6. EASY GRAPHIC USER INTERFACE - INITIAL SETUP
Before you can operate the SVS2 system, you will have to perform a preliminary configuration
procedure. The "Easy GUI" lets you complete the procedure in three steps.
Each step is identified with a number: your progress through the configuration process is visually
identified by a red label.
During the first step, you have to choose how to set up the inspection; you may set up an inspection
from scratch or select an existing inspection and change its parameters as required.
In the second step, you have to set the triggers (to set inspection time instant) and tools (to perform
controls and/or take measurements).
During the third and last step, you will have to set up the outputs and start a test to assess the
effectiveness of selected controls.
Let us now discuss the individual steps with their options and selectable parameters.
6.1. General considerations
A correct configuration based on the acquisition of a good-quality reference image is a prerequisite to
ensuring accurate inspection.
The term inspection means the set of operations the sensor performs to check the features of an
object for compliance with certain specifications.
Each individual object is compared to the reference image to determine whether it meets the
specified requirements.
For this reason, the sample in reference image must have neat contours and clearly visible features.
Here are a few tips to facilitate correct configuration:
• determine which product feature you want monitored;
• provide correct, even lighting: minimising the incidence of ambient light on the target area helps
ensure correct image acquisition;
• provide sharp contrast between target object and background;
• choose the tools (or "controls") to be used for processing accurately, so as to provide the best result in
the easiest, fastest way;
• accurately set the control parameters for the controls;
• it may be a good idea to run some preliminary tests to determine if any features are hard to identify
and set tolerances accordingly;
• compare results to identify any inconsistencies.
