An automatic analyzer (100) includes: a storage unit (21b) that stores various parameters of the automatic analyzer (100) in association with each of elevations used in the automatic analyzers (100), the parameters being optimized for each of the elevations; an input unit (21d) that acquires information of an elevation at which the automatic analyzer (100) is provided; and a controller (21a) that reads the parameters stored in the storage unit (21b) and sets the read parameters to the automatic analyzer (100) based on the elevation acquired by the input unit (21d). As a result, various parameters can be easily adjusted according to a usage environment of the device.
