13. Cover the nose opening whenever the camera is not in the vacuum chamber.
D.2 Replace the Open Nose with the Visible Nose
This operation should be performed in a clean room environment to prevent possible
contamination of the CCD array.
CAUTION!
!
Whenever the open nose is on the camera, EXTREME
CAUTION must be exercised to prevent damage to the CCD
array. To prevent contamination, only handle a PI-MTE with
an open nose in a clean room environment. If the camera
must be removed from a clean room environment, cover
the array opening. Note that the camera is even more
vulnerable with no nose in place.
Because the CCD array and/or the bond wires could be
damaged when performing this operation, be very careful
when replacing the nose. Damage to the array and/or bond
wires during such an operation is not covered under
warranty.
Perform the following procedure to replace the open nose with the visible nose:
1. Place the PI-MTE with open nose in a clean room environment.
2. Clamp or support the camera with the CCD array looking up.
3. Loosen each of the eight (8) socket head screws on the face of the nose by one (1)
turn. See Figure D-6 .
