4.4.2 Configuring fixed process variables
Mass and energy flow Fast Keys
Direct process variable output Fast Keys
Under the Fixed Process Variables heading, the user may temporarily set the differential
pressure, static pressure or process temperature to a user defined fixed value for testing
purposes. Once the user leaves the Configure Fixed Variable method, the fixed process
variable will be automatically returned to a live process variable measurement.
4.4.3 Analog output loop test

Under the Analog Output Verify heading, a Loop Test can be performed by selecting the
Loop Test button. The loop test command verifies the output of the transmitter, the
integrity of the loop, and the operations of any recorders or similar devices installed in the
loop.
