Is the Z stage position in the approaching-possible range?

unit to AFM.
g before approaching
re performing approaching, check whether the preparation has been completed
•
Has coarse approaching been done in such a way that the distance between the
cantilever tip and the specimen surface is within 0.3 mm or less?
•
Is the SUM value of the AFM amplifier unit as negative as possible (–1.0 V to
the value depends upon the cantilever used)?
After checking these points, set the indicator selection knob on the AFM amplif
