Press the ENT Key to enter the setting.
Background suppression (BGS) excludes the background of
the measurement object from the measurement process.
BGS changes image areas with densities below the lower limit
to 0, and image areas with densities above the upper limit to
255. Image areas with densities between the lower and upper
limits are graded from 0 to 255 so that only images with densi-
ties between the lower and upper limits are measured.
Look at the image and set the upper and lower limits of the
density to eliminate the background.

ment. BGS levels can be set separately for position dis-
placement compensation. → Page 64
If the camera mode is Vertical Composition mode or Horizon-
tal Composition modes 1 or 2, the BGS levels set in Adjust 0/
BGS Levels 01 will be used for both Cameras.
Image areas with densities of 149 or lower
will not be measured and the density will
be changed to 0.
Only image areas with densities between
150 and 255 will be measured. The whole
image is graded from 0 to 255.
