Figure 2-10: Analog Zero and Span Buttons
A. Zero and span buttons
Note
• If the transmitter security is on, adjustments to the zero and span will not be able to be
made. 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 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
outputs the 25 inH
2.6.4 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.
