PV Damping
PV 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.
Net instrument response is a combination of analog input filtering and output filtering.

D Upper Fluid Density— Indicates the density of the upper fluid.
Note
Upper Fluid Density is only visible if PV is Interface.
D Lower Fluid Density— Indicates the density of the lower fluid.

Upper Density Table (only visible if PV is Interface)
Lower Density Table
Two specific gravity tables are available in the instrument to provide specific gravity correction for temperature. For
level measurement applications, only the lower specific gravity table is used. For interface applications, both the upper
and lower table can be displayed and edited. For density applications, no specific gravity correction table is presented.
Example entries for saturated water are given in table 4‐2. Figure 4‐4 shows the curve that results when these values
are plotted.
