Hello dear SPM helpers. Fairly basic one here. My nanoindentation probe ( DNISP I believe) is bent back, as in it looks like it suffered too much force at some point. As such the lazer light on the Dimension or Multimode essentially just returns straight back up as opposed to heading toward the photodetector - the bend is 10-20 degrees I guess. Question

Hello Wang, Thank you for that - it makes sense. My email is karamathj@hotmail.com for future correspondance. I would be very interested to here from you. Kind regards, James K

Dear experienced users!, This is probably embarrassingly simple, but here goes... I want to know what amplitude, in nanometers, I am tapping with. I set my tune target to 1 V or thereabouts, the system seems to decide what setpt to use (I try to set it as close to 0.9 V or so to minimize forces, but it always seems to engage lower than that).

Dear experienced AFM users!, I am basically trying to understand why, when I try to calibrate the deflection sensitivity during a force curve analysis (by pushing a DNP standard contact probe into a very clean glass surface) I get different values literally every 10 seconds... 54.8 nm/V.... 56.4 nm/V... 53.3 nm/V... There is no drift in the values

A somewhat related issue I am having. I see a variation in sensitivity from curve to curve without changing anything! This can be 10-15% variance over the course of 10 minutes - random numbers, not drift. I am using a standard DNP probe (standard tip) and trying to calibrate the sensitivity on cleaned glass in pure water (Nanoscope IV controller and
