Hello, we have some problems with our Multimode AFMs. To me, it looks like a minor issue, maybe someone of you knows what to do. Both AFMs (1x MM AFM + Nanoscope IIIa; 1x MM AFM + Nanoscope IV) work flawlessly in contact mode. Tapping mode itself also works, but cantilever auto tune fails. In the tuning window, the amplitude always shows a "baseline"
