4. Remove the threaded cap from the calibration (CAL) port.
5. Connect the clean calibration fiber to the CAL port, aligning the key on the fiber connector with the notch on the
CAL port connector. The fiber should be routed in a helical pattern as shown below to avoid kinks.

6. Remove the rubber cap from the MT style collection fiber connector. Lift and hold the cover of the collection
(COLL) port as the fiber is connected. Align the white dot on the MT style fiber connector with the white mark on
the COLL port and insert the fiber connector until it clicks into place. The fiber should be routed in a helical
pattern as shown below to avoid kinks.

7. Remove the excitation fiber clamp by loosening the clamp screw with a 3/32" ball driver (provided with analyzer)
and sliding it out of the way.
8. Remove the threaded cap from the excitation (EXC) port.
