Q: Is it possible to scan below 0.1Hz in NanoScope

A: Yes, this is a user selectable setting, however, whenever in a manual mode (ie not ScanAsyst) you will not be able to adjust parameters within a scan line (ie 100s for a 0.01 scan); ScanAsyst will autoupdate within a line.

To change the limit, adjust the "minimum scan rate" parameter in the Calibrate/Scanner X/Y menu. See figure.

Is there any data on how reliable going below 0.1Hz is?  What is the minimum scan rate you would reccomend without going outside the limits of the controller?

Nabil,

Slower scanning actually improves your data somewhat as you get more averages per datapoint. You main issue is not the control system by any means but rather thermal drift and the fact that yoiu have to wait for quite a while for some commands to happen.
