    The accreditation requirements, like those for any other NAMAS accreditation, must be in accordance with the NAMAS accreditation standard M10 and NAMAS regulations M11, but in addition, the system software must be validated. The author discusses the principles of NAMAS accreditations of automated systems and system software View full abstract»

    Automated measurements are performed using a variety of equipment which varies in complexity from a `simple' digital voltmeter connected to a printer right up to complex ATE (automatic test equipment) occupying several racks and capable of performing several sets of related measurements at the same time. ATE systems have evolved in response to an ever more competitive market-place enabling fewer and lesser skilled people to perform more tasks more effectively. Another of the principle strengths of ATE systems is the ability to perform vast quantities of sophisticated (and possibly tedious) measurements by simply adding a few additional lines of code to the program. Whilst this produces an ideal situation because each additional measurement performed reduces the risk of a potentially `defective' product passing through it will, if allowed to run unchecked, eventually impose its own limits upon the quantity of products being tested and sold. To address this, the test process and the quantity of measurements performed need to be reviewed periodically to ensure that both productivity and quality targets continue to be achieved. These principles are illustrated using an example View full abstract»

    The introduction of automated calibration and measurement facilities used in the right environment can increase the efficiency of many routine calibrations, increases the quality of calibration and can enable direct production of certificates without the traditional intervening stages. The right software package is an important decision both for now and for development in the future. There are many points to look at when choosing a package and some of the more important ones are listed below. It is however very easy to buy more features than you need and end up with a system which is difficult to use. Try to keep in mind just what it is you want to do, and make sure the software you are buying can do it properly. If you are looking for a system that can calibrate large volumes of instruments above all look for a system which is easy to use. A complex system will slow down a skilled engineer and make it impossible for a technician to use View full abstract»

    This paper attempts to convey some of the issues associated with a feasibility study into the use of artificial intelligence (AI) in a specific application area. The area in question involves the aid to bench engineers in a working environment. Engineers in general, are quite used to applying new and complicated technological concepts to help them solve difficult problems and therefore it was felt that this area of study involved ideal candidates for the utilisation of AI View full abstract»
