Damping Adjust the damping time constant for Process Temperature (PV3) to
reduce the output noise. We suggest that you set the damping to the
smallest value that is reasonable for the process.
The damping values (in seconds) for PV3 are:
0.00d, 0.3, 0.7, 1.5, 3.1, 6.3,
12.7, 25.5, 51.1, 102.3
d Factory setting.
Background The electrical noise effect on the output signal is partially related to the
turndown ratio of the transmitter. As the turndown ratio increases, the
peak-to-peak noise on the output signal increases. See the Damping
paragraphs in subsection 6.6 for a formula to find the turndown ratio using
the pressure range information for your transmitter.
