The value of the entered filter constant must be between zero and 100. No filtering
occurs with a value of zero and maximum smoothing/filtering (and the slowest read
time) occurs with a filter constant of 10. The graph below illustrates the number of
readings required to reach a new value when the product changes. For example, a filter
value of 10 takes two to three readings to settle out completely, whereas a filter value
of 90 takes as many as forty readings. Multiply the number of readings required to settle
the output by the read time to calculate the amount of time required for settling.
