A method of using a measuring instrument of unknown calibration in such a way as to correct the calibration. The method includes taking a measurement with the instrument, storing the measurement in a data storage medium, and correcting the measurement at a later time based on a determination of the amount of error in the measuring instrument. The method may also be used to remove error that is present as a result of inaccuracies that are present in the data gathering instrument. This method can be used in a write variety of instruments that are used to take measurements, but is particularly useful for medical instruments.
