Ultimately, every measurement is based on a physical effect. Students learn how measurement technology makes use of these effects and minimises interfering influences that distort the result through a clever measurement setup. The second focus is on analogue and digital measured value processing, including error analysis and mathematical evaluation on the computer. In a third focus, students will familiarise themselves with dynamic systems from a laboratory perspective and in this way complete the knowledge of systems theory taught in the measurement technology lecture.

The exercises deal with so-called electrical measurement technology, whereby the focus is mainly on the acquisition of non-electrical variables.
