> “Check for location tolerances” means that FmNT will check the found
location of the fiducial and compare it to the location where it expected to
find it. If the difference between the two locations is greater than the Location
Tolerance, FmNT will consider the fiducial to be “Not Found.” This ensures
that an incorrect fiducial or other feature is not considered to be a correct
fiducial, and prevents dispensing on parts that are too far away from their
expected locations.

 TIP
 Gain
 The Gain controls the way digital values are assigned to the
analog signal from the camera. Lower Gain values will
increase the contrast of the image and may help to
differentiate the fiducial from the background. However, a
low Gain value may also amplify “noise” in the image.
Therefore, it is recommended that you first adjust the light
level, then adjust the Gain only if necessary.
 The default value of the Gain is 255.
