Abstract
To suppress and compensate influences of disturbance variables, a method of calibrating a sensor is disclosed, in which at most as many so-called influence variables influencing the measuring result are considered as measurable quantities are detected by the sensor, the set of the influence variables being composed of at least one disturbance variable influencing the measurement and at least one target quantity to be determined from the measurable quantities. The method in accordance with the invention is characterized in that several values of the target quantity and several states characterized by the disturbance variable are defined, that for all combinations of defined values of the target quantity with defined states the corresponding values of the measurable quantities are acquired, that from one each of the defined values of the target quantity and the corresponding values of the measurable quantity respectively a set of coefficients is determined for all defined states, and that the sets of coefficients are associated each to the corresponding value of the target quantity and stored.
