５ MEASUREMENT OPERATION
■ FFM Observation
In the ordinary contact mode, the scanning direction is parallel to the cantilever axis. In
the FFM image observation, on
the cantilever axis. The cantilev
acting between the specimen surface and the cantilever tip. The FFM measures the
friction force of the specimen surface from this torsion of the cantilever.
The following is the procedure for observing an FFM image in the Advanced contact
mode.
1.
Click on the
select 2 Inputs from the pull-down menu.
This operation acquires and displays two images simultaneously. When you observe
an FFM im
image.
2.
Click on the Scan Area button in the Scan frame to display the scan area
window; then, double-c
the keyboard.
Now, the specimen is scanned in a direction orthogonal to the cantilever axis.
3.
Click on the
Friction Force from the pull-down menu.
5-114
the other hand, the scanning direction is orthogonal to

button in the Acquisition selection box in the Scan frame and
age, also acquire a topography image so as to compare it with an FFM
lick on the Scan Angle input box and enter 90 using
button in the Display Source—2 selection box and select
