Check illumination
After the working distance is checked, the homogeneity and brightness of the illumi-
nation must be set. For this, you
must not have
anything in the camera’s visual field.
To check the illumination the greyscales are checked in the camera’s horizontal and
vertical alignment on both edges of the image as well as the middle of the image and
the results shown on 6 lines.
The illumination reaches its optimum setting if these lines are as horizontal as possi-
ble and within the horizontal tolerance range marked by 2 purple lines.
You access the operating mode for setting the illumination using the following menu
steps:
