Good news for happy SAT users:

A Simple Way of Using the SAT III (3 
steps)                                Jim Coleman, Sr.

It is possible to measure just one note with the SAT III and begin tuning 
immediately. The older style F4 Stretch mode can be used in conjunction 
with the Double Octave Beat control to tailor a tuning to your personal 
preference. Here is how to do it:

1.  After turning on SAT, select note F and octave 5, play the note F4 
and tune to            stop LEDs.
2.  Change Octave to 6 and stop LEDs with the MSR and Cents buttons.
3.  Hold down SHIFT and touch STO Stretch. Touch STRETCH button again. 
This            takes you out of TUNE mode and puts you in F4 STRETCH 
mode. This is all
         you have to do to begin tuning immediately on any piano.

IF YOU HAVE PERSONAL PREFERENCES CONTINUE AS BELOW

4.  Select and TUNE A4 to stop LEDs. Change note to A3 on SAT. If while 
playing             A4, the LEDs are moving clockwise more than  
revolution per second, use            negative DOB to shrink the stretch 
by .1 or .2 beats per second.  ** Change            note up and down to 
apply the DOB. Sometimes you need positive DOB.
5.  Tune A3 to this setting. If you like it, tune the rest of the notes 
from A4 down             to C3, listening to the Major 3rds and 5ths as 
they become available. If the            3rds slow down too quickly for 
you where the tenor bridge turns hockey-stick          like, you will 
need to gradually  erase some of the negative DOB and possibly          
add some positive DOB gradually until you get to the highest wound 
strings.           At that point, it is usually necessary to erase any 
positive DOB to keep the              M3rds in line, where the lower note 
of the M3rd is a wound string.
6.  TUNE from A4 to F6. Usually this part of the scale will work very 
well without               any alteration. The F4 Stretch program will 
maintain octaves at about  to             beat stretch throughout this 
area. 

Some tuners prefer to tune the High Treble and Bass by ear. If you prefer 
some guidance in these areas for consistency sake, you can use the 
following additional procedures.

7.  After everything from C3 to F6 is tuned (the limit of the F4 style 
Stretch                       tuning), you can continue by pressing the 
TUNE button to get into Tune                 mode and continue on up to 
C8.
8.  Select F#6, Play F#4, stop the LEDs and TUNE F#6 to this setting. Do 
a similar           thing for each note such as G6, G#6, A6, etc. to C8, 
tuning to a setting of               the 4th partial of the note two 
octaves lower.
9.  For tuning the Bass from B2 on down to A0, set the SAT III in Tune 
Mode, note           F#5. Play the already tuned B3 and stop the LEDs 
with the cents buttons.               TUNE B2 to this setting.
10. Continue down with setting F5, playing A#3, stopping LEDs, and tuning 
A#2,              etc., down to tuning A0 with the SAT set on E3 in TUNE 
mode..

IF YOU WOULD LIKE TO AVOID MEASURING EACH INDIVIDUAL RELATIONSHIP IN THE 
TREBLE, USE THE FOLLOWING PROCEDURE. (Credits to Joe Goss for this)

11. Prepare 11 pages of memory where you have used values for the A4 of 
the FAC                    facility which varied in .5 cents increments 
starting from  A4 stretch = 5.0 to                       A4 stretch = 
10.0.
12. Now when you reach the extent of the F4 type Stretch tuning at the 
note F6, you can             select one of these pages which has a 
similar value at the note F6. Then continue
           tuning to the top of the piano using this memory tuning. You 
may also use the                   DOB control if you notice more or less 
stretch is required in the high treble for this
           for this particular piano. A similar thing can be done in 
tuning below C3 in the                   Bass

I made a chart like this for my own personal reference:

Comparisons of FAC mode and F4 STRETCH mode.

default values of FAC are: F3=8.0, A4=7.0 and C6=6.0

Page         A4 value:  Resultant F6 offset
50		5.0		4.8
51		5.5		5.2
52		6.0		5.8
53		6.5		6.3
54		7.0		6.7
55		7.5		7.2
56		8.0		7.6
57		8.5		8.1
58		9.0		8.6
59		9.5		9.0
60		10		9.4

At Reno I will be showing some other neat stuff in my class on Sanderson 
Accutuners.

Thanks for listening.
