Any guitar players help me

Hey guys. I have a 12 string semi acoustic washburn guitar. I have also bought an electric tuner. My only problem is I am not sure if I bought the right one. Do I need a special tuner for a 12 string guitar? On the box it says it only tunes basses with 6 string and guitars with up to 7, I didn’t notice this until I got home. Do I need a chromatic tuner? Or can I do it with the tuner I have. It is a KORG tuner.
