Abstract

PURPOSE: To use the lasted obtained value when the data is included within the both range limit, and to use the value obtained at the present time when the data is not included within the both range of limit by setting the permissible limits on the present and the several times data of the past.
CONSTITUTION: For checking the noise of each component, the data Xi measured at this time and two ones Xi-1, Xi-2 measured in the past are used. As the method, the permissible limits of ±α% are given to the two Xi-1, Xi-2 compensated 100% respectively. When the data Xi-2 at the last but one and Xi-1 at the last time are in the mutual permissible limits and they are not in the limits of Xi±α, the data Xi-1 is used in place of the data Xi. Also, when each data is not in the respective permissible limits of the data Xi, Xi-1, Xi-2, the data Xi at this time is used.
