ABSTRACT:
The method of self-calibrating for a sensor without using an additional device by using data sampling, an approximate value of linear errors obtained by performing the numerical integration of approximate values of a linear-error derivative, correcting the approximate value of the input value at each sampling point, and repeating the processing for correcting the approximate value of the linear error by necessary times.
