DISTANCE (D) : SPOT SIZE (S)
The distance:spot ratio is important for evaluation of the area measured. The larger the distance from
the object the larger the area measured. Switch on the laser pointer for increasing target accuracy.
Note:
The target must be larger than the instrument's spot size. The smaller the target the shorter the
distance should be.
