Gear reduction ratio (GR):
The reduction ratio establishes that number must appear on the counter after making a full turn (360°). For example, by choosing a reduction ratio of 15, after one revolution on the window you will see the 015 number. The position of the decimal will help demultiplex the measure, because choosing one decimal place, the 015 becomes 01,5.

Mounting / reading position (PL):
The numerator block can be applied in four different positions. Please choose the most suitable for your application:
P1 = Vertical with numbers on upper part,
P2 = Vertical with numbers on vertical,
P3 = horizontal with numbers in inclined wall,
P4 = horizontal with numbers in vertical wall.

Rotation direction (SR):
O = increase of values with clockwise rotation.
A = increase of values with counter clockwise rotation.
