grated optics. The tip should not come closer to the sample than a few
times the cantilever width. (figure

approach , left ).
- Whilst observing the tip sample distance, click and hold until
the tip is close enough to the sample.
The sample should now be in focus. Now use the top view image to find a
suitable location to measure on. In the top view, the sample is seen from a
direction perpendicular to its surface (figure
View of the cantilever after man-
ual approach , right ). To use the top view:
- If the Video Module is installed, click in the Video
panel.
- If you do not have the Video Module, use the top view lens to observe the
sample instead.
If necessary, move the sample holder to find a suitable location that is free
of dust particles.
Automatic final approach
In the last step, the tip approaches the sample until the set point is reached.
First check that you are using the right operating mode and cantilever:
- Click in the navigator to open the Operating Mode panel.
