The placement of the ruler has an effect on the shooting result, so it is important
to position the scale correctly. Pay attention to the following points when
placing:
The position where the ruler is placed must be easy to shoot, and the placed
ruler cannot be deformed.
The time for placing the ruler should be after pasting the reflective marker
point and pasting the coded marker point.
