11. Observe the indicated integration time. If the observed integration period is <100
milliseconds AND the shape of the red current spectrum has no major differences from
the factory spectrum, both fibres are undamaged and will not require replacement. . If
the lamp was replaced <8 months ago (BA7195 standard lifespan lamp) or <16 months
ago (BA7532 long lifespan lamp), the High Integration Period warning is likely due to
dirty cell windows. Refer to Section 7.5 for cleaning / replacement procedure. Do not
reinstall the fibres at the measurement cell at this time. However, if the integration
period is >100 milliseconds OR the shape of indicated spectrum is significantly different
from the factory reference spectrum, it will be necessary to test the fibres individually.
Continue to Step 12.
12. Disconnect the fibre optic cables from the UV Lamp enclosure and the spectrometer
by unscrewing the nuts and pulling the fibre optic cables out.
13. Connect one cable directly from the UV lamp enclosure to the spectrometer. Repeat
steps 9 and 10 for this cable. Observe the integration time and the shape of the
spectrum. If the integration time <50 milliseconds AND the peak shape is similar to the
factory reference, the cable is good and does not require replacement. If the integration
time >100 milliseconds OR the peak shape is significantly different from the factory
reference spectrum, the cable should be replaced.
14. Repeat step 13 for the other fibre optic cable.
15. If both fibre optic cables are found to be good, and the UV lamp was last replaced <6
months ago, the
High Integration Period
warning is likely due to dirty measurement
cell windows. Refer to Section 7.5 for cleaning / replacement procedure. If at least one
cable is found to require replacement, obtain the necessary replacement(s) and then
continue with this procedure.
16. Reinstall both fibre optic cables as described in Section 2.4.5.
17. Connect the short fibre to the SMA fitting on the top of the measurement cell. Connect
the long fibre to the SMA fitting on the bottom of the measurement cell. Hand tighten
the nuts.
18. Loosen the set screw holding the SMA Fittings into the measurement cell slightly so
that the SMA fitting can rotate and slide in and out.
19. Use the F2 / F1 keys to navigate to the Spectrum panel. Adjust the position of each
SMA fitting in the measurement cell by rotating it slightly left and right and sliding it in
and out to find the position that gives the greatest Peak Height . Once the optimal
position is found for each fibre, re-tighten the set screw.
The SMA connectors only need to be finger-tight. Do not overtighten the
connectors as this may damage the cable.
20. Optimize the integration period by using the F4 / F3 keys to highlight Optimize Integ.
Time
, then press

.
21. Observe the optimized integration time. If the High Integration Period warning has
cleared, no further work is required at this time. Proceed to the next step in this
procedure. If the
High Integration Period
warning is still present, however, it is likely
that the cell windows are dirty and/or damaged. Proceed to Section 7.5.
