OPERATION
BEFORE STARTING THE MEASUREMENTS
Distance (D) : Spot Size (S)
The DISTANCE : SPOT RATIO is important for the evaluation of the area to be measured. The larger the
distance from the object the larger the area measured. Power on the laser pointer for increasing the
target accuracy.
Note:
The target must be larger than the instrument's spot size.
The smaller the target the shorter the distance should be.
