An upgraded dedicated tester meets international standards for in-service and post-repair safety testing of 24 V and 48 V DC medical electronic devices.

The Rigel 62353 Plus tester offers a range of tests without the need for mains power, and is thus capable of conducting battery-powered insulation and earth/ground bond testing in complete freedom during the installation process, as well as eliminating the inconvenience of trailing mains cables. The tester comes with four separate insulation test voltages (50 V DC, 100 V DC, 250 V DC, and 500 V DC), providing more flexibility in meeting routine safety testing for increasingly popular equipment running on 24 V DC and 48 V DC, such as operating tables, lights, and mobile X-rays.

Other design features include an earth bond “zap” circuit that preconditions contact resistance by using a high current, low energy pre-pulse. In addition, the upgraded tester can measure and warn of secondary earth paths (common in hospitals) and which may seriously affect the validity of leakage measurements if undetected. The automatic warning ensures users are made aware when invalid readings are made, providing correct and accurate test results every time.

The comprehensive testing capability of the safety tester is supported by a large internal memory for the storage of test results, with stored test data being transferred via Bluetooth technology to a PC-based asset management and test records databases for maximum traceability. In conjunction with the comprehensive Med-eBase database software, creation of test sequences and the ability to produce professional test certificates is simplified.

The tester allows testing of up to two individual applied parts from different modules in fully automatic, semiautomatic, or manual test modes. The Rigel 62353 Plus tester is a product of Rigel Medical (Durham, United Kingdom), and is in line with the internationally recognized IEC 62353, NFPA 99, and AN/NZ3551 in-service test standards.
