Stereo Measurements
Stereo measurements require the use of StereoProbe measurement tips, which capture
stereoscopic images of a target — two pictures of the same target from two different
angles. To measure the target, the XLG3 processor uses triangulation based on these two
side-by-side images.
You can take stereo measurements on a frozen image or on a recalled image that was
saved in measurement mode.
