Turn on the microphone, pick Guitar and pluck the open 6th string. The tool shows the note, the Hz and how many cents you are above or below, and marks each string as in tune once it sits within 5 cents.
The lowest guitar string, at 82.41 Hz.
Same note as the 6th string at fret 5.
Two octaves above the 6th string.
Doubles the frequency: E3 at 164.81 Hz, handy for checking the octave.
Raising A from 440 to 442 Hz raises every note by about 7.9 cents.
For E2 that is a 0.48 Hz window, from 82.17 to 82.65 Hz.
Click Turn on microphone, allow access and pick Guitar. Pluck the open 6th string (the thickest): the tuner shows the note and the cents. If the needle goes left the string is flat and you tighten the tuning peg; if it goes right, you loosen it. Stop when the panel turns green and move on to the next string. When you finish, go back to the first one, because string tension redistributes along the neck.
Start with the 6th (E2) and work up to the 1st. The order matters little for the final result, but starting with the thickest helps: the neck takes most of the tension early, and you only need to recheck the first string at the end.
Yes, any string that produces a clear pitch works. On an electric guitar, keep the amp at low volume with the microphone near the speaker, and avoid heavy distortion, because noise confuses the measurement.
The tuner holds the last reading for half a second and then clears it, because with no sound there is no pitch to measure. Pluck the string again with slightly more force.
