Turn 1 gear, at this time parameter X=101+1=102 to be regulated, another mistake hour hands rotate 1 gear, at this time parameter X=to be regulated
102-1=101.
When the key on user's push-turn key rotates knob, down state processing step is executed at this time.User
1 gear is rotated clockwise, at this time speed value S=0+1=1, parameter X=100+1*5=105 to be regulated, if user keeps pressing
Lower state rests on the gear, then can treat adjustment parameter X and be continuously adjusted, i.e., parameter X to be regulated is continuously from increasing, every time
From increasing 5.If parameter X to be regulated continuously Zi increasing to 150 when, user rotates clockwise a gear again, at this time speed value S=1+1
=2, parameter X=150+2*5=160 to be regulated, parameter X to be regulated is every time from increasing 10 at this time, after user unclamps key, from increasing
Stop.
