Applied Technology Test & Measurement
The STM/L performs 500V insulation tests using a DC test voltage, which can be used instead of a flash test when required, as well as completing earth bond, polarity and conti- nuity, and load and operation testing. And once testing is complete, a test and tag label is produced confirming the product has been fully tested and the results recorded and downloaded to a central database. Using the STM/L enables Jim Lawrence to undertake fast and accurate automatic testing to ensure its products are safe to use after leaving the factory and avoid the risk of damage during the testing process in line with the company’s quality control programme.
Taking a shine to testing
Jim Lawrence, a family owned business spe- cialising in forged iron and solid brass light- ing products, is using the Clare Safetest Manufacturing/Luminaire (STM/L) digital electrical safety tester from Seaward to improve compliance testing during produc- tion at its Suffolk factory. All of Jim Lawrence’s products, which include a range of wall, pendant, spot and pic- ture lights, are available via its showroom in
Hadleigh near Ipswich or its online shop to both UK and international customers. They are tested in accordance with annex Q of the Luminaire Standard (BS EN 60598) as part of the company’s quality assurance guarantee. In a move to further strengthen this posi- tion, Jim Lawrence is using four STM/L units at its manufacturing facility, where hundreds of handmade lighting units are produced and tested each week.
Dick Kirk, technical manager at Jim Lawrence, commented, “The STM/L is a good tester which allows us to comply with the relevant standards and our own quality control programme. “It’s comprehensive and robust, and has many easy to use and beneficial features like test and tag. It’s playing an important role in ensuring our products perform to the highest safety standards and is proving its worth on the production line.” All Jim Lawrence’s test requirements can be pre-programmed into the STM/L using a QWERTY keypad and following the on- screen user instructions. All these tests are individually user selectable and an internal memory has the capacity to store the results of 6,000 tests. Seaward
