provides four simple methods for setting the sound-velocity outlined below:
Known Velocity
If the material velocity is known, the user may wish to simply enter the velocity
number into the DFX-8, rather than have the DFX-8 calculate the velocity value using
a known thickness on a material sample. The steps for entering the velocity are
outlined below:
Using a Known Material Velocity
1) Press the MENU key once to activate the menu items tab. Press the MENU
key multiple times to tab right and the ESC key multiple times to tab left until
the CAL menu is highlighted and displaying the submenu items.
Alternatively, press the LEFT and RIGHT arrow keys multiple times
using the left button wheel.
2) Press the UP and DOWN arrow keys multiple times using the left button
wheel to scroll through the sub menu items until VELOCITY is highlighted.
3) Press the ENTER key to display the Digits Edit Box.
