It is possible to perform abnormality diagnosis of a matching circuit that matches electric impedance between a drive circuit and an ultrasonic element. An automated analysis device irradiates a reaction liquid in a reaction container with ultrasonic waves to stir the reaction liquid, the automated analysis device including: a piezoelectric element that irradiates the reaction liquid with ultrasonic waves; a power supply unit that supplies electric energy for driving the piezoelectric element; a matching circuit that matches impedance between the piezoelectric element and the power supply unit; and a diagnostic circuit that measures a voltage or a current on an input side of the matching circuit and a voltage or a current on an output side of the matching circuit, and diagnoses abnormality of the matching circuit based on the voltage or the current on the input side and the voltage or the current on the output side.
An automated analysis device that irradiates a specimen and a reagent in a reaction container with an ultrasonic wave to stir the specimen and the reagent, the automated analysis device comprising:
An abnormality diagnosis method for a matching circuit that matches impedance between an ultrasonic element and a drive circuit, the ultrasonic element irradiating a specimen and a reagent in a reaction container with an ultrasonic wave, the drive circuit supplying electric energy for driving the ultrasonic element, the method comprising:
