<p>PROBLEM TO BE SOLVED: To prevent a human error from being caused by making it possible to correct a detector only by the operation of a detector-side operator and making the plant monitor device decide whether or not correction data is good. SOLUTION: A correction data generating means 31a of a detector correcting means 31 inputs an engineering unit signal as correction data and calculate a detector error by comparing this data with a reference value based upon setting information from a terminal device interface part 29, and a correction data decision means 31b compares it with a previously set error permissible value to decide whether or not the detector error is within the permissible range and displays the result on a terminal device 27 detector correction. Further, a correction history data storage means 33 stores the generated detector error data and correction data as a correction history. Further, correction data having a large detector error is corrected by a detector error correcting means 21 by using data for detector error correction and this data for detector error correction is set and altered by a data correcting means 25.</p> |
