For information regarding the damping function when the input change is greater than
0.2 percent of the sensor limits, refer to
Figure 2-15: Change in Input vs. Change in Output with Damping Set to Five Seconds
Damping can be applied to a number of parameters in the Rosemount 644 Transmitter.
Variables that can be damped are:
• Primary Variable (PV)
• Sensor 1
• Sensor 2
• Differential temperature
• Average temperature
• First good temperature
Note
The instructions below only refer to the damping of the Primary Variable (PV).
Set damping value using Field Communicator
From the HOME screen, enter the Fast Key sequence.
Device Dashboard Fast Keys
Set damping value using AMS Device Manager
Procedure
1. Right click on the device and select Configure.
2. In the left navigation pane select Manual Setup.
3. On the Sensor 1 Tab find the Setup group box.
4. Change the Damping Value to the desired setting.
