>
Scanner
).
Note:
In the
Microscope Select
dialog box, you can add a new set of hardware
con
fi
guration parameters by clicking
New
or edit the parameters of the selected
microscope by clicking
Edit
. The parameters include things such as the
controller, extender, and vision system.
4. Select
OK
when you finish changing all microscope parameters.
5. In the
Other Controls
panel, select the
Microscope Mode
.
•
For TappingMode, set the
Microscope Mode
to
Tapping
.
•
For Contact AFM, set the
Microscope Mode
to
Contact
.
6. After this is completed, click on the
Scan Controls
panel to access the most important
control settings used for imaging.

MultiMode SPM Voltage Meters
•
A complete description of the signals coming into and out of the MultiMode SPM is
available in Support Note 210,
NanoScope Signal Access Module (SAM)—Description
and Use
. The SAM is normally used for accessing these signals directly. A brief
description of the SPM’s voltages and their interpretation using the meters on the front
of the base is provided here for quick reference.
•
The MultiMode SPM base is equipped with meters which indicate voltage coming from
the four-segment photodetector. The photodetector array is represented here:
•
The MultiMode SPM’s bottom, (
SUM
) meter indicates the
total voltage generated by
the photodetector
. That is, the combined voltage of photodetector segments. This is
displayed during all modes (except STM when all meters are off).
