Learning outcomes:
After successfully completing this course, students will be:  able to calculate the rootmeansquare value of any timedependent quantity,  able to determine undulating currents and voltages from the separate measurement of zero frequency and periodic quantities,  familiar with the definitions for mean value, rectified value, rootmeansquare value, form factor and peak factor and be able to explain their meaning.  able to identify the problems that can arise from the use of certain measuring elements/instruments in connection with the measurement of timevarying electrical quantities and take them into account in measurements,  able to calculate field and performance quantities in the pseudounits Bel, Decibel and Neper forward and backward,  able to calculate with quantities in the abovementioned pseudounits,  able to outline the basic structure of a spectrum analyzer and outline the significance of its individual components,  able use the basic functions of a spectrum analyzer, including the appropriate selection and adjustment of e.g. the center frequency and frequency range, the vertical resolution, the resolution bandwidth, the discriminator, the video bandwidth,  able to safely use instrument transformers for current and voltage measurements and quantify their measurement errors,  able to measure or calculate unknown AC resistances using various AC bridges and/or oscilloscopes,  able to calculate loss factors and qualities of alternating current resistances and identify them by way of measurement,  able to explain how modern LCR meters work,  able to to determine the mutual inductance of two coupled coils by measurement,  able to carry out power measurements (apparent, reactive and active power) in a single and threephase system (with or without neutral conductor),  able to calculate the power in corresponding singlephase and threephase networks,  able to describe how a Ferraris meter works,  able to name, compare and roughly evaluate common methods of temperature measurement and their mode of operation to ascertain which method is suitable for a specific purpose,  able to measure static magnetic fields using a field coil and integrator (strength and direction),  able to use acceleration sensors to measure inclination and rotational speed,  able to calibrate sensors,  able to interpret their measurement results and explain the corresponding calculations.  able to independently plan, organize and carry out measurement tasks in small groups,  able to operate more complex measuring equipment,

Teaching methods/Media:
Slides, lab guides, exercises and videos; all materials can be accessed electronically by students. The module combines lecture and lab components. The lab component consists of 5 compulsory sessions. Experiments will be carried out in groups of two, preparation for the lab sessions will be checked individually. A report must be written for each of the lab experiments. These reports must be personally presented to the lecturer/supervisor. In the lab sessions, students will carry out various measuring tasks on real objects and devices without demonstration, but according to instructions. A supervisor will be available to assist them, if needed.
