In a measurement situation information storage unit (25a), a plurality of sets of measurement situation information for identifying a measurement situation in which predetermined measurement is performed on a measurement target are stored in association with time periods. A measurement processing unit (26) executes measurement on the measurement target (10). A display unit (37) selects, from among the plurality of sets of measurement situation information, a set of measurement situation information corresponding to the measurement operation timing based on the time (31) of the measurement operation timing or based on processing results obtained as a result of execution of measurement by the measurement processing unit, and causes a display (22) to show the selected set of measurement situation information in a manner distinguishable from other measurement situation information.
