Threshold Display
The threshold display is a graphic representation of the current threshold
setting. It can be adjusted, using the threshold adjustment slide bar, within a
range of 0 to 255 (see the Threshold Adjustments and Mode Selection
section, on page 7–170, for details about the threshold adjustment procedure).
Figure 7.125 shows the threshold display at a level of 128.

Using the slide bar, you can adjust the threshold display to a level that is best
suited for the application. Figure 7.126 shows the threshold display at a level
of 87, which causes the profile tool to detect an abnormality. (In this
example, the abnormality represents a “broken pin” on a connector. As a
consequence, the profile tool will detect two fewer edges than when the pins
are all intact.)
