Query: First guitar tuner

This is the first guitar tuner i have bought so i dont know what to expect. I don't play guitar, but bought it for my son, along with a guitar and amp. So i attempted to tune the guitar myself before i gave it to him, and it was so easy. just remember to turn up the volume on the guitar first, cause i didn't at first and it wouldn't work.
