Lift setting button
This button opens the setting dialog that sets the amount of the Z scanner control at
lift up and the cantilever-oscillation voltage at lift up.
Lift Height
ip during timing of the lift scan.
This lift mode performs lift-up operation for every measurement point. Since the up
and down movements of the tip are performed too often, even the measurement of
topography images in vacuum has the drawback that it is liable to become unstable.
•
Line by Line Lift mode
This lift mode performs the lift-up operation for every scan line. Since the up and
down movements of the tip are performed for every scan line, you can obtain the
stable shape and magnetic force images.
You cannot use the Line by Line radio button if the Digital Control MFM unit
is not installed or, even if it is installed, when you do not set it by using the De-
vice Setup dialog.

Lift Output Amp/V
You can obtain a clear MFM image by changing the oscillation voltage to the
cantilever while you lift it up. Here you set oscillation voltage to the cantilever
(Output Voltage (V) in the Cantilever Adjustment window). This setting works
only while you lift up the cantilever.
