Sample landing

A sample to a tip landing can be started by selecting Landing menu command, that can be found in SPM/Start menu. The same menu can be called by pressing button. Remember that button's menu is equal to SPM/Start menu.

After executing Landing command "Landing" caption appear in the status string of the Parameters window and Stp. motor value will be increasing. This value shows number of steps that were done by the stepper motor (every step is equivalent to 30 nm). When the landing is finished caption "Feedback" will appear in the status string and the slider will somewhere in between the scale. If caption "Feedback" is appeared in the status string, but the slider still resting in bottom position it means that landing didn't performed yet, and the microscope has treated an accidental spike as a feedback signal. If after continuous landing (usually it means that number of stepper motor steps is greater than 500) surface remains unavalable (feedback haven't been activated), "Landing failed" message appear. This message propose to continue landing. You can press "Ok" button to do it.
