And, with the number of measurement omissions, 22b, as +1, and the number of remaining omissions, 22d, as -1, DELTA heat displacement position, 22h, is added to a heat displacement 22e. Accordingly, even in the working with measurement omitted, the correction is made on the basis of past data. Then, when the number of remaining omissions, 22d, is 0, a measurement command to the detector position 23g and the correction are made and the measurement history 22g is renewed. Calculation is made of a measurement omission determination and of DELTA heat displacement 22h.
