2.3  Measuring the concert pitch of an instrument 

Enter, like in the above example, into the pitch mode. 

 
Display for instance: 

Tap key "A". 

When you now strike the tone a1 on your instrument, 

the standard pitch program of the device starts to adjust 

to the played tone. 
The tone to be measured must be played until the stroboscopic display almost or completely 
comes to a stop (tones of short duration must be stricken repeatedly). Now press the key "A" 
again, preferably while the tone is still heard. This will turn off the automatic mode. 
If necessary, adjust the CTS-5 to the correct tone, by tapping the keys "<" 
or ">", until the stroboscopic display is standing still, while the tone is being played. Only then 
the CTS-5 is adjusted to the correct value. 
You may now read the measured standard pitch on the LC-Display. 

2.4  Measuring a tone's cent deviation 

The unit of measure CENT is used in accoustics for the deviation of a tone from a basic 
frequency. A cent is about one hundredths of a semi-tone step. The exact value is described in 
Part 3 of these Operating Instructions. 
Please use mode number 3 "CENT MEAS" for cent measuring. Its procedure is the same as 
that for measuring the standard pitch. 
The cent-adjustment of the CTS-5 always relates to the previously adjusted tone and concert 
pitch. 
Remark to  "CENT-MEAS" mode: To adjust the note without leaving this mode, operate like this: 

Keep "S" pressed and shortly tap „E“. From now on, you can adjust the note with " < >". 
Tap "E". From now on, you adjust the cents again with "< >" 
 

2.5 Piano tuning 

First things first:  We cannot overemphasize the fact that piano tuning requires experience. If it 
is done without the necessary knowledge and skills, the piano may be irreparably damaged. In 
one tuning, a piano should never be raised or lowered by more than 30 cent. 
When tuning pianos and grand pianos, the stretching of tune has to be considered for various 
reasons, i.e. that in deviation from the standard tune, high tones have to be tuned higher, and 
bass tones lower. We will discuss this further in Part 3 of the Operating Instructions. The Tuning 
Set CTS-5 may be adjusted so that, based on stretching diagrams, which are incorporated in 
the CTS-5 program, these deviations or stretchings are automatically considered. 
Several stretchings are available in the Tuning Set. Four are permanently programmed. The 
stretching number 5 and number 6 you can enter yourself, using program 6 (MEMORY) and 
program 7 (PIANYZER) You may find the diagrams of the four permanently programmed 
stretchings in Part 3 of the operating instructions. 
The choice of the optimal stretching depends on various parameters of the instrument to be 
tuned. Another important consideration is the preference of the musician.
