Feature Test & Measurement
Medstrom, an equipment and service supplier to the NHS, is using a Rigel Medical 62353 safety analyser to improve the electrical testing of thousands of medical devices located at sites around the UK
astle Donington-based Medstrom supplies and maintains electri- cally operated paediatric cots, bed movers, reactive therapy systems, patient beds, trolleys and carts among other items to hundreds of hospitals and healthcare facilities across the UK. These have to be regularly tested to ensure compliance with IEC 62353, the standard for in-service and after repair testing of medical electronic devices. The testing work is undertaken by Medstrom’s field service engineers who have been equipped with Rigel 62353 analysers, enabling them to check the electrical safety of equip- ment to ensure it is safe for use by both patients and staff.
The ability to be able to do this quickly and efficiently means that crit- ical safety tests are completed success- fully as an integral part of Medstrom’s after sales support and dedicated ser- vice team, saving time and boosting customer service levels. Twenty-four units have been sup- plied to date, combining the benefits of an automatic and manual tester with advanced data logging to provide improved asset management capability.
High praise
Darren Hunt, Medstrom’s technical training manager, was complimentary about the Rigel 62353 which, in addi- tion to enabling the company to comply with the requirements of IEC 62353 was easy to use and offered many beneficial features.
These include a long life battery which provides enough power to enable each analyser to complete more

than 60 tests per day without the need for constant re-charging.
Hunt commented, “The Rigel 62353 is a superb high performance instrument that works extremely well and delivers consistent results. It’s very intuitive, offering a single button test solution which engineers, who have busy service schedules to complete, really appreciate. “Test results are easily downloaded to our asset database while the memory and operating instructions are clear, straightforward and easy to navigate.” Hunt added that having the future- proof analysers is beneficial as there are plans to start using them for testing the safety of type B and BF applied parts fitted to life support equipment cur- rently in use at contracted accounts.
Capabilities
The Rigel 62353 analyser offers auto- matic sequencing, onboard data stor- age and data entry in a lightweight,
Measurement from a distance
Temperature Module connected to a test point, results can be viewed up to 20m away on a Fluke CNX Wireless Multimeter or a computer. All Fluke CNX modules can send live or logged measurements to a computer using a PC adapter. The Fluke CNX system allows users to place modules in hazardous or awkward places and then watch and record the readings from a safe distance. The CNX Wireless Multimeter can serve as the hub for the system and can show readings from four types of wireless modules - AC current clamp, iFlex current clamp, AC voltage and temperature. The Fluke CNX t3000 K-Type Wireless Temperature Module features a backlit LCD display

easy to carry enclosure. Improved bat- tery power provides extended operat- ing life while the instrument’s lightweight feature makes it practical and easy to transport from site to site. It can store and manage thousands of test records, which is beneficial to field service engineers moving quickly from site to site. Also, the capacity to customise test routines, visual inspec- tions and performance tests, which can be downloaded to and from a PC, improves in-service testing capacity. Other features include an easy to use facility for testing up to two indi- vidual Applied Parts from different modules or classes - for example, BF and CF class and either fully auto- matic, semi-automatic or manual test- ing. A full graphic LCD display has been incorporated with an integral alpha-numeric ABCD keyboard for quick and accurate operation. The analyser can be connected to
Rigel’s Med-eBase PC database software to provide enhanced electronic recording and management of testing programmes. Custom test routines can be created for testing specific medical devices before being uploaded to the analyser. Med-eBase verifies the status of electrical medical equipment in line with IEC 60601-1 and the new IEC62353 in-service safety testing standard. Test results can be stored on a local or remote database depending on the needs of individual biomedical service departments, enabling quick and easy access for service techni- cians and engineers via PCs.
