Rigel Medical has introduced an upgraded version of its dedicated tester for the in-service and post-repair safety testing of medical electronic devices in line with the standards required by IEC 62353.
In line with changes in test requirements from manufacturers of 24V DC and 48V DC operated medical equipment such as operating tables and portable lighting installations, the new Rigel 62353 Plus tester is equipped with an extended range of insulation test voltages between 50V DC to 500V DC.
As a result, four separate insulation test voltages are now provided at 50V DC, 100 VDC, 250V DC and 500 V DC to give the latest tester even more flexibility in meeting the routine safety testing needs of medical devices in line with the internationally recognised in-service test standard.
Other special design features include an earth bond “zap” circuit that makes use of preconditioning the contact resistance by using a high current, low energy pre-pulse.
In addition, the new tester can measure and warn of secondary earth paths which are common in hospitals and which may seriously affect the validity of leakage measurements if undetected, potentially leading to false positives and passing medical equipment as electrically safe when in fact they are not.
Improved battery power reduces the downtime between testing and other features include an easy-to-use facility for testing up to two individual Applied Parts from different modules or classes e.g. BF and CF class, in either fully automatic, semi-automatic or manual test modes.
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 to PC-based asset management and test records databases for maximum traceability.
The new Rigel 62353 Plus analyser tests in full compliance with IEC 62353 and NFPA 99 or AS/NZ3551 respective local versions.
The new instrument forms part of a comprehensive range of advanced safety analysers, patient simulators, testers and accessories from Rigel Medical, part of the Seaward Group.
