<p>PROBLEM TO BE SOLVED: To realize a method, easy to use and understand, for correcting a signal transmitted from a sub-measuring unit with respect to a signal transmitted from a main measuring unit by establishing a correction model based on a plurality of correcting products having known characteristics and processing a standardized signal obtained from a product of same type as the correcting product. SOLUTION: At first, standardized signals transmitted from main and sub- measuring units are decomposed into grades. A decomposition method for recalculating the original signal from elements obtained through decomposition is selected using a reverse format function. A mathematical relationship is established among the coefficients obtained through grade decomposition of signals transmitted from the main and sub-measuring units. Subsequently, correction coefficients of the parameters obtained through decomposition of signal from sub-measuring unit with respect to the parameters obtained through decomposition of signal from main measuring unit are determined using a mathematical relationship established in the preceding stage and stored in the form of a correction matrix.</p> |
