Abstract
A pressure transducer arrangement and method of operation is provided. The pressure transducer and methods of operation reduce error in determining an offset value by eliminating error relating to fluid flow through the transducer arrangement when the offset value is determined. In a particular embodiment, the apparatus and method includes a lockout valve that prevents fluid flow between first and second fluid pressure sources when the offset value is determined.
