Rotation direction (y):
0= increase of values with clockwise rotation.
1= increase of values with counter clockwise rotation.
Gear ratio and corresponding scale (zz):
Select the appropriate gear ratio by deciding which number the big black pointer must indicate after the knob has completed one turn. The graduated scale will be proportional to the selected ratio. A ratio of 12 will have a scale that ranges from 0 to 12.

In your orders you must indicate the rotation direction and the desired gear ratio.
Example: On knob D=57 with a hole d1=10, clockwise (y=0) and a ratio of 6 (zz=06) code will be 47006450006.(For ratio 100 zz=00).
