I am using Agilent Technoligies 5500 AFM microscope (Model: N9451A) and have some problems. It is very complicated to approach the tip to sample because it is lying on the sample or is very high from the sample. If I finaly get right possition of the tip, the image quality is so low, that it doesnt match the real one. Could you give me some advices what should I do? How to set parametres correctly?
Also I have doubts about scanning probe. I'm not sure if it works right. Is were any method to check it?
Thank you for the answers!
