Ramp Delay
This parameter sets the amount of time to wait with the piezo extended before retracting.
Reverse Delay
This parameter sets a delay to occur each time the piezo is retracted while continuously ramping.
Auto Offset
If the trigger is not achieved within a range twice the ramp size, then the retract will begin without
reaching the trigger voltage. Enabling this parameter allows the software to automatically move the
range to attempt to reach the trigger.
11.3.6 Menu Bar Commands
Capture
The Capture button stores the force plot for Offline viewing. Use other options in the
Capture menu to change a capture filename and for “continuous capture” of all the force plots
collected.
Probe Menu Commands
These commands allow for highly controlled tip movement designed to prevent damage to the tip.
Each of these commands has an icon to access directly from the menu bar.
• Run Continuous—The tip is continuously lowered and raised by a distance equal to
the Z scan size. This is the normal, default motion during Force Calibrate. “Raising”
and “lowering” are relative to your system (e.g., On MultiModes the sample is lowered
and raised beneath the tip; however other SPMs, such as Dimension Series SPMs, raise
and lower the tip to the surface.).
• Run Single—Lowers and raises tip once by a distance equal to the Z scan size, then
halts.
• Stop—Halts all tip movement.
Note: View additional menu subcommands by accessing the advanced Force Mode
command.
