If the surface of your sample is made of the same material as the material of

Press the GAIN key (
), and then decrease the gain with the knob in order to
keep the entire crack signal within the screen area.
A good practice is to set the signal’s maximum deflection to 10 % of the screen’s
horizontal deflection (see Figure 5-15 on page 131).
