2 screws to be exact. One set screw and one adjustment screw. In practice, it's not that easy... at least not the Eagnas because the set screw loosening and tightening will change the setting a few lbs.
I believe there's a third adjustment... I can't remember but since the spring tension is exponential, the spring rate needs to be adjusted too. If incorrect, the dial could be 60 on the mark, however it's off incrementally at 50 & 70 for example.
