Summary

Students learn to use all types of measuring instruments such as analog, digital as well as virtual ones, which they will even be able to try to get together. Different methods will be able to measure basic electrical quantities and passive components. An integral part of each measurement is the knowledge of quantifying the uncertainty of measurement.
