Check Initial Scan Parameters

For TappingMode in air, set the following initial scan parameters in the Scan Controls panel:

Scan Panel

Scan Rate: 1 Hz
Scan Size: 500 nm
Scan Angle: 0

Feedback Panel

Integral gain: 0.5
Proportional gain: 5

NOTE: The Drive Frequency and Drive Amplitude values were determined during the Cantilever Tune procedure. It is not necessary to enter a value for the Amplitude Setpoint; this will be determined automatically during the engage process, but should be optimized after engage by using Surface Tune.

Other Parameters

Set the Units to Metric.

Channels

Channel 1 Data Type: Height Sensor
Channel 2 Data Type: Amplitude Error
Channel 3 Data Type: Phase
Set Data Scale to a reasonable value for the sample. For example, for a 200 nm step height calibration sample, a reasonable Data Scale setting is 300 nm initially.
Line direction: Trace or Retrace
Channel 4 through Channel 8 Data Type: Off
