During PeakForce capture I set up the Peak Force Amplitude to a certain value = A. PF-Amplitude is the zero-peak distance, i.e.the length of extension or retraction path. So, in online force monitor I observe curves F(z) exactly in the given range of z = 0....A. However, when I open the obtained *.pfc file in Nanoscope Analysis (v.150 or 1.60) the range
