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,

applications to decrease the overall noise. This can be considered the normal or

Selecting the Pulse Width
1) Press the MENU key once to activate the menu items tab. Press the
