Note
If the transmitter security is on, adjustments to the zero and span will not be able to be made. Refer to

"Configuring transmitter security" on page 36
The span is maintained when the 4 mA/1 V point is set. The span changes when the 20mA 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 measure and report 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
transmitter detects a pressure of 25 inH
range reading.

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 the
user to input any damping value within 0.0–60.0 seconds.
