ADDITIONAL FEATURES OF THE PVX
9.1 Pulse Width
The PVX has an adjustable pulse width option, located as a submenu item in the
PROBE tab group. Pulse width, refers to the duration of time the pulser is left on.
This time results in increased energy sent into the test material. There are three
width options (SPIKE, THIN, and WIDE). The SPIKE setting may be desirable for
high resolution and general applications to decrease the overall noise. This can be
considered the normal or standard setting. When additional energy is needed, more
penetration, the THIN and WIDE options may be necessary. The procedure to
change the pulse width is outlined below:
Selecting the Pulse Width
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 PROBE menu is highlighted and displaying the submenu items.
2) Use the UP and DOWN arrow keys to scroll through the sub menu items
until PULSE is highlighted.
3) Use the LEFT and RIGHT arrow keys to scroll the Pulse options.
4) Once the Pulse is displayed, press the MEAS key to return to measurement
screen.
