Defect Sizing – Auto Snapping
There are two modes for sizing defects, auto snapping and manual snapping. In auto snapping
mode, the Bx and Bz sizing lines automatically snap to features as you move the active window.
The active window is moved using the left/right arrows and the width of the window is adjusted
using the up and down arrow.
Figure 14 Defect Sizing - Manual Snapping
In manual snapping mode, the Bx and Bz sizing lines can be adjusted manually by the operator. F2
button can be used to toggle between the Bx and Bz chart, the left/right arrows are used to move
both lines and the up/down arrow moves just right line in the Bz and the Depth line in Bx.
The typical procedure (using Figure 14 as an example) would be to use left/right arrows to line up the
Trough and Background lines then up/down arrows to line up the Peak and Depth lines.
