This is what a concert pitch (standard) tuning for A is
5th string open, just pick it dont put your playing hand on the neck

I advise also learning to tune without the tuner and getting your ear used to roughly how the guitar sounds on each string, then fine tuning it with your electronic friend.
Basic tuning:
Low e @fret 5 = 5th string (A) open
a @fret 5 = 4th string (D) open
d @fret 5= 3rd string (G) open
g @fret 4= 2nd string (B) open
b @fret 5= 1st string Open =E
Ignore the fancy bits on the tuner and just work out how to get the gtr in tune and read the manual later,good luck.
PS -needle straight up is in tune.
