５ MEASUREMENT OPERATION
Surface Potential m
• Source signal
Since the source signal of the Surface Potential measurement tab window is set for
measuring
at 256 × 256. When the measurement starts, the images appear as follows:
• Source Gain
The same as that in the AC-AFM tab window.
• Setting button
This button opens the KFM setting dialog that is used for measuring surface poten-
tial.
• KFM Feedback on
If you check this check box, KFM feedback of the bias voltage starts. When KFM
feedback starts, the CPD signal is output from the AFM amplifi
KFM measurement.
