The analog insulation tester C.A 6503 from Chauvin Arnoux is a portable measuring instrument for testing high insulation resistances in electrical installations. It features a hand-cranked inductor, enabling independent power supply without mains connection, and is specifically designed for use on construction sites and in harsh environments. The device is suitable for maintenance and testing of cables, motors, RCDs, transformers, as well as for conformity testing of electrical installations according to applicable standards in industrial and residential applications.

Applications

The insulation tester is used in the electrical and telecommunications industry to check the insulation quality of electrical installations. It is particularly suitable for maintenance and servicing of systems where reliable insulation is critical. Applications include industrial and residential installations, where voltage-free testing and measurement of high resistances are required.

Functions and Equipment in Detail

The device offers three fixed test voltages: 250 V DC, 500 V DC, and 1000 V DC. The measurement range extends from 1 to 5000 MΩ, with an accuracy of 2.5 % of full scale. Automatic range switching ensures the device automatically adjusts to the correct measurement range. An integrated voltage-free test and a control lamp indicate correct measurement conditions. An additional clamp minimizes measurement errors caused by leakage currents, improving measurement accuracy.

Technology Explained Simply

Power is supplied via a hand-cranked inductor, which generates a stable test voltage using mechanical energy (crank operation). This makes the device independent of mains power and allows immediate use at any location. The display is analog, enabling direct reading of the measurement value. The protection rating is IP 52 without cover and IP 54 with cover, providing dust and splash water protection. Electrical safety complies with CEI 61010 standard, with 600 V CAT II and 300 V CAT III, allowing use in electrical installations of corresponding categories.

Compatibility and Accessories

Compatible accessories are available for use with the C.A 6503 insulation tester, including a 200 mA fuse (600 V / 6x32 mm) and a carrying case. These components support safe and organized operation of the device, especially during mobile applications.

Mounting and Installation

The device is designed as a portable measuring instrument and requires no mounting. It is directly connected to the installation under test, with the crank operated to generate power. The connection clamps ensure a secure and reliable connection.

Operational Advantages

The C.A 6503 offers high operational safety due to its robust construction and mains-independent power supply. Immediate readiness for use, automatic range switching, and integrated voltage-free test increase efficiency and safety during testing. The analog display allows for quick and direct evaluation of the measurement result. The IP 54 protection rating (with cover) makes the device suitable for outdoor use, provided there is no direct water exposure.
