Abstract
According to an aspect of the present invention, there is provided an automatic analyzer that detects a liquid level by using an electrostatic capacity system. Feature values are extracted from time-series oscillating frequency data of an alternating current signal that is output by an oscillation circuit in a period from a time point at which a dispensing probe starts moving downward till a time point at which a certain period of time has elapsed. On the basis of the feature values from the time-series oscillating frequency data, it is determined whether or not the liquid level in a container has been detected properly, by using different methods. Whether a gap is present between the tip portion of the dispensing probe and the liquid level in the container and a reason for the gap are determined from a combination of multiple determination results obtained by using the methods.
