• Fre
quency Shift Direction
In the adjustment operations mentioned above, set the shift direction whether you
shift the frequency to the lower frequency or higher frequency from the resonance
frequency. The nature of the force that the cantilever receives cha
the frequency shift direction (repulsive force or attractive force).
• Start Frequen
Set the start and stop values at kHz order in the frequency scan for detecting
resonance.
FMD Mode Setting
When you select FMD in the AFM Mode on the upper right of the dialog, AFM Mode
c hanges to FMD mode.
•
Excitation Voltage
In the automatic adjustment sequence, the software scans the frequency to search
for the resonance point of the cantilever, and sets the excitation voltage of the
cantilever at the resonance point. If the amplitude signal (RMS signal) scales over
the limit range, decrease the setting voltage.
• Start Frequency/Stop Frequency
Set the start and stop values at kHz order in the frequency scan for detecting
resonance.
