Adjustment of filter mode
(do.26, do.27)
To optimally adjust the filter to interference sources, different modes can be selected
with do.26 or do.27:
Value Function of do.26 / do.27
0
The filter output changes only if during the entire filter time (do.28/do.29) a
constant signal was applied to the filter input.
1
An average is formed over the adjusted filter time (do.28/do.29)
2
The filter output is set if during the entire filter time (do.28/do.29) a constant
signal was applied to the filter input. The filter output is immediately reset as
soon as the input signal is no longer available.
