The operating range for a process variable transmitter used as a pressure transmitter is selectively non-interactively adjusted by successively applying upper and lower range values (URV and LRV) of input pressure to produce an LRV output signal and calculating the URV and the Span which is equal to the difference between the upper and lower range values, i.e., URV-LRV, to produce outputs from the transmitter representing the new upper and lower range values corresponding to the calculated Span.
