3.3.1: Selecting a cantilever
It is very important that the cantilever type is suitable for the operating mode that is used.
Stiffer and shorter cantilevers (e.g. NCLR, Nanoworld or Tap190Al-G, BudgetSensors) are
generally used for the Dynamic operating mode. More flexible and longer cantilevers (e.g.
CONTR, Nanoworld or ContAl-G, BudgetSensors) are generally used for the Static operating
mode.
To change to a different cantilever type:
> In the Preparation group of the Acquisition tab, select the desired cantilever type from
the “Mounted cantilever” drop-down menu by clicking the currently selected
cantilever type.
The various usable types are listed in Section 11.2.1: Specifications and features (page 100),
under Compatible cantilevers.
