５ MEASUREMENT OPERATION
■
Scan Options
When the optional Viscoelasticity Lateral Modulation FFM (Lock-in Amplifier) is
installed in the instrument, use the Scan Options dialog box for setting the external
instruments. A detailed procedure for setting the Lock-in Amplifier is provided later.

Lift
Clicking on the Lift button opens a dialog that you set at the lift operation.
The Magnetic Force measurement is an image acquisition method that acquire
magnetic images as well as topographic images by detecting bending caused by the
