Filter Count
Filter count defines the number of samples to be averaged per
reading. More samples offer low noise but a longer delay
between measurements. Less samples offer high noise but a
shorter delay between measurements.
Range: 2 ~ 320
Filter Window
The 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.
