WEB-BASED LABORATORY TRAINING ON ELECTRICAL MEASUREMENT SYSTEMS

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 a real measurement action and not output of a simulation. Web-based instrumentation supports teaching only successfully, if the user understands the basic functional principles of the instruments already to some degree. In addition, the teaching process has to comprise a discussion of the measured data to achieve an understanding of how a reliable measurement result is obtained. Therefore, the electrical internet-laboratory is integrated in a web-based training environment on electrical measurement systems.

EUROMET: ITS OBJECTIVES AND ACHIEVEMENTS

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.

NATIONAL MEASUREMENT LABORATORY AND ITS ROLE IN THE AUSTRALIAN STANDARDS AND CONFORMANCE SYSTEM

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.

CAPABLE PROCESSES BY OPTICAL METROLOGY

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 surface inspection as well as for analysis of dynamic processes. Due to their ability for miniaturisation optical sensors are well suited for the direct use in manufacturing systems and production environment. Thus, the goal of this article is to illustrate the efficient use of optical measurement systems in different manufacturing processes. Detailed examples show that optical metrology is a key factor for sucessful manufacturing. Finally, perspectives and trends of optical measurement techniques in the field of production technology will be presented.
