For characterization of monolayer graphene sample I am using NAIO AFM in

  • Mode:-Dynamic Force (non-contact) Mode
  • Tip:-    TAP 190AI-G
  • Frequency:- 161KHz
  • Image size:-  45micron

Once approach is done tip status becomes Green and after 2-3 seconds turns Red. Also when image size is reduced to 25 micron tip status turns Green but it is't scanning properly in linear passion. Once I replaced the tip but am facing the same issue again. Please help me to rectify this issue.
