Reference Pitch Adjustment
The A4 reference pitch may be set to any frequency between 220.0 Hz and 880.0 Hz in .1 Hz increments. (Default is 440.0 Hz).
The frequency of the note in Hertz can be displayed along with the note name and octave.
Uses standard 9 Volt battery (included) or optional AC adapter (9 Volt DC).
The Turbo Tuner remembers the settings from the last time it was powered down. This can be changed by the user so the tuner can power up in any state desired.
The ST-122 uses the equal temperament by default, and the user may define up to 14 different 12 note temperaments. The Just and Pythagorean temperaments are already programmed into the unit at the factory.
A message is shown on the LCD when there is about 1 hour of battery life remaining.
The internal time base of each ST-122 Turbo Tuner is calibrated at the factory to +/- 1ppm (that's .0017 cents) and is guaranteed to maintain an accuracy of +/- .02 cents for the life of the product.
Extends battery life by automatically shutting down when not in use. This feature may be turned off by the user for continuous operation.
