SAT FAC numbers

[John Ross]

Hi,
I tried your FAC #'s and I don't get your results.
Are you sure you are stopping the lights with the SAT set to F5, then
changing the octave to F6, and stopping the lights with the cents button?
Stop the lights on A5, change octave  to A6, then use cents button. On the
C6, stop then change to C7, and stop with the cents button.
When you set the SAT to A4, it is actually reading A6, this is where your
didcrepancy is coming in. I think if you tune it and check it with the SAT
on page 0, and A4,it would show you the lights as being still.
I get A0  -11.2   and C8  +21.4, using your #'s.
