Abstract
A device is used for precisely measuring an electrocardiographic wave and sphygmus. The device displays a number of sphygmus or the highest and lowest blood pressure on the basis of measured data. In the device, it is judged if an electrocardiographic wave signal generated from an electrocardiographic wave detecting circuit and the sphygmus signal generated from a sphygmus detecting circuit have been output in a corresponding manner to each other. If not, or if one of the above signals has not been detected, either the gain of the electrocardiographic wave detecting circuit or the gain of the sphygmus detecting circuit is increased so as to allow a precise detection of the signal.
