Operation and Maintenance

4.4.2 Configuring fixed process variables

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 clicking 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.

4.5 Process variables

4.5.1 Process variable tabs

The Process Variables screen shows a graphical representation of the respective variable. An

example of the Primary Variable tab is shown in Figure 4-7. The chart on these Process Variables

tabs will begin plotting when the user first navigates to the screen, and will only continue

plotting while the user is viewing this tab. The user may view a larger version of the chart by

clicking on the Large Chart button.

Each of the four digital output variables has a screen similar to the one shown in Figure 4-7.
