Abstract
An arithmetic unit for correcting a detection output of a detector for a mechanical error of the detector in accordance with a predetermined input/output characteristic (straight line) is provided. When a digital output of the detector exceeds an upper limit value stored in a main memory, the digital output becomes a new upper limit value. From a virtual line which passes through the new upper limit value and which is parallel to the straight line, a new lower limit value is obtained. A corrected operation output is obtained in accordance with a new input/output characteristic of the detector based on the new upper limit value and the new lower limit value. Thus, the correction accuracy is improved.
