If the angle display value does not lie between 179.98° and 0.02° ,
realign the camera.
ü A calibration master gauge or tool for which the contour is paral-
lel to the vertical axis of the camera is inserted in the tool mount-
ing.
1. Release the locking of the quick adjustment, move the tower
and optical unit into position.
2. Using the infinite fine adjustment, move the camera into the
blue-white rectangle of the measurement field.
3. The angle display with show the difference between the vertical
contour of the calibration master gauge and the vertical axis of
the camera.
» The value must lie within +/- 0.02° tolerance, i.e. between
179.98° and 0.02°.
» If the value is not achieved, align the camera.
4. Using a 3 mm hexagon L-wrench, release the cover of the anti-
rotation arm and tower.
5. Using a 4 mm hexagon L-wrench, release the fixing screws on
the anti-rotation arm of the camera.
6. Cautiously rotate the camera until the maximum permissible
value is achieved.
7. Tighten the screws.
» The camera is now aligned.
NOTICE! During alignment do not disturb the working dis-
tance of the camera. The working distance from the camera
housing to the centre of the tool mounting must be
108mm.
8.5.3. Pixel calibration of the camera
ü A tool/calibration mandrel with a ground edge is inserted.
1. Using the dynamic focus display [} Page 22], rotate the tool/
calibration mandrel to the largest displacement.
2. Press Next point to start the pixel calibration.
» A green rectangle appears on the screen.
3. Using the infinite fine adjustment to move the calibration edge
into the green rectangle.
4. Press Next point to continue the pixel calibration.
