Abstract
An objective of the present invention is to provide a vital information measurement device which measures vital information using a biosensor, with which it is possible to adjudicate more precisely whether a mounted biosensor is usable, and to alleviate inconsistency in measured values therefrom. Specifically, the present invention provides a vital information measurement device comprising: an input terminal to which a biosensor is connected; a voltage application unit which applies a voltage to the input terminal; an adjudication unit which is connected to the input terminal; a control unit which is connected to the adjudication unit; and a display unit which is connected to the control unit. The control unit causes the adjudication unit to carry out a first adjudication, a second adjudication, and a third adjudication.
