BUTTONS AND CONTROL ELEMENTS
The following particular buttons and control elements have the same
behaviours for all alignment procedures, when available:
• The Start button starts the procedure and proceeds with following
dialogues.
• The End button moves the user to the last step (by clicking the
Next button) to be able to finish the alignment procedure.
• The Contrast / Brightness adjusters enable to optimize the image
quality during alignment.
• The Auto button executes the appropriate alignment action
automatically for a particular voltage / spot / direction (whatever
suitable) with the use of the
Image Recognition software. If this
utility does not recognize image features well, the procedure is
aborted and Warning message appears onscreen. In this case
change the imaging conditions (better focus, slower scanning, or
lower magnification) and try again.
• The Crossover button activates the Crossover mode, where the
onscreen image shows the electron source tip instead of the
sample.
