Note
• If the transmitter security is on, you cannot make adjustments to the zero and span.
Refer to
• The span is maintained when the 4 mA/1 V point is set. The span changes when the 20
mA/5 V point is set. If the lower range point is set to a value that causes the upper
range point to exceed the sensor limit, the upper range point is automatically set to the
sensor limit, and the span is adjusted accordingly.
• Regardless of the range points, the transmitter measures and reports all readings
within the digital limits of the sensor. For example, if the 4 and 20 mA points are set to
0 and 10 inH
the 25 inH
2.8.3 Damping
The damping command changes the response time of the transmitter; higher values can
smooth variations in output readings caused by rapid input changes.
Determine the appropriate damping setting based on the necessary response time, signal
stability, and other requirements of the loop dynamics within your system. The damping
command utilizes floating point configuration, allowing you to input any damping value
within 0.0–60.0 seconds.
Damping with a Field Communicator
Procedure
1. From the HOME screen, enter the Fast Key sequence.
2. Enter desired damping value and select APPLY.
Damping with AMS Device Manager
Procedure
1. Right click the device and select Configure.
2. Select Manual Setup.
3. Within the Pressure Setup box, enter desired damping value and click Send.
4. Carefully read the warning and click Yes if it is safe to apply the changes.
