Note: For software versions 4.23 and lower set Interleave scan to Lift and switch Interleave mode to Enable in the Interleave Controls
panel
8 Set the Channel 2 Scan line to Interleave to display interleave
data
Note: For software versions 4.23 and lower,
there are no separate Analog 2 setting in the
Interleave Controls panel Set Analog 2 in the Feedback Controls panel to 0 volts.
9 In the Interleave Controls panel set Analog 2 to the desired
voltage
Note: Applying a voltage during the main line
can make Tapping Mode operation difficult
10 Optimize the Lift scan height For high-resolution, set the Lift scan height as small as possible without crashing the tip into the
surface There are two ways to determine if the tip is touching the surface:
• If the tip crashes into the surface, it typically creates bright
or dark specks or streaks in the image Also, if the Lift scan height is set extremely low, the tip may continuously “tap”
on the surface during the LiftMode scan
• Toggle between the Interleave and Main scan lines for the
phase image If the two images appear similar this indicates the tip is continuously tapping on the surface during the
LiftMode scan Increase the Lift scan height until the Interleave scan image changes indicating that the tip is
oscillating above the surface and not continuously tapping
11 Adjust the sample or tip voltage to confirm that contrast is due to electrical force gradients
