12 Transmitter operation
12.1 View process and diagnostic variables
Process variables provide information about the state of the process fluid. Diagnostic variables provide data
about device operation. You can use this data to monitor and troubleshoot your process.
12.1.1 View process and diagnostic variables using the display
The display reports the name of the variable (for example, Density), the current value of the variable, and the
associated unit of measure (for example, kg/m
3
).
Prerequisites
For a process or diagnostic variable to be viewed using the display, it must be configured as a display variable.
Procedure
• If Auto Scroll is not enabled, activate ⇩ or ⇧ to move through the list of display variables.
• If Auto Scroll is enabled, wait until the variable is displayed automatically. If you do not want to wait, you
can activate ⇩ or ⇧ to force the display to scroll.
12.1.2 View process variables and other data using ProLink III
Monitor process variables, diagnostic variables, and other data to maintain process quality.
ProLink III automatically displays process variables, diagnostic variables, and other data on the main screen.
Tip
ProLink III allows you to choose the process variables that appear on the main screen. You can also choose
whether to view data in Analog Gauge view or digital view, and you can customize the gauge settings. For
more information, see the Micro Motion ProLink III User Manual.
12.1.3 View process variables and other data using the Field
Communicator

• To view a more complete set of process variables, plus the current state of the outputs, choose Service
Tools > Variables.
• To view diagnostic variables, choose Service Tools > Maintenance > Diagnostic Variables.
