6.8 TempConf Configuration - PV3, Continued

Damping

Background

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.

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.
