Measuring the Sound Speed
The Thickness Gage is capable of measuring the sound speed of a
material if the thickness of the material is known (at a flange, for
example). Use the steps below to measure the sound speed:
1. Press the [CAL] key to enter the Calibration Menu, and then
press [F3] to select “WALL”. The screen should appear
similar to that shown in Figure 9-4.
2. Press [F3] to select “SNDSP.”
