the piano. To return the tuner to standard A = 440Hz, simply move the
power switch to OFF and then back ON. The tuner always resets its
internal scale to A = 440Hz when it is turned on.
Manual Calibration
Most other tuners on the market allow the user to manually calibrate to a
very limited number of pitches. However, the can be calibrated to any of
12 precise pitches. This feature will be especially useful for tuning in-
struments that use open tunings, such as banjos, dulcimers, Irish harps,
pedal-steel and bottleneck guitars, etc., or any time you may wish to
tune to a “natural scale” rather than an “even-tempered scale.”
Example: If you wish to calibrate the tuner from standard A = 440Hz to
A = 438Hz, press the FUNCTION button and hold until the top row of
LEDs (MANUAL/FLAT, TONE OUT/IN TUNE and TRANSPOSE/SHARP)
light in sequence. Release the FUNCTION button when only the
(MANUAL) LED is lit. The bottom row of LEDs will begin to light in se-
quence. (Each LED represents 1 Hertz.) Press the FUNCTION button
when the LED corresponding to 438Hz lights. The tuner’s scale is now
shifted flat from A = 440Hz to A = 438Hz. Please note the manual cali-
bration scale is referenced in Hertz and in ¢. NOTE: there are 100¢
between any two adjacent notes in the musical scale, and one Hertz is
equal to one vibration per second. To return the tuner to standard A =
440Hz, simply turn the power switch to OFF and then back ON.
Tone Generator
The STX1100 will generate any reference tone over a two-octave range
so that you may tune by ear.
