The Chauvin Arnoux CA 6534 is a digital insulation and continuity tester for use in electronics and specific applications such as ESD testing. The device enables measurement of insulation resistances up to 50 GΩ and offers five fixed test voltages: 10 V, 25 V, 100 V, 250 V, and 500 V. The test voltages of 10 V and 100 V are particularly suitable for ESD testing in electronics, as they require low voltages to avoid damaging sensitive components. Measurement of floor coverings and installed flooring is possible with optional probes, supporting use in electronics and manufacturing technology.

Applications

The CA 6534 is designed for applications in electronics, particularly for ESD testing. It is also suitable for testing insulation resistance in electrical installations and devices, with the five test voltages enabling flexible adaptation to different requirements. The continuity test with 200 mA or 20 mA test current complies with IEC 61557 and is suitable for testing circuits and wiring. The lead resistance compensation up to 9.99 Ω reduces measurement errors caused by the resistance of the used leads.

Functions and Equipment in Detail

The device offers several operating modes: manual testing, locked testing (Lock), and testing with pre-set duration (Timer). The ΔREL function displays the deviation from a stored reference value, showing the difference both numerically and in percentage. This facilitates comparability of measurements over time. The optical pass/fail indication via colors (green/red) supports quick evaluation of results. For continuity testing, an active protection is integrated, which detects existing voltages and disables the function to prevent fuse blowouts.

Technology Explained Simply

The CA 6534 measures insulation resistance in the range of 2 kΩ to 50 GΩ, depending on the selected test voltage. At 10 V, the measurement range is 2 kΩ to 1 GΩ; at 500 V, it extends to 50 GΩ. The accuracy of insulation measurement is ± (3 % + 2 pts). The test voltage can be selected in five fixed steps, with voltage values displayed precisely (± (3 % + 3 pts)). Test currents range from 0.01 µA to 2.000 mA, with accuracy of ± (10 % + 3 pts). Measurements are performed in DC and in the frequency range of 15.3 Hz to 800 Hz. The input impedance is 400 kΩ.

Compatibility and Accessories

Various accessories are available to extend functionality: crocodile clips (alligator clips) 20 A CAT III 1000 V red + black, probe for continuity testing, remote control probe No. 3, test leads with 4 mm straight/angled plugs (1.5 m, 15 A, CAT IV, 1000 V, silicone, red + black), 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, carrying case, and the DataView software. The remote control probe with integrated lamp allows measurements in dark environments, with the illuminated display of the device showing the results.

Mounting and Installation

The device is compact and ergonomically designed with dimensions of 211 x 108 x 60 mm and a weight of 850 g. The magnetic folding stand allows attachment to metal surfaces, freeing both hands for measurement. The large illuminated dual digital display shows the measurement value as well as additional parameters such as test voltage, test current, and timer. The logarithmic bar graph supports visual evaluation of insulation resistance.

Advantages in Operation

The CA 6534 offers high measurement accuracy and reliability for insulation and continuity testing. The integrated Bluetooth® interface (Class II) enables real-time data transmission and analysis. Up to 1300 measurement values can be stored in the device. The Megohmmeter Transfer (MEG) software is included as standard and allows starting the test from a PC, graphical display of measurement results, and data transfer. The optional DataView® software enables creation of individual test reports with indication of test location and operator. Power supply is via 6 LR6 (AA) batteries, with autonomy of 1,500 insulation measurements (5 s ON / 55 s OFF) and 3,000 continuity measurements (5 s ON / 55 s OFF). The automatic shutdown after 5 minutes is deactivatable. The device complies with protection class IP54 and mechanical strength IK04, making it suitable for demanding environments. Compliance with standards IEC 61557 parts 1, 2, 4, and 10, as well as IEC 61326-1 and IEC 61010-1/-2-030 (600 V CAT IV) ensures electrical safety and EMC compliance. Batteries are not included in the delivery scope.
