Chapter 13 Additional Features

13.1 Pulse Width

The MINI-MAX is equipped with an 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. 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:
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 WIDTH is highlighted.
3)
Use the LEFT and RIGHT arrow keys to scroll the Pulse options.
4)
Once the correct Pulse is displayed, press the MEAS key to return to
measurement screen.
