Messfunktion

Messfunktion refers to a mathematical function that relates the measured value of a physical quantity to its true value. In metrology, it is crucial for understanding and quantifying measurement uncertainties and for calibrating measuring instruments. The messfunktion can be represented as a curve, a table, or a mathematical equation. Ideally, a messfunktion would be linear, meaning that the measured value is directly proportional to the true value. However, in practice, measuring instruments often exhibit non-linearities, biases, or drift, which deviate from this ideal behavior.

Understanding the messfunktion of a particular instrument or measurement system allows for corrections to be applied to the raw data, leading to more accurate and reliable results. This is particularly important in fields where precise measurements are critical, such as scientific research, engineering, and manufacturing. Calibration procedures are designed to determine the messfunktion of an instrument by comparing its readings to known standards. The resulting messfunktion can then be used to compensate for any systematic errors. Statistical methods are often employed to characterize the messfunktion and its associated uncertainties, providing a comprehensive understanding of the measurement process.
