PROBLEM TO BE SOLVED: To appropriately detect abnormality of a measuring instrument and to spread information of inspection and failures to a plant operator at more suitable time.SOLUTION: In an abnormality measuring instrument determination system for measuring the same quantity to be measured in a plant by a first measuring instrument 100 and a second measuring instrument 200, comparing a measurement output of the first measuring instrument 100 with a measurement output of the second measuring instrument 200 and determining abnormality of the measuring instruments, the abnormality of the measuring instruments is determined depending on a difference between a change rate of measurement outputs of the first measuring instrument 100 and a change rate of the measurement outputs of the second measuring instrument 200. |
