4-2 Taking Measurements and Analyzing Data
SETTING THE MEASUREMENT OPTIONS
Before taking a manual measurement or an automated series of measurements, you must make
selections in the
Measurement Setup window (see Figure 4-2 ). If you save these selections as a
Vision recipe that you designate as the default, the system will automatically apply them to every
future measurement. For instructions, see
Creating a Vision Recipe on page 4-18 .
NOTE –
If the Measurement Options window does not appear, click the Measurement
Setup button on the Ribbon.

Scan Type: Select from the following:
•
Standard Scan: A normal scan type in which the scan is performed across the surface of a
sample. Because the tower is nulled before each scan, each successive scan has its own
reference point.
•
Static Tower Scan: A special scan type in which the scan is performed across the surface of a
sample, but the tower is nulled before only the first scan. Each successive scan therefore uses
the same initial reference point.
•
Static Scan: A special scan type in which the scan is performed at the same point. (The scan
stage does not move.) The tower is nulled before the scan. This scan type is primarily used for
determining the noise and drift of the system.
•
Map Scan: If your system includes the 3D Mapping Option, select this scan type to measure,
analyze, and view surface contour data in three dimensions (X, Y, and Z).
