Shadow Measurements

Shadow measurements require the use of ShadowProbe measurement tips, which project
a shadow onto a target. To measure the target, the XLG3 processor uses triangulation
based on the shadow’s location. You can take shadow measurements on a frozen image
or on a recalled image that was saved in measurement mode.
