4.3.2 Calibration on known Material / Determinate the US velocity
To determine the velocity of an US wave in a material with a known thickness, use the "Calibrating
on" function in the setup screen.
Enter the thickness of the sample with "Edit" and start the calibration process by pressing "Run".
The sample thickness should be within 2.0 - 80.0mm (0.078 - 3.15 inch).
Once the data acquisition is finished, the velocity and material can be saved and added to the
database of the instrument (see 4.3.1.).
