IMPROVING MEASUREMENT QUALITY

Ideally, the XY-plane of the scanner has already been correctly aligned with

the sample plane using the three Levelling screws on the Scan head. How-

ever, this alignment can not be performed once the automatic approach has

been done, because this will damage the tip. During measurement, the

measurement plane should therefore be adjusted electronically using the

parameters ‘X-Slope’ and ‘Y-Slope’.

To find the correct values, use the following procedure:

- The slope correction is only available with the Standard level and the

Advanced level user interface mode. Open the User interface dialog via

the menu ‘Options/Config user interface, and select one of these modes.

- Measure the slope in the Line graph using the angle tool (see Software

Reference). Use a single click to measure the angle relative to the X*-Axis.

- Alter the value of ‘X-Slope’ in the Imaging options of the Imaging panel

until the x-axis of the scan line lies parallel to the X-axis of the sample.
