Automated Calibration of Blood Pressure Signal Conditioners

A system for automatic calibration of blood pressure transducers is described. Automatic calibration is accomplished by activation of an analog-controlled servo system that sets the zero balance and gain in a single sequence. An unlimited number of transducers may be calibrated simultaneously, and calibration is completed within a period of less than 1 min. Accuracy and repeatability are assured without dependence on the operator's judgment.
