Ramp Menu Definitions

Icon Control Description
Ramp Continuous The tip is continuously lowered and raised by a distance equal to the Ramp size. This is the normal, default motion during Ramp Calibrate. “Raising” and “lowering” are relative to your system (e.g., On Dimension Series SPMs, the tip is raised and lowered to the surface; however, other SPMs raise and lower the sample beneath the tip).
Ramp Single Lowers and raises tip once by a distance equal to the Z scan size, then halts.
  External Trigger Not available
Stop Halts all tip movement.
 

Retract

The Z-axis piezo retracts to its limit in preparation for Approach Continuous. This command does not initiate motor movements.

Continuous Approach

The tip lowers to the surface and raises in a controlled series of steps, then indexed by the Z step size (see Scan Mode panel) distance. This process continues downward until the tip encounters the surface. When tip deflection exceeds the Threshold Step amount, Continuous Approach halts and the resulting force curve displays.

Approach Single

The tip is lowered to the surface and raised in a single, controlled step. This process is halted if the surface is encountered by the tip, causing deflection exceeding the Step threshold amount. The resulting force curve is displayed.

NOTE: For both Approach Continuous and Approach Single, if Start mode = Motor step, the motor is stepped towards the surface, not the Z piezo.
Auto ramp Begins auto ramping as defined by the parameters specified in the Auto Panel.

Plots Only
