Jumps in Measured Depth¶
Symptoms¶
- Sudden jumps in the measured depth from one read line to the next one.
- Featureless or faintly sinusoidal topography in patterned areas.
Cause¶
Loss of contact between tip and surface during reading. Note that when writing 3D structures the loss of contact might only occur for the deeper levels. For further details consult the section on setting the Backward (reading) height.
Solution¶
Decrease the Backward Height and/or increase the Read Force to keep the tip in contact during reading.
