<P>PROBLEM TO BE SOLVED: To provide a measuring device capable of maintaining normal measurement by automatically detecting an operation defect of a movable part. <P>SOLUTION: The measuring device includes a load applying means 110 of applying a load varying a weighing signal to a weighing means 21; a weighing signal storage part 112 which storing the weighing signal from the weighing means 21 when the load applying means 110 applies the load to the weighing means 21; an abnormality determination part 114 which stores the weighing signal storage part 112 with the weighing signal from the weighing means 21 by previously applying a load to the weighing means 21 by the load applying means 110 as a normal-time weighing signal, stores the weighing signal storage part 112 with the weighing signal from the weighing means 21 by applying a load to the weighing means 21 by the load applying means 110 during diagnosis, and compares waveforms of the normal-time weighing signal and the weighing signal for diagnosis with each other to diagnose whether the weighing signal for diagnosis has an abnormal value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
