A.7 Grounding the LS-AFM
There are several grounding options for the LS-
AFM. The green ground wire should be used to
connect the stage with the Ebox. The probe and
sample are grounded by a grounding connector,
which should be attached to the Modes/IO connec-
tion on the back of the stage. A wire can be added
to the ground connector to receive signals from the
probe.
