Approach
The Approach page is where you can start an approach of the sample to the tip. There are two
controls: “Approach” and “Retract”. Clicking on the Approach button initiates an automatic
approach. Clicking and holding on Retract will move the sample platform downwards.
The Approach page also has an indicator for the Motor status and the Approach status.
Ensure that the target area of your sample is below the nGauge AFM tip. Click the
Approach
button to initiate the automatic approach of the sample to the probe tip. The sample platform will
rise quickly and then slow down for a final approach once the sample gets very close. When the
tip engages with the sample, the Approach status will change from “sample not in contact” to
“approach complete”.
To stop the approach before it is complete, click on
Pause
. You can retract the sample platform
by clicking and holding on
Retract
.
