A FIRST MEASUREMENT

- 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 measure-

ment of the cantilever vibration amplitude as a function of excitation

frequency. This measurement is not displayed when using the default set-

tings. Nevertheless, 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 Software Reference, section Operating mode

panel.

Now restore the default settings:

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

ating mode panel.

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