Range: Specify the input range to be used for this channel. Select the range so
that anticipated input signal fluctuations will not exceed this Full Scale
range. If the input exceeds the selected range, an over-range value will be
logged.
AC Noise Reject: Enables software filtering of 50Hz or 60Hz noise on inputs. See
Appendix for an explanation of the 50/60 Hz filtering technique.
Filtering: First order noise filtering can be enabled during channel reading. First
order filtering reduces high frequency noise that may be picked up by
sensor wiring with the cost that it slows down the rate at which a channel
can be sampled. See Appendix for discussion on use of filtering.
