ABSTRACT:
A method of determining the accuracy of a pressure sensor in a surgical console is disclosed. The method involves actuating a linear actuator so that its plunger is linearly displaced a pre-defined amount, and measuring the force exerted by the plunger on a non-compliant member. The accuracy of the linear actuator and the plunger are determined by comparing the force measured in the measuring step to a pre-defined force.
