• Scale Marks
The number of scale marks varies depending on the time corresponding to one cycle.
Scale marks consist of main scale marks and subscale marks. Main scale marks are
used to divide the cycle into sections; subscale marks are used to divide between the
main scale marks. The number of divisions created by main scale marks and subscale
marks are as follows:
Time/rev Number of Divisions
Created by Main Scale
