The CA 6011 continuity tester from Chauvin Arnoux is a measuring instrument specifically designed for the daily testing of protective, earthing, and equipotential bonding conductors. It is used for the systematic verification of low resistance in earthing connections in electrical devices, equipment, and installations, and complies with the requirements of standard IEC/EN 61557-4. The device is designed for recurring inspections, which account for more than 80 % of all tests in practice, and offers an ergonomic, user-friendly, and reliable solution for this purpose.

Applications

The continuity tester is used to check the electrical connection of protective conductors, earthing systems, and equipotential bonding conductors. This includes, for example, testing the earthing of lightning protection systems, checking the conductivity of Faraday cages, and verifying the low resistance of mass connections. The application is in electrical installation, facility management, industry, and maintenance of electrical installations.

Functions and Equipment in Detail

The device features a measurement range of 0.00 Ω to 20.00 Ω with a resolution of 10 mΩ. Measurement is performed with a test current of 200 mA up to 2.00 Ω and 20 mA above 2.00 Ω, with polarity automatically switched to minimize measurement errors caused by thermal voltages. The continuity threshold is programmable and can be set to 1 Ω or 2 Ω, depending on local regulations. Line resistance compensation is activated and effective for resistances below 5 Ω.

Technology Explained Simply

The device display is a 2000-point display with dual-color backlighting, clearly and legibly showing the measurement values. Conformity or non-conformity of the test is indicated by a configurable visual, acoustic, or vibrating signal. The vibrating function reduces environmental disturbances and relieves the user, especially during longer tests. The automatic standby mode turns off the device after 10 minutes of inactivity and can be deactivated. The autonomy is up to 30,000 measurements in real use, with 4,500 measurements achieved according to IEC 61557-4 protocol.

Compatibility and Accessories

The device is supplied with a cable roller for 30 m of cable, facilitating transport and handling. Additionally, a shoulder strap, waist strap, and elastic wrist loop are included to optimize weight distribution and enhance carrying comfort. The accessory set for continuity testing includes all necessary components for the test.

Mounting and Installation

Mounting of the device is done by simply connecting the test leads to the contacts to be tested. Operation is via four buttons on the front panel, providing direct access to all functions. Power supply is via four 1.5 V AA/LR6 batteries.

Advantages in Operation

The CA 6011 offers high operational safety and reliability for daily testing. The clear display, flexible signaling, and ergonomic design ensure efficient and pleasant work. The long operating life and easy handling make the device particularly suitable for practical use. The measurements comply with standards IEC/EN 60364, NF C 15-100, VDE 100, and current legislation.

Delivery Contents

The device is delivered complete with cable roller (30 m cable), shoulder strap, waist strap, elastic wrist loop, and the complete accessory set for continuity testing. The delivery includes safety data sheet, quick guide, operating manual, and test confirmation.
