A biometric apparatus includes a calculation device that processes first time series data from a first measuring device and second time series data from a second measuring device； a display device that displays the time series data； a trigger signal generator that generates one or more trigger signals； and an input unit, wherein the calculation device determines one or more specific intervals of the first time series data based on the one or more trigger signals； configures a classification reference for classifying time series data in the one or more specific intervals using the time series data in a first specific interval using an input signal as a trigger； classifies the second time series data for the one or more specific intervals using a result of classifying the first time series data based on the classification reference； and displays a classification result of the second time series data.
