The X-axis-position adjusting knob shifts 0.5 mm per revolution, and the
Y-axis-position adjusting knob shifts 0.25 mm per revolution.
When the following result is obtained, calculate the calibration value from this
graph.
0.5
• Distance d [mm/V]
Enter the distance of 40.0 between the cantilever and the photodiode in this input
box.
• Reference V
Enter the Friction Force signal value that is obtained when the force applied to the
cantilever is zero in the Reference V0 [V] input box.
