2.3 MEASURING THE STANDARD PITCH OF AN INSTRUMENT
Enter, like in the above example, into the standard pitch program.
For instance a 1 PITCH: 440.0
>2< CENTS: 00.0
Tap the key "A". a 1 PITCH: 440.0
>2A<CENTS: 00.0
AUTOMATIC MODE
When you now strike the tone a1 on your instrument, the standard pitch program of the CTS-5
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 Program Number 3 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 standard
pitch.
NOTE: STANDARD PITCH PROGRAM AND CENT MEASURING PROGRAM.
You may change the actual tone setting in these programs as follows:
Simultaneously and continuously depress keys "E" and "S", and then tap
the keys "<" or ">".
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.
