Damping The Damping command changes the response time of the transmitter to
smooth variations in output readings caused by rapid changes in input.
Determine the appropriate damping setting based on the necessary response
time, signal stability, and other requirements of the loop dynamics of your
system. The default damping value is 0.50 seconds and can be reset in fixed
increments of 0.05, 0.10, 0.20, 0.40, 0.80, 1.60, 3.20, 6.40, 12.8, or 25.6
seconds.
Field Communicator
LCD DISPLAY The LCD display connects directly to the interface board which maintains
direct access to the signal terminals. The display indicates output and
abbreviated diagnostic messages. A display cover is provided to
accommodate the display.
For 4-20 mA HART output, the LCD display features a two-line display. The
first line of five characters displays the actual measured value. The second
line of six characters displays the engineering units. The LCD can also display
diagnostic messages. Refer to Figure 3-6.
For 1-5 Vdc HART Low Power output, the LCD display features a single-line
display with four characters that display the actual value. The LCD can also
display diagnostic messages. Refer to Figure 3-6.
