Pluck one string at a time and let it ring. The tuner detects which string you're playing.

If the needle is left of centre the string is flat, so tighten it. If it's right of centre the string is sharp, so loosen it.

Turn the peg slowly until the note turns green and the needle sits in the middle. Then move on to the next string.

Go round once more: tuning one string slightly changes the tension on the others.
