a. Connect an external microphone to the EXTERNAL 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 above. If necessary, raise or lower the standard
tuning reference pitch of the tuner (Concert A setting under the SETUP menu).
c. You are now ready to begin. For the remainder of this section we will assume that your instrument is tuned in "C"
to a pitch of A = 440 Hz. The normal RUN screen of the tuner will be displayed:

d. Play your note into the microphone, while your partner watches the strobe window. While you are sounding your
note, your partner will press the UP ARROW and/or DOWN ARROW buttons until the dark markings on the tuning
wheel 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 at the "+" (sharp) or "-" (flat)
"xx.x ¢" (cents) location of the display screen.
f.
Musical tuning is measured by a unit 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 Model 590
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) at the selected temperament and scale note.
7. USING THE PETERSON AutoStrobe 590 AS A METRONOME
The Model 590, when not needed as a tuning instrument, can function as a fully programmable audio/visual metronome.
There are two methods to initiate its use. The bottom line of the LCD screen ALWAYS indicates the current functions (if
any) of the four Function buttons (labeled "1" through "4") directly beneath. When the normal RUN screen (shown below
at the left) is active, button "4" is labeled "MET" for metronome. Pressing this button once, will cause the Model 590 to
cease operating as a strobe tuner and prepare for metronome operation by a) replacing the RUN LCD screen with the
METRONOME screen, and b) spinning the strobe motor at a new unchanging speed which is explained below.
