+====== Dual path measurement ======
+In some regimes, e.g. [[mfm|MFM]] or [[amkpfm|AM-KPFM]], the measurement has to be performed in two steps, first scanning the topography and then some signal slightly above surface.
+To enable this, use the "Lift" tab in the main window (in Scan settings area). When non-zero number of lifts is enable, Gwyscope automatically adds channels for lift data, so they can be accessed from drop down menus in the channel and graph visualisation and are automatically stored when storing the data.

+Note that positive lift value means "above surface" while negative lift value would mean that the probe is pressed towards surface.
+Lift mode works only for raster scans at the moment.
