Precision: Adjusting the inspection precision of the sensor
The Precision setting influences the width of the tolerance band and the in-
spection precision.
The Precision item in the menu can be accessed in two manners:
• Directly following Teach Model
• Through selection in the Training menu
The tolerance bandwidth and inspection precision are directly dependent on
one another:
Note
The sensitivity to ambient light is increased when "Precision High" is
selected.
In such a case, make sure that the lighting conditions in the environ-
ment of the sensor remain constant.
