Description
Enter damping time (time constant t) ("Damping" DIP switch set to "on")
Display damping time (time constant t) ("Damping" DIP switch set to "off").
The damping affects the speed at which the measured value reacts to changes in pressure.
Input range 0.0 to 999.0 s
Factory setting 2.0 sec. or according to order specifications
Level before lin. (019)
Navigation Expert → Measurement → Level → Level Before Lin. (019)
Write permission No write permissions. Parameter is read only.
Description Displays the level value prior to linearization.
Meas.Diff.Press. (020)
Navigation Expert → Measurement → Pressure → Meas.Diff.Press. (020)
Write permission No write permissions. Parameter is read only.
Description Displays the measured differential pressure after sensor trim, position adjustment and
damping.
