6. CHECKING INTONATION WITH THE SC-5000
When you desire to check your playing intonation, the tuner can assist in a very simple manner. You will need a partner
to adjust the pitch of the tuner to match the intonation of the note(s) you are checking.
When checking and adjusting your own intonation, it is useful to use an external microphone. Turn your back to the
tuner while playing your note so you don't see the indications on the tuning discs while your partner is making the
adjustments. That way you will be less likely to slowly change your intonation at the same time your partner is
adjusting the tuner.
a. Connect an external microphone to the Input connector of the tuner. Set this microphone on a stand so that you
can face away from the tuner.
b. Adjust the tuner to the tuning key of your instrument as detailed in Section 4 above. If necessary, raise or lower
the standard tuning pitch of the tuner by following Section 3.
c. You are now ready to begin. For the remainder of this section we will assume that your instrument is tuned in "C"
with a Concert A reference pitch of A = 440 Hertz. The normal Run Mode screen of the tuner will be displayed:
KEY = C
A = 440 xx ¢

d. Play your note into the microphone, while your partner watches the strobe windows. While you are sounding your
note, your partner will press the PITCH UP and/or PITCH DOWN buttons until the dark markings on the tuning
wheel corresponding to your note appear to be stationary. When these markings are stationary the tuner is in-tune
with the note you are playing.
e. The display will show the correctness of your intonation by indicating how many cents sharp or flat your partner
adjusted the tuner to match the note as you actually played it. This is presented in the "+" (sharp) or "-" (flat)
"XX.X" "¢" (cents) location of the display screen.
f. Musical tuning is measured by units called cents, representing a 1/100 division of a semitone. There are 1200 cents
in each octave, and exactly 100 cents between each half-step note in equal temperament tuning. The SC-5000 is
adjustable in a range of 1/2 semitone (+50.0 cents sharp to -50.0 cents flat) from being perfectly in tune
(00.0 cents) with the selected temperament and pitch.
7. ENHANCED RESOLUTION OF INTONATION MEASUREMENTS
As you continue to practice your intonation with the SC-5000, you will find that your pitch accuracy continually improves.
As you find yourself playing more and more closely to perfect intonation, you may desire that your partner adjust the tuner
more closely to your pitch. The SC-5000 has tuning accuracy to within 0.1 cent. The tuner may be adjusted to your note
within that same accuracy. The tuner always starts with a displayed resolution of 1 cent. This is shown as "00 ¢". When
operating in the Run Mode, the tuner can be set for enhanced resolution of either 0.5 cents or 0.1 cents. Press and hold the
ENTER key, then press either PITCH UP or PITCH DOWN and the resolution will be changed to 0.5 cents. To further
