11.5 Material Velocity Charts
The
DFX-7
has two material velocity charts built into the gauge with both longitudinal
and shear material velocities. It should be noted that in order to display the chart
containing the shear wave velocities the
TRIG
mode must be activated, as we’ve
assumed an angle beam transducer will be used for the inspection process. The
procedure is listed below:
Selecting a Basic Material Type
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.
2) Use the
UP
and
DOWN
arrow keys to scroll through the sub menu items
until
MAT
is highlighted.
