Abstract
An electronic pressure instrument that is easy to monitor and calibrate, and is relatively small and functional, is disclosed. The electronic pressure instrument includes two pressure inputs for receiving two fluids, which can eventually be provided to a transducer for converting a pressure differential of the two fluids to an electrical signal. Positioned between the two pressure inputs and the transducer is a rotatable valve having a mechanical test port and a plurality of conduits for selectively directing at least one of the fluids to the transducer or the mechanical test port. When the valve is in a first position, the two fluids are directed to the transducer. When the valve is in a second position, the at least one fluid is directed to the mechanical test port.
