The specification of the cutoff frequency has a decisive significance for the
suppression of interference. With the specification of the cutoff frequency, the
"quickness" of the reaction of the scale to the change of the measured value is
determined.
For example, a value of 5 Hz leads to a relatively rapid reaction of the scale to
a change in weight; a value of 0.5 Hz makes the scale more "sluggish".
The mean value filter is used to calm the weight value when there is incidental
interference. The weight value is formed afresh every 20 ms from the last
30 weight values.
