<< Hi Terry:
 
 Keep in mind that the SAT uses various higher partials to tune to over most
 of the keyboard. Only in the  uppermost octave or two does it use the
 fundamental. So when tuning A4 with your SAT and observing the 5.8 cents in
 the display window, the SAT is indicating that the targeted pitch for the
 partial to which it is tuning is at 5.8 cents. You SAT manual will tell you
 exactly which partial it uses for A4. After you tune, turn your SAT off,
 turn it on, press the "tune" button, and see where your A4 is set. It will
 be very very close to 0.0 cents - because here you are measuring the
 fundamental now. If it varies slightly from 0.0, the manual details a simple
 method to offset the SAT to correct for any slight deviation. Do you have a
 manual?

You do not even need to turn the SAT off.  Hit shift-tune, then tune.  Check 
the tuned pitch FAC A-4 to A-4 in the tune mode at zero, and see if the 
lights stop. If the lights do not stop, I am not afraid to tune it at zero, 
then reset the numbers for A-4 in the FAC mode.  After all A-440 is what you 
are attempting to accomplish.
