4-13 ITEM Overview (Defect)

Use this item to detect dirt, scratching, chipping, burrs and other defects on
the plain measurement target. The defect value and position of the defect
which has highest defect value are output. And the number of defects are also
output.

Number of defects

The extent of the defects is calculated in subdivided
regions, and regions at or exceeding the defect
threshold are output as the number of defects.

Even if you see only one defect on the screen, the
number of defects is often more than one.
