Description of Device Parameters Deltabar FMD71, FMD72
84 Endress+Hauser
Display • Off
The output signal is not damped.
• On
The output signal is damped. The attenuation constant is specified in the "Damping"
(017) (184) parameter
Factory setting On
Damping (017)/(184)
Navigation Setup → Damping (017)/(184)
Write permission Operators/Service engineers/Expert
(if the "Damping" DIP switch is set to "on")
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
