Primary Variables
Follow the prompts on the Field Communicator to view or edit Primary Variable information.
D PV is— Display the PV currently stored in the instrument.
Change PV— Follow the prompts to change the PV. Select Level Units if the PV is level, Interface Units if the PV is
Interface, or Density Units if the PV is Density.
D PV Units— Permits changing the PV units.
For density measurement:
g/cm
3
—grams per cubic centimeter
kg/m
3
—kilograms per cubic meter
lb/gal—pounds per gallon
lb/ft
3
—pounds per cubic foot
g/mL—grams per milliliter
kg/L—kilograms per liter
g/L—grams per liter
lb/in
3
—pounds per cubic inch
SGU—specific gravity units
For level and interface measurement:
ft—feet
m—meters
in—inches
cm—centimeters
mm—millimeters
D Level Offset— Displays the current Level Offset stored in the instrument.
Set Level Offset— Adding a level offset permits the process variable engineering units to correspond to the externally
measured level or interface (see figure 4‐3). Follow the prompts on the Field Communicator to enter the offset value. If
you set the level offset after you have set the range values, be sure to verify that the range values are still correct.
