Re: 3 x 12 Schmidt & Bender
From Schmidt Bender web site.
Remove the turret caps. The elevation dial will be marked with either a "U" or "H" for up and a "D" or "T" for down. The windage dial is marked with an "L" for left and an "R" for right. Turn the dial in the direction you want to move your shot. For example, to move your shot down and to the right, turn the elevation dial clockwise in the direction of "D" or "T." Then move the windage dial clockwise toward the "R."
