Abstract: The biological particle counter has a first circuit configured to generate a first signal corresponding to fluorescence from the biological particle in response to irradiated light. A measurement value obtainer is configured to obtain, from the biological particle counter, a voltage value of the first signal for a calibration particle obtained in such a manner that a fluorescence agent infiltrates into a surface of a polystyrene particle. A circuit adjuster is configured to use reference data indicating a correspondence relation between a fluorescence agent parameter value correlated to the content of the fluorescence agent and a reference voltage value of the first signal corresponding to the fluorescence agent parameter value, thereby specifying the reference voltage value of the first signal corresponding to the fluorescence agent parameter value for the calibration particle. The first circuit is adjusted such that the voltage value of the first signal for the calibration particle reaches the reference voltage value.
