*Before taking any fibers out of the dark room, open the [https://docs.google.com/spreadsheets/d/11dipDk7WZ5PHp3xFHyUtVzUyJhcY9ewnyDf5FEbtbig/edit| Fiber testing spreadsheet] and click on the tab titled "Fiber Tests 2." In this tab, the fibers to be tested have been put in the appropriate chimney slot column and in the matrix placement of fibers.

*Before selecting fibers from their dark room, don a pair of powder free gloves and place the popsicle stick with the testing clamp at the table you will be working.

*Once each fiber has been pushed into the rigid material, the fibers should be held in place by twisting the wire tightly around them. The rigid material should be carefully moved away to determine if the fibers are flush. If not, repeat the process again.

*After you are sure that the fibers are properly separated and flush with each other, make sure the wires and clamp is tight so that no fibers can change position.
*'''Check that all electronics are off before opening the dark box! Have a grad student or lab technician remove the board after opening the dark box.''' Carefully unscrew the main dark box opening and dock the popsicle stick into place by tightening the two screws underneath the popsicle stick to secure it into place. The wood has been depressed in the place where the popsicle stick should be. '''Do not modify the position of the pulsar at any point during the loading process!'''

*Guide the fiber ends over the edge and using the Google Document, place the fibers into the chimney in the correct order. '''Have a grad student or lab technician check the fibers at this step. The fibers cannot be too far into the chimneys or else they will damage the SiPMs when the board is replaced. A grad student or lab technician must put the SiPM board back into place.'''

*Let the black plastic divider down and Velcro the top opening shut so no light passes from the pulsar side to the SiPM side of the dark box.
*Close the main dark box opening and ensure that it is light sealed.
*Turn on the electronics and begin the fiber test.
