Force Imaging
Force Calibration Control Panels and Menus
212 Dimension 3100 Manual Rev. D
13.3 Force Calibration Control Panels and Menus
The Force Calibration Control window (see Figure 13.3a) manipulates the microscope in Force
Calibration mode. The parameters control the rate, start position and amplitude of the triangle
wave applied to the Z piezo. You can also adjust the Setpoint value of the cantilever deflection
voltage used in the feedback loop during imaging. The Capture button stores the force curve for
Offline viewing. Some parameters influence the operation of the microscope during imaging; most
of the menu parameters affect only Force Calibration mode.
Figure 13.3a Advanced Force Calibration Control Window (Contact Mode AFM)
There are 2 methods to enter Force Calibration Mode:
View > Force Mode > Calibrate will open a simplified subset of the parameters and
commands available.
View > Force Mode > Advanced includes the full set of available parameters and
commands.
Additionally:
View > Force Mode > Step enters force mode with the parameter start mode = step
and the piezo fully retracted.
View > Force Mode > Volume enters Force Volume Mode.
Items in the Force Calibration Control Window are discussed individually below.
