摘要： An abnormality determination apparatus includes a data acquisition part that acquires position data indicating a plurality of positions to be measured of a standard gage used in a coordinate measuring apparatus, in association with apparatus identification information for identifying the coordinate measuring apparatus, a generation part that generates distance data indicating a distance to be measured that is a distance between the plurality of positions to be measured indicated by the position data, a storage that stores an appropriate range in which the distance data is determined to be appropriate, and a determination part that determines whether there is an abnormality in the coordinate measuring apparatus on the basis of whether or not the distance to be measured indicated by the distance data is included in the appropriate range, and outputs a determination result in association with the apparatus identification information.
