The system is based on a client-server architecture. Clients accede to laboratory through a standard web-browser, without plug-ins. Exploiting HTML pages, ASP scripting and software drivers, resident on the web-server, users are able to select the experience that they want to run, to manage the instrumentation that reside in laboratory, and to reconfigure measure’s object according to parameters that they want to test. The instruments reconfigurability and measurement objects is performed by switch/relays module and to keep to reality as much as possible, every result is returned to client...
In the educational process of teaching engineers one important part is to bridge the gap between theory (functional principle, model….) and real world (hardware, devices…). By learning e.g. how to use an oscilloscope in a real application the functional principle is accompanied by an evaluation of the measurement results. In our web-based electrical laboratory www.internetlabor.ch the user trains himself how to push the right button on a real oscilloscope by a mouse click via his internet browser. The measured data downloaded subsequently are the product of a real hardware operation based on...
EUROMET, the European organisation of National Metrology Institutes, promotes the coordination of metrological activities and services in order to achieve higher efficiency. A key task of EUROMET is to provide the necessary framework to allow for the mutual recognition and acceptance of calibration certificates. This paper describes the objectives, structure and key tasks of EUROMET.
The principal, and generally exclusive role of a national measurement institute (NMI) is the delivery of metrology. In addition to the maintenance of measurement standards, the delivery of metrology involves providing access to those standards for all with an interest in measurement, as well as responding to demands for improvements in the standards and their dissemination. It also calls for the transfer of knowledge and information in a variety of ways to ensure the use of appropriate technology and the adoption of best measurement practice. As the UK’s national measurement institute, the...
The paper gives a brief introduction to the National Measurement Laboratory (NML), Australia's premier institution for measurement science and technology. A particular emphasis is placed on the role NML plays as a key element in the national standards and conformance infrastructure.
Today, optical metrology is already an essential factor for manufacturing processes. Within different tasks optical metrology guarantees increasing capability of processes. Optical measurement techniques secure fast and precise process steps. Therefore, optical methods integrated into manufacturing lines are well suited for measurement tasks. Their setups are modular and they have defined interfaces to the electronic periphery. Further, optical measurement techniques are very versatile, flexible and most accurate. They are used more and more for noncontact distance measurement, shape and...
