Rod,
I was reviewing the dc conditioners for the load cells and I noticed that
the excitations are not all the same, they are as follows:
1  =>   10.0 v          2  =>   7.001953 v
3  =>   10.0 v          4  =>   7.001953 v
5  =>   10.0 v          6  =>   7.001953 v
7  =>   7.001953 v      8  =>   7.998 v
9  =>   7.001953 v      10 =>   7.001953 v
11 =>     "             12 =>     "
13 =>     "             14 =>     "
15 =>     "             16 =>     "
17 =>     "             18 =>     "

Is this OK or should they all be the same?

Also, there is a filter button in the dc conditioner window, is that for
engaging the antialiasing filter? and if my memory is correct that would
have to be installed on the board for it to work.  I was wondering if
filtering or smoothing the load channels would improve load control because
just sitting still without running a load control file several cylinders
move up and down a little - in response to a little noise on the load
feedbacks.  Is there any other way to filter load feedback at an appropriate
frequency?
