To "undo" the deflection sensitivity calibration just go to Tools>Calibrate>Detector and type 1 "" for the deflection sensitivity (or amplitude sensitivity or amplitude error sensitivity in tapping mode). Another way is to look for the Units parameter in the scan parm list or ramp parameter list and set it to "Volts"

Thanks for the example files! It looks as if the export units issue has been fixed in the latest version of Nanoscope Analysis. You can get a copy by following the directions here: NanoScope v8.15x to v8.15R3 Upgrade Procedure.pdf The v5 compatibility issue is still a problem. I will ask software to take a look at what we can do about it. Thanks for

Yes. Look in the menu under Tools>Options>Classic gain and setpoint mode. If it is greyed out, clicking on the scan parmlist in scan mode prior to going to the menu should help. --Bede

Good point. I will talk with software and see if we can make this clearer. --Bede

There are several reasons that this might occur: The elastic model is inappropriate due failure of geometric assumptions. The DMT model assumes that the tip shape is spherical with a radius R>>deformation depth. If this is not the case, you may want to try a Sneddon cone model, or some other model. During the experiment, your tip shape may be

That should not be possible unless you are using some kind of filter like a plane fit or a flatten on the data. If you have not done anything to modify the data offline, please check and see if your "Offline planefit" in Nanoscope realtime is set to "Offset" or "Full". Depending on the type of filter that was used, you

That definitely looks like debris is being picked up by the tip, causing a step. Additionally, it looks like you have used a second or third order flatten or a realtime "Bow" fit, causing the steps to turn into arched scan lines. Please take a look at the offline manual section on flattening. --Bede

Can you provide a little more detail? What software version are you using? On what microscope? I'm assuming that you typed the number into one of the cells in the scan parmlist. Did you press enter? Sometimes I forget to press enter and I just click elsewhere. This does not always work... --Bede

Can you send me a copy of the raw files that exhibit these issues? My email address is firstname dot lastname at bruker dash nano dot com. Thanks! --Bede
