|Roughness measurement can be done in both Contact, Tapping and ScanAsyst mode. We recommend '''ScanAsyst mode''' because of less chance of (non-uniform) deformation of the sample and less tip wear - and because of ease of use. However it also works fine in tapping mode.

|For Topographic measurements with no steep/abrupt steps we also recommend '''Tapping mode''' on most samples. Only on very soft samples (e.g. cells) we recommend ''ScanAsyst'' due to less chance of (non-uniform) deformation of the sample - or if you need QNM data. We mainly recommend '''Tapping mode''' because we experience less problems when the tip end is slightly broken.

|For large scan areas where you prioritize to scan fast then you can use '''contact mode'''. Here you can scan with scan rate of up to 2.43 Hz
