I have two zf4 scopes but have never tried to adjust them. The adjuster on the side is for up or down. and the one on the top is for right to left adjusting correct? There are three small screws located on a small disk on the knob,i believe you remove them to expose the adjusting screw. So what are the small numbers for on the side of the dial?you can turn the knob without removing the small disk and three screws.When does this come into play.I own the book GERMAN SNIPER by SENICH but still need a little help.Thanks So is the other marking there to place or set on 100 meters first and then start the zeroing with the small middle screw located in the up and down adjustment knob? hope i haven't confused anyone
