Hi Jonathon. Some of the _channels are a different representation of the reading
(e.g. different scale - one would be 0-6V range, and one would be 0-21V for
example). Others provide identical readings to the non _channel but have left
those in to keep the channel numbering sane and easy to reference.

No problem regarding the request.
