I used a tone generator with a test program that changed the frequency in
0.1 cent (a cent is 1/100th of a semitone) steps. I took the data for D4,
which is approximately 293.66Hz and corresponds to the first string of a
dobro in G tuning.
On the Intellitouch you lose bars on the right as you go flat, or on the
left as you go sharp. At D4 +3.3 cents I lost a bar on the right (this is,
all but one bar were still showing). At D4 -1.9 cents I lost a bar on the
left. Between those two readings all bars were showing.
A few things about using electronic tuners:
1) The fundamental frequency of a plucked string varies in pitch by roughly
3 cents, being sharpest when the string is first plucked and going flatter
as the amplitude of the vibration dies down.
2) For standard digital displays (not counting virtual strobes) tuners are
generally programmed to indicate "in tune" within a window that is roughly
+/- 4 cents. This is done to give a stable display while the string changes
in pitch as described above.
3) Analog displays do not need to be buffered in this way and can be read to
a fraction of a cent.
I like Rob Ickes method of tuning: tune the third string to a reference, and
tune the rest to the third by ear.
