ADDITIONAL FEATURES OF THE DFX-7
11.1 Pulse Width
The
DFX-7
has a square wave pulser with adjustable pulse width option. 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. When additional energy is
needed, more penetration, the
THIN
and
WIDE
options may be necessary. The
standard setting is
THIN
. 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
TUNE
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 the
measurement screen.
