Calibration Calibration Result from Repeated Experiment Thermocouple Calibration Just as in estimation or prediction if the calibration experiment were repeated the results would vary slighly due to the randomness in the data and the need to sample a limited amount of data from the process. This means that an uncertainty statement that quantifies how much the results of a particular calibration could vary due to randomness is necessary. The plot below shows what would happen if the thermocouple calibration were repeated under conditions identical to the first experiment. http div898 handbook pmd section1 2 of 4 5 1 2006 10 21 53 AM . Calibration Calibration Uncertainty Again as with prediction the data used to fit the process model can also be used to determine the uncertainty in the calibration. Both the variation in the estimated model parameters and in the new voltage observation need to be accounted for. This is similar to uncertainty for the prediction of a new measurement. In fact calibration intervals are computed by solving for the predictor variable value in the formulas for a prediction interval end points. The plot below shows a 99 calibration interval for the original calibration data used in the first plot on this page. The area of interest in the plot has been magnified so the endpoints of the interval can be visually differentiated. The calibration interval is - degrees Celsius. http div898 handbook pmd section1 3 of 4 5 1 2006 10 21 53 AM . Calibration Temperature In almost all calibration applications the ultimate quantity of interest is the true value of the primary-scale measurement method associated with a measurement made on the secondary scale. As a result there are no analogs of the prediction interval or tolerance interval in calibration.
