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. For the full article click here
