Informational feedbacks 1. I need to document more thoroughly. - I'm 100% agree with that. 2. Regards to the images, take the images in both way, using both print screen and easy scan. (This might possibly help reducing the white lines in the image)  Question about I gain: How do I know which value gives the appropriate image? (since I don't think I can distinguish whether or not the images are good or bad) 3. Maximize the i gain to increase the sensitivity. Start at a higher level and find the appropriate gain. 4. Minimize the Z range for better images since the step height is approximately .2nm. 5. Change the tip often.
