Abstract:
A method and apparatus for verifying operation of process variable transmitters in process control or monitoring systems is provided. A process variable is measured with a process variable transmitter to verify operation of the process variable transmitter by comparing the process variable with a reference. A data entry is placed in a database which indicates operation of the process variable transmitter has been verified.
