Cal Lock
Thickness
The most common method of adjustment is to measure a sample
of known thickness. Select a reference standard of material as
close as possible in composition to the intended application. For
best results, the thickness of the reference standard should be
equal to or slightly greater than the thickness of the part to be
measured.
Material
If a known thickness of the material is not available, but the mate-
rial is known, this quick adjustment allows the user to load one of
several preprogrammed material velocities.
Velocity
If the sound velocity for the test material is known, the Gage can
be adjusted to that specific sound velocity.
2 Pt Adjust
A 2-Point adjustment allows for greater accuracy while
simultaneously adjusting probe zero. Select two reference
standards as close as possible in composition to the intended
application. For best results, the thickness of the thicker reference
standard should be equal to, or slightly greater than the thickest
part to be measured. The thickness of the thinner reference
standard should be as close as possible to the lower end of the
expected measurement range.
When checked, the icon appears and the current Cal settings
are “locked” to prevent further user adjustments. Uncheck to make
further adjustments.
