Velocity

E-9
1.
Select or preset the sound velocity almost that of the material.
2.
Select a measured sample whose thickness is nearly the same as the
work-piece to be measured and measure the actual thickness A by other
measuring methods (For example, Caliper).
3.
Use the Minitest 440 to measure the sample and get a thickness B.
4.
Press
key, screen displays as following
5.
Select “Vel. Meas.”, press “
OK
” key. Screen displays as following:
6.
Press
or
key to adjust the sound velocity and make
the measured thickness value B is almost or the same with the thickness
value A. Press “
OK
” key to confirm.
7. Re-measure the sample's thickness and recheck the deviation between
the measured value and the actual value. If the two values are the same,
that sound velocity is the accurate value of the materials.
8. This new velocity will be stored in “Menu-Velocity-Vel. Custom”.
