13.3. Dosing filter setting

In PUE 41 terminals an special averaging filter for dosing process has
been implemented. The result of this filtration, instead of traditional filters
for static weighing, is compared with dosing setpoints. The filter parameter
is the number of samples from the A/D converter (1 to 10). When the filter
is set to 1 every reading from the A/D converter is compared with the
dosing setpoints, which does not introduce any delay. If the filter
parameter is set to n>1, the filtering result will be calculated as
an arithmetic average from the last n measurements.
