"SET NOTE": In this mode the device automatically switches to the tone b'. It is not possible to
enter a cent deviation value for to tone "a". Its cent deviation is always
automatically set to zero. If you try to enter the tone "a", the display "a = CENT
REF" appears for aprox. 1 second. After that the Tuning Set switches to the next
tone. It is an inherent part of the Cent Relationship and Transposition Function
that the reference tone "a" has no cent deviation (See Cent Relationship and
Transposition function in part 3 of the operating instructions).
"SET CENT": The procedure here is the same as for storing a stretching.
ATTENTION !!!
If you store important data into the Tuning Set, we suggest that you write down these values.
Then, in the unlikely event of a problem occurring with the memory, you can restore your old
values after the device has been repaired.
The range of cent deviation is limited to ñ63.5 cent in the memory mode.
2.9 COMBINING INDIVIDUAL MODES
All modes can be combined. For instance, you can enter any standard pitch in mode 2 ("PITCH")
and subsequently test a chosen tone in relation to this in mode 3 ("CENT-MEAS").
The functions Stretching, Temperament and Interval may be combined, even those that you have
stored yourself.
You can use every function with every standard pitch.

For all those who wish to learn more about Tuning Set CST-5 we will discuss the basic facts on
the following pages.
3.1 THE EQUAL TEMPERAMENT
The Equal Temperament is the most frequently used temperament, it is the basic tuning of CTS-5.
The following example shows its mathematical theory.
Given that standard pitch a' is 440.0 Hertz, then oscillations of the chromatic semi-tone steps are
calculated as follows:
bb' = 440.00 Hz * 12 2 = 466.16 Hz 12 2 = 1.0594631
b' = 466.16 Hz * 12 2 = 493.88 Hz
etc.
When the standard pitch a' is 442.00 Hertz:
