A few changes in SmartScan window can be noticed after a new "Project" is created.
(1)
Items needed to be defined for each scan are shown under the "Project" name.
(2)
Scan set up guidelines are added to the "Wizard" pane on right.
(3)
Some items in the guidelines already have checkmarks. This means some default values
are assigned, and the scan can start with those default values.
(4)
Unless every item on "Wizard" pane is checked, the scan cannot be performed, as the
redcross mark shows at "Run scanning".

Calibrate Probe Z Offset
Most probes from API have same length, however, slight length variation may occur due to the
probe assembly or probe mounting. Since it is important to know the actual scan distance (height)
between the probe tip and the DUT surface, the software has to know where the probe tip is
relative to the predefined origin. The origin is defined at API during hardware calibration. Z
