Damping- and Smoothing

Damping and smoothing are both filter functions, which are configurable, and have different effects on the way the input signal is processed.  The time constants can have values of 0 to 60 seconds and 0 to 30 seconds respectively.

Damping causes conventional single-pole low-pass filtering which is similar to an R-C network.  Smoothing, which is available only for the temperature converter, causes a more ‹intelligent› damping where small changes (noise) are heavily suppressed and large (tendency) changes are processed normally.

Although high damping values will greatly suppress noise and make the output signal stable, it causes a slow response time. The smoothing function avoids this disadvantage by removing the filtering while there are very large signal changes on the input.

Higher damping values are recommended for slow input signals requiring high levels of stability, while fast signals require lower damping values. If in doubt, some experimentation will yield the best results.
