SAT question

[pianolover@worldspy.net]

Here's a question:

 I turn on my SAT II, go to tune 
             mode, (after confirming calibration),and as a test, I strike a49 (on 
             a piano where A4 is tuned EXACTLY to A440. ), and the dots are 
             still,  as they should be.  Then I enter my FAC precisely and correctly, to get my stretch calculations. Then, after 
             I save it to a page, I  go directly back up to play A49...the SAT NOW tells me 
             it's flat, by about 5.5 cents!  Why? I already confirmed it was at A440 
             at the beginning. The manual indicates that the SAT will always show A440
             4-12 cents sharp in FAC mode, which corresponds to 
             calculated pitch of the 4th partial of A4, which is 
             used for tuning...so the dots are spinning backwards. 
             So, now  I must pull it up to stop the dots..at which point A49 is 
             now SHARP!  Am I missing something? I hope you fellow SAT users don't 
             mind explaining this to me, even if it's a dumb question. I just don't get it. 
             Thanks!
