Abstract
This invention, which comprises a cuff, an exhaust portion, a pressure sensor, an A/D converter, a microcomputer, a display, and an operation portion, initially determines the maximum pulse wave amplitude by comparing the size of each pulse wave, and it then determines the maximum pulse wave amplitude by comparing the sizes of the values obtained by totalling each pulse wave amplitude along with its preceding and subsequent pulse wave amplitudes, and it finally determines the maximum pulse wave amplitude by evaluating whether the different value between each preceding and each subsequent pulse wave amplitudes which occur after the maximum pulse wave amplitude has a negative(-) sign, thereby eliminating erroneous calculations caused by oscillation noise interference.
