5.4 Filter setting [ FILTER ]
In various applications, brief pressure surges or other undesirable short signal fluctuations
may occur. For this case, the PUC 28 has a low-pass filter for smoothing the measured values
(see Fig. 14). The filter time, which can be set, is dependent on the expected signal
fluctuations and the desired degree of smoothing.
