Location list
This list shows stored stage positions. When expanded the scrollbar is available. The
Last Position
(the stage
position before latest movement), which is updated during stage operations, is in the list by default.
The position selected becomes the actual active position and it is highlighted in the list and also in the map area (
12
).
Clicking on a position name allows a user to edit it. Pressing the
Enter
key or clicking on a different item confirms
the new name; pressing the
Esc
key restores the old name.
It is possible to load / save stage positions (.stg file) with the use of the
File
menu /
Import
/
Export
functions.
•
When the
Touch Alarm Enabled
check box is ticked, stage movement is stopped, and the Touch Alarm warning
dialog appears whenever the stage or a conductive specimen touches the objective lens or any other equipment
conductively connected to the chamber. This functionality is also used when the stage engines rise their power
above a determined level.
Map area
In the map area, the stage schema is represented showing all stored positions, which are listed in the
Location
list.
