THE

 

SAMPLE

53

- If you are operating in Static Force mode, select a CONTR type canti-

lever.

In dynamic mode, the instrument will automatically determine the vibra-
tion frequency used in the dynamic mode. To do this, it uses a measurement 
of the cantilever vibration amplitude as a function of excitation frequency. 
This measurement is not displayed when using the default settings. Never-
theless, it is instructive to see this measurement at least once. To display the 
measurement:

- Open the User interface dialog via the menu ‘Options/Config User Inter-

face...’.

- Select the ‘Standard level’ user interface mode.

- Enable ‘Display sweep chart’ in the Mode Properties section of the Oper-

ating mode panel.

- Click the ‘Set’ button.

The software will now perform a coarse and fine frequency sweep, and dis-
play the results (figure 

Fine frequency sweep

). For more details on the fre-

quency search procedure see section 

The Operating mode panel

 (p.95).

Now restore the default settings:

- Disable ‘Display sweep chart’ in the Mode Properties section of the Oper-

ating mode panel.

- Select the ‘Easy level’ user interface mode.

Fine frequency sweep: Cantilever vibration amplitude as a function of frequency.
