The adjustment in the EZABL Mini has a metal stop tab that prevents from overshooting the adjustment. If you are not careful and/or you use a screwdriver too larger (or too small) you can strip out the adjustment.
Use a #2-#2.5 size screwdriver to adjust this adjustment and GO SLOW. The adjustment on the mini is more sensitive than the full size if you are used to adjusting that sensor.
