Chauvin Arnoux CA 6522 insulation tester content_copy

The Chauvin Arnoux CA 6522 is a digital insulation and continuity tester for precise measurement of insulation resistance up to 40 GΩ. The device is specifically designed for preventive maintenance in industry, to detect early damage or aging of insulation. It features a large, illuminated dual digital display with 2x 4000 digits and a logarithmic bargraph visually representing the insulation resistance. The display enables quick and accurate evaluation of measurement results, even in poorly lit environments.

Applications

The tester is used in industrial maintenance to ensure the electrical safety of plants, machines, and cables. It is suitable for testing motors, transformers, enclosures, and other electrical installations. Measurements are performed with test voltages of 250 V, 500 V, and 1000 V, with a maximum measurement range of 40 GΩ. The test voltages comply with standards and meet the requirements of IEC 61557-2, with conformity verified up to 2 GΩ.

Functions and equipment in detail

The device offers three measurement modes: Manual, locked (Lock), and Timer. The Timer mode allows measurement over a pre-set duration from 0:00 to 39:59 minutes, which is useful for standardized testing procedures. Continuity testing is performed with a test current of 200 mA, meeting the requirements of IEC 61557. An integrated lead resistance compensation up to 9.99 Ω increases measurement accuracy, especially with longer or high-resistance leads. An optical pass/fail indication via colors (green/red) supports quick evaluation of results.

Technology explained simply

Voltage measurement covers a range from 0.3 V to 700 V, with resolution of 0.1 V (up to 399.9 V) and 1 V (from 400 V). Measurement accuracy is ± (3 % + 2 pts) for voltage measurements and ± (2 % + 2 pts) for continuity testing. Input impedance is 400 kΩ. Frequency measurement is possible from 15.3 Hz to 800 Hz. Resistance measurements go up to 999 kΩ, capacitance up to 10 µF. The test current and actual test voltage are displayed on the secondary display, increasing measurement transparency.

Compatibility and accessories

Various accessories are available for use with the CA 6522, including a continuity test probe, a remote control probe with integrated work light, test leads with 4 mm connectors (1.5 m, 15 A, CAT IV, 1000 V, silicone), crocodile clips CAT IV-1000 V 15 A (red + black), test tips with 4 mm socket (CAT IV and CAT III 1000 V, PVC, red and black), and a transport bag. The remote control probe enables testing at hard-to-reach locations and illuminates the test point.

Mounting and installation

The device is compact and lightweight (850 g) with dimensions of 211 x 108 x 60 mm. It features a magnetic folding stand, allowing it to be attached to metallic surfaces, keeping hands free. Operation is via a function selector switch and a TEST button. Power supply is via 6 alkaline batteries (LR6/AA), enabling up to 1500 measurements for voltage measurement (U x 1 kΩ @ U, 5 s ON / 55 s OFF) or 3000 measurements for continuity testing (5 s ON / 55 s OFF). Automatic shutdown occurs after 5 minutes, but can be disabled.

Advantages in operation

The CA 6522 offers high user-friendliness due to its ergonomic design, robust construction according to 600 V CAT IV, and protection rating IP54/IK04. The integrated software function ΔREL shows deviation from a reference value, which is helpful for comparative measurements. Storage of up to 300 measurement values in the device enables later evaluation. For models with Bluetooth connection, storage capacity is extended to 1300 measurements. The software Megohmmeter Transfer (MEG) enables real-time display of measurement values on a PC and data transfer. The optional software DataView® allows creation of test reports. Measurement is performed with a discharge time of less than 2 seconds per microfarad at 25 V, increasing safety when discharging capacitors. The devices are designed for industrial environments and comply with standards IEC 61557-1, -2, -4 and -10, as well as IEC 61326-1 and IEC 61010-1, -2-030.

Note: Batteries are not included in the delivery scope.
