7.2.16 Engage
• Select Motor > Engage , or click the Engage icon.
• Once engaged, refer to the appropriate chapter in this manual for further instructions for
the mode you are using (e.g.
Contact AFM: Chapter 8 , TappingMode AFM: Chapter
9 , etc.)
7.2.17 Withdraw
When imaging is complete, withdraw the tip by selecting Motor > Withdraw , or the click
Withdraw icon. This typically raises the tip 1mm above the sample.
Although the 1mm withdraw distance provides enough clearance to loosen the dovetail and remove
the AFM head, if further distance is desired perform one of the following:
• Select Stage > Focus Surface to raise the Z-stage with the trackball.
• Execute Withdraw multiple times.
• Select Stage > Load New Sample .
Note: It is impossible to move the Dimension head if the laser sum signal is too low.
