FFC
You can perform FFC measurement only in the contact AFM mode.
In FFC mode, you can measure the change of the friction force due to the torsion

Tip Displacement
Specify the scanning range of the tip in the Y direction.
•
Tip Offset/nm
Specify the offset position in the Y direction. The value in Tip Offset/nm will
be added to the position in the Y direction before scanning. Usually, specify 0.
•
Ramp Direction
Specify the sweeping direction for the distance between the tip and the speci-
men.
Right ->Left: First, the tip sweeps in the right direction, and then it sweeps
in the left direction.
Left -> Right:
First, the tip sweeps in the left direction, and then it sweeps
in the right direction.

Feedback
Turn Feedback on or off.
Hold: Measurement
is
performed with feedback turned off.
Select Friction Force for the FFC measurement because you measure the
change of the friction force when sweeping the tip in the Y direction on the
specimen.
