In certain application the process value is too unstable to be read.
To improve this a programmable low pass filter incorporated in the
controller can be used. This is a first order filter with time constant
specified by

parameter . The default value of FILT is 0.5 sec.

before shipping. Adjust FILT to change the time constant from 0 to
60 seconds. 0 second represents no filter is applied to the input
signal. The filter is characterized by the following diagram.
