When the Accu-Tuner was first manufactured there was a choice in the method of referencing
notes on a piano. Al Sanderson decided to work with the first A on the piano would be A 0, the
first C would be C 1 and work up the keyboard by octaves. Another method to denote the note
you are tuning was to call the first note on the piano A1, second note as A#2, B 3, C4, C#5 all the
way up to C 88. The Accu-Tuner will go all the way up to B 111.

“A “ MULTIPLIER DEFINITION
If you have found that you enjoy using the Jim Coleman method of measuring the A Stretch
number, then it is possible to set the Accu-Tuner IV to multiply the A4 stretch number at eighty
percent as a default. Once the directions below are followed the Accu-Tuner IV will always
multiply the A 4 measurement by eighty percent (until reset to 1.0), so please set this default with
caution.
1)
Turn on Accu-Tuner, hold down the SHIFT button till MENU appears
2)
Press the NOTE up button three times, display showing: “A Multiplier Def”
3)
Press the SHIFT button, display showing: “A Multiplier Def” and 1.0 when first selected.
4)
To change, press NOTE down till display is showing “0.8”
5)
To store the change press the SHIFT button
To return the Accu-Tuner to the original method for measuring the A4 stretch number, follow the
above directions except in step 4 press NOTE up button until 1.0 is displayed, then press the
SHIFT button.
TEMPERAMENTS
Previously with the Accu-Tuner III, the PAGE button would used to go above the regular pages of
memory until you reached the temperament page 1-7t, or 8-14t then select the correct octave to
enter the non-equal temperament offsets. With the Accu-Tuner IV there is a more direct method
to enter the temperament-offset numbers.
1) Turn on the Accu-Tuner IV
4)
Hold down the SHIFT button till the display shows MENU
5)
Step up with the NOTE button until the display shows Temperaments
6)
Press the SHIFT button and TEMPT 1 temperament will be in the displayed.
If you would like to change the first temperament offsets, press the SHIFT button and the display
will show TEMPT 1 in the lower half of the display, the note to enter the temperament offset for
and display the present cents offset. Once the correct cents offset for the temperament is
displayed, press the SHIFT button to store the desired cents offset. The next note is displayed
after pressing the SHIFT button, now use the CENTS button to change the cents offset. While in
the desired TEMPERAMENT the NOTE up and NOTE down buttons work to review the stored
information. If upon checking there is an error in the offset, just use the CENTS buttons to correct
the error and press the SHIFT button to store the correct offset.
AUTO STEPPING ADJUSTMENT
The Accu-Tuner IV auto stepping is much quicker to step up then the Accu-Tuner III. Some
technicians have loved the new speed; other technicians preferred a little slower auto stepping
speed. Now the choice is up to you, with this menu choice the stepping delay is adjustable from
one to ten. Setting one is the standard setting when the Accu-Tuner IV is delivered from the
factory and you can adjust the delay to ten which will slow the stepping way down. If you find
the stepping quicker than you prefer, try setting this function up to five (follow the procedure
below) , try out the new delay on a piano and decide whether to increase or reduce the delay to
your preference.
