Comparison Measurements
Comparison measurements rely on the known dimensions of an object that has been set
in the field of view either by the manufacturer or by the probe. The XLG3 processor uses
these known dimensions as a reference scale for measuring an unknown target.
You can take comparison measurements on a frozen image or on a recalled image that
was saved in measurement mode.
