ABSTRACT:
Process variable transmitters, and method for calibrating such device, are disclosed that support calibrating, within a single transmitter device, multiple operating ranges such that a transmitter can switch from a first calibration correction definition associated with a first calibrated range, to a second calibration correction definition associated with a second calibrated range without having to perform a calibration procedure. Thus, rather than supporting only a single calibration definition, a calibration memory for the process variable transmitter comprises multiple calibration correction definition entries. Each calibration correction definition entry potentially expresses a correction relationship for one of multiple calibrated ranges represented in the calibration memory.
