Abstract
A device for testing the operability of a blood pressure monitor. The device includes a signal generator for generating a plurality of different output signals simulating a variety of static blood pressure levels. A plurality of display devices are included, each device corresponding to one of the given static blood pressure levels. Control circuitry coupled to a single push button switch simultaneously selects a different blood pressure level to be generated and energizes its corresponding display device upon each sequential activation of the switch.
