An embodiment of a method for a determination, section after section, of a parameter-dependent correction value approximation course includes determining a first measurement signal value with a first parameter value associated with a sensor arrangement when the first parameter value fullfils a predetermined condition or a trigger condition is fulfilled, changing the first parameter value to obtain a second parameter value, determining a second signal value with the second parameter value and determining a second partial section of the correction value approximation course for a second parameter range based on a functional connection describing the second partial section, the first parameter value, the second parameter value, the first measurement signal value, the second measurement signal value and an initial correction value.
