If you are dialing in a 30 cent offset, and then measuring the FAC numbers (to lower the overall pitch or raise it), be sure to turn off the SAT, remembering which page you were on. When you return to the page to do your tuning, you won't see any offset in the left window (+ or -). If you see the offset in the window, it will ADD (subtract) the amount to the already corrected FAC tuning. I have a SAT 1 also, and have occasionally forgotten to do this, with resulting sharp tuning and broken strings. The later versions of the SAT do this automatically. I hope this helps. Paul McCloud
