■ Filter
The analog input is filtered so it reaches approximately 99% of the analog input in the set time. Rapid fluctuations in
the analog input can be reduced by setting the filter, but increasing the filter slows down the tracking of fluctuations
in the analog input. The filter must be set for each channel.
