The frequency 440.00 Hertz are to be raised by 5 cent:
440.00 Hz * 1200/5 2 = 441.27 Hz
The frequency 440.00 Hertz are to be raised by 100 cent, which means by one semitone:
440.00 Hz * 1200/100 2 = 440.00 Hz * 12 2 = 466.16 Hz
The frequency 466,16 Hertz are to be lowered by 100 cent, which means by one semitone:
466.16 Hz : 1200/100 2 = 466.16 Hz : 12 2 = 440.00 Hz
5.3 The target frequency of the Tuning Set
The microprocessor installed in the Tuning Set creates the target frequency as shown in the fol-
lowing equation:
Wherein:
f. Target frequency
n c c: Cent adjustment
o + + n: Tone number (a = 0, b = 1...gis = 11)
k 12 1200 k: Concert pitch setting (220 Hz... 880 Hz)
f = * 2 o: Octave (1 = A-2(27,5 Hz)...9= a-5(7040 Hz)

5.4 Cent adjustment of historical temperaments
Please refer to the information as listed in the attached tabloid.
5.5 Cent reference function
All temperament tables pre-programmed in the tuning device are conceived to the effect that for
the tone “a” the cent deviation equals zero. The cent reference therefore is "a". In some cases it is
recommendable to adapt this cent reference to a tone other than “a”. If a different tone is defined
as cent reference for the tuning device, the cent values in the temperament tables are also raised
or lowered by the same amount for each tone, with the result that the cent reference for that par-
ticular tone equals zero.
Example: cent deviations of the "Kirnberger III" temperament with the cent reference setting = "a"
(standard case):
a b h c c# d d# e f f# g g#
0 +6,5 -1,5 +10,5 +0,5 +3,5 +4,5 -3,5 +8,5 +0,5 +7,0 +2,5
For the cent reference setting = "c" 10,5 cent are subtracted from all above amounts:
a b h c c# d d# e f f# g g#
-10,5 -4,0 -12,0 0 -10,0 -7,0 -6,0 -14,0 -2,0 -10,0 -3,5 -8,0
