  • Patent number: 11635444
    Abstract: A feature amount extraction unit outputs, as a data series, a feature amount of time-series data of an oscillation frequency of an AC signal of an oscillation circuit until a certain time elapses from when a dispensing probe starts to be lowered. Then, a bubble contact determination processing unit determines whether a liquid level has been normally detected based on a correlation between a waveform of the data series of the feature amount and an abnormal waveform model. Further, based on a determination result, a second controller determines a deviation between a tip portion of the dispensing probe and the liquid level in a container and a factor of the deviation.
