Abstract
A process variable transmitter for use with a removable operator interface has a non-volatile memory and a latching component. The non-volatile memory stores device settings. The latching component prohibits changes to transmitter settings if the removable operator interface is absent. Circuitry in the transmitter detects the presence of the removable operator interface. The removable operator interface can include zero and span settings.
