  • Description

    Chauvin Arnoux CA771 Voltage Absence Tester

    The Chauvin Arnoux CA771 Voltage Absence Tester is an excellent, safety-critical device that goes above and beyond the minimum standards required by European law. It can be used for testing for voltage and RCD testing in addition to extended continuity and resistance testing. A buzzer will sound should resistance fail to reach set limits (2kΩ, 6kΩ, 300kΩ). Other functions include single pole phase testing and two-wire phase rotation whilst the redundant hazardous voltage indication (Extra-Low Voltage) safety feature allows the user to see the presence of voltage via a flashing LED. Furthermore, stray voltage function (low impedance mode) can be switched on by pressing two buttons at the same time.

    Another important feature of the Chauvin Arnoux CA771 is its rugged design and capability to work in a huge range of different environments. It is suitable for both indoor and outdoor use and, with a maximum voltage of 1400V DC (1000V AC), it can be used for testing on LV circuits supplied by the mains or by individual generators. As certified by its type-S extended climatic class, the Chauvin Arnoux CA771 works at altitude, underground, in refrigeration units, in heated greenhouses and with vehicles. The device is waterproof and dust-proof to IP65 standard. Furthermore, the autotest function accelerates and simplifies the testing process.

    The Chauvin Arnoux CA771 is easy to use and the small, portable design makes it easy to transport. The ergonomic, moulded test probes aid handling and also protect against impacts and falls. These probes are removable, thereby adding further versatility whilst an integrated torch illuminates the measurement point. Overall, the Chauvin Arnoux CA771 is a versatile voltage detector with an impressive ability to work in varied and challenging environments.
