To use the strobe tuner, select the desired note and observe the pattern created when playing. Rotation indicates that the note is sharp (clockwise) or flat (anticlockwise). The faster the rotation, the more out-of-tune. This rotation is very precise and gives a much more accurate result when compared to ordinary electronic tuners. Each ring on the disc corresponds to a partial above the fundamental (the two inner rings are below the fundamental) and can be used to tune instruments with many partials.
* Note and octave selection
* A4 = 440Hz (adjustable in fractions of a Hz)
* Mask aperture size (to adjust the pattern clarity)
* Noise threshold (to block out background noise)
* Frequency Calibration (adjusts in 0.1c increments to a specific device or instrument)
* Auto-detect note
This strobe tuner is not like some others around that "emulate" a "strobe display". This tuner has an internal model of virtual wheels and flash lamps that actually perform the same process that a real strobe tuner would do.
