(figure View of the cantilever after manualapproach, left).- Whilst observing the tip sample distance, click and hold untilthe tip is close enough to the sample.The sample should now be in focus. Now use the top view image to find asuitable location to measure on. In the top view, the sample is seen from adirection 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 Videopanel.- If you do not have the Video Module, use the top view lens to observe thesample instead.If necessary, move the sample holder to find a suitable location that is freeof dust particles.Automatic final approachIn 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.View of the cantilever after manual approach: left: side view, right: top view
