DETERMINING THE UNCERTAINTY OF MEASUREMENT WHEN TRANSFERRING A RANGE OF A MEASUREMENT SCALE |

- Abstract:
- Each recording of measurement values postulates the consistency of the realization and mapping of the measurement scale by the measuring device. The transfer of a measurement scale to a measuring or testing device at two or more data points is done in a linear space. A functional relationship between measurement scale and measured value realization is derived from regression analysis. A differentiation can be made between systematic, random and symmetric deviations between measurement realization and measurement scale. The systematic and symmetric deviations are compensated by using a correction function. All remaining deviations become part of the measurementuncertainty. The functional description of the uncertainty of measurement can be modelled using different models with symmetric and asymmetric limits of the interval.
