Sometimes it is hard to see things looking down the neck from the headstock, if it is close to flat. Put a capo or fret at the first fret and last fret, you should have around .014 thousandths or a business card thickness between the bottom of the string and top of the 8th fret. This measurement also depends on the radius of the neck. If the relief is more than that, then a truss rod adjustment is needed. I've also just laid a straight edge across the the frets, if you have a backbow the straight will rock on a fret somewhere in the middle. If concave, then there will be a gap. Maybe you have read:

Hopefully all this will make some sense. It is not hard, just need some practice to get comfortable with the procedure.
