Thickness
The most common method of adjustment is to measure a
ple 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
to be measured.
Material
If a known thickness of the material is not available, but the
material 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.
