D PV, SV or TV display the PV, SV, or TV assignment, as selected, currently stored in the instrument.
D Units— Permits changing the 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
For TV and SV the units are read-only, as they are controlled by the Temperature Units selection in the Sensor Units
menu.
D Damping changes the response time of the controller to smooth variations in output readings caused by rapid
changes in input. Determine the appropriate damping setting based on the necessary response time, signal
stability, and other requirements of the loop dynamics of your system. The default damping value is 0.2 seconds.
and can be reset to any value between 0 and 16 seconds in 0.1 second increments. When set to 0, the damping
function is off. Damping for SV and TV is fixed at 60 seconds and is displayed for information only.
Net instrument response is a combination of analog input filtering, sensor damping, PV damping, and output
filtering.
Change PV
Allow you to change the PV assignment. Select Level Units if the PV is level, Interface Units if the PV is Interface, or
Density Units if the PV is Density.
Note
If the PV assignment is changing to Level or Interface, go to the Process Fluid(s) menu and edit the configuration data for fluid
density before returning the loop to Auto.
