NOTE: The automatic note detection feature is based on reference tuning of A=440 Hz and Global Cent Offset (which
appears on the second line of the RUN screen) set to 0 cents. Any deviation from these tuning references will limit proper
note sensing to less than the usual ±50 cents range. For most applications, deviations in the range of A430 to A450 or,
separately, up to about ±40 cents Global Cent Offset will yield reasonable results for automatic note selection. Of course,
there are no limitations over the full range of offsets available in the tuner when using MANual note selection.
HINT: When tuning a stringed instrument like a guitar or bass, image clarity and automatic note selection are usually
improved by plucking away from the bridge with a fingertip (as opposed to a fingernail or pick) using medium force. This
minimizes the harmonic (overtone) content of the tone while maximizing the fundamental frequency that is to be tuned.
