Force Curve - Update Sensitivity

NanoScope software allowws for the updating of sensitivity on Force Curvespreviously captured files. The goal of updating the sensitivity of a Force Curve is to calibrate the Y axis (Cantilever Deflection for Contact Mode or Amplitude for Tapping Mode).

Update Sensitivity Procedure

  1. When updating sensitivity it is important to use the Z Sensor channel (Height Sensor) if available and to set the Active Curve to Retract. When placing cursors, it is preferred to place them such that they are over a linear section of the plot (not too close to the pull off or peak force). Additionally, select as long of a section as possible.
NOTE: When using the Update Sensitivity function, it is assumed that there is no deformation of the tip or sample. This requires a hard sample for the results to be valid.
  1. After the Force Curve file has already been opened and the cursors placed, click the Update Sensitivity icon or select Plot > Update Sensitivity from the Menu Bar, as shown in Figure 1.
