Tuning Fx crown spring tension wheel 1-24

[benshevlin]

Hey 

Just wondering about the hammer spring tensioning wheel on most fx crowns it says 
Max 
Min 
1-5 or
A-E
But mine says 1-24 and also you cant tell what number you on as there is no arrow pointing to the number. Just wondering can anyone help me out with this.

You have the new improved hammer adjustment wheel, the number at the top (12 o’clock) position is the setting.
