Abstract
A computer controlled apparatus for periodically calibrating the electrical outputs of pressure transducers to compensate for circuit-induced errors and produce accurate outputs in real time. Reference signals are periodically input into various circuit elements to determine resultant outputs. The relationship thus determined between these known inputs and corresponding outputs is used to correct the output of the circuit elements during operation.
