smooth variations in output readings caused by rapid input changes.
Determine the appropriate
stability, and other requirements of the loop dynamics within your system. The Damping
command uses floating point configuration, allowing you to input any damping value
within 0 - 60 seconds.

• To change the zero (4 mA/1 V point) while maintaining the span: press and hold
Zero button for at least two seconds and then release.
• To change the span (20 mA/5 V point) while maintaining the zero point: press
and hold the Span button for at least two seconds and then release.
Note
4 mA and 20 mA points must maintain the minimum span.
Note
• If the transmitter security is on, you will not be able to adjust the zero or span
points.
• 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 measure and report all readings
within the digital limits of the sensor. For example, if the 4 and 20 mA (1–5
Vdc) points are set to 0 and 10 inH
25 inH O, it digitally outputs the 25 inH
