, improving readability in poor lighting conditions.

Advantages in Operation

Automatic test sequences and an integrated memory for 30 locations with 99 tests each increase operational efficiency. The Bluetooth connection to the Android app IT-Report enables digital documentation and sending of test reports. Rechargeable batteries and flexible charging options (mains, USB, cigarette lighter) ensure high mobility. The IP 54 protection rating (IEC 60529) and IK 04 protection rating (IEC 50102) provide protection against dust and splashing water, as well as against mechanical impacts. Operating temperature ranges from 0 to 40 °C, storage temperature from -10 to 70 °C at a relative humidity of up to 80 %. Compliance with standards IEC 61326-1, IEC 61010-1, IEC 61010-2-030, IEC 61010-2-034, and categories 600 V CAT III and 300 V CAT II at the charging input ensures electrical safety.
