Abstract
The automatic analyzer includes: a liquid dispensing mechanism that performs suction of a liquid; a pressure sensor that measures a change of an internal pressure of a probe provided at the liquid dispensing mechanism; a determination section that determines whether the suction of the liquid by the probe is normal suction or air suction abnormality; an analysis section; a storage section that stores a cumulative number of times of air suction abnormality per liquid and an allowable cumulative number for the cumulative number of times of air suction abnormality; and a controller that exercises operation control over the liquid dispensing mechanism, the determination section, and the analysis section. The controller exercises control such that the cumulative number of times of air suction abnormality is updated and the updated cumulative number is stored in the storage section even if the air suction abnormality occurs non-consecutively.
