NOTES
Work crew should initial each task that they work on.

Supervisor should indicate the date as each task is completed.

QC person should fill in the report for each QC task. The QC tasks must be completed before subsequent tasks are started.

Work crew shold fill in the materials list for all items used.

Note any problems, deviations from procedures, suggestions, etc. in the space at the bottom and on the reverse side of pages.

NOTES:  1.2  The edges of master plates are asymmetric with one rounded edge and one sharp edge, presumably due to the orientation in the punch.  The plates alternate so that there are alternate wide and narrow slots for the profiles.  The narrow slots are often difficult to get profiles into, and the profiles are often loose in the wide slots.

NOTES: 1. Measure Tile Slot 1 at the bottom of the slot and Tile Slot 11 at the top

(where the widths are assumed to be minimum)

    1. Required shims make the minimum slot width in the range 4:4.5 mm
    2. Gaps are numbered starting at the ITC end.

Some fibers have abrasions on the cladding - I don't think it is worth replacing them
No
           
           

NOTE: Tiles are numbered from the beginning of the cell, starting at the tile closest to the ITC end of the module. Count every other profile to count the tiles. Odd tile layers start at the cell boundary (count from the first profile), even tile layers start with a spacer plate (count from the second profile). The tile counting stick makes it easier to locate the tiles.
