Compared with the correct value for the measured variable — the input [...] input variable for the measuring device — the measured value is associated with errors caused, for example, by an unfavourable arrangement of the sensor or the characteristics of the measuring device. A distinction

since errors occurring between the measuring position and the comparison position — particularly measuring inaccuracies — will have a real impact on the controlled variable . Given this, the measuring device
