Filter count
Filter count defines the number of samples to be
averaged per reading. More samples offer low noise but
a long delay. Less samples offer high noise but a short
delay.
Range
2 ~ 100
Filter window
Filter window defines the threshold for when the digital
filter data is updated again. When the AD data falls in the
range between TH and TL, the filter keeps processing.
When the AD data falls out of the range between TH
and TL, the filter will restart. When measuring unstable
signals, appropriately setting the filter window can
improve the measurement speed.
