5. Open the oven cabinet door and remove the black cover on the oven enclosure.
The oven enclosure and all of its components are HOT (
150°C
). Wear
appropriate personal protective equipment (gloves, eye wear, clothing etc)
if working with hot surfaces or wait until surface have cooled to safe
temperatures before performing maintenance tasks.
6. Disconnect the fibres from both the top right and the bottom right of the measurement
cell block by unscrewing the nut and pulling out.
7. Joint the two loose ends of the optical fibres together by cutting the end off of one of
the orange fibre caps and connecting both fibres into the same cap. Press the fibres
into the cap so that both ends are in contact with one another.
8. Using the F2 / F1 keys on the keypad, navigate to the
Spectrum
panel.
9. Use the F4 / F3 keys to select
Optimize Integ. Time
and press
↵
to optimize the
integration period. It may be necessary to press
↵
more than once to get a peak height
≈28000 A/D counts.
10. Use the F4 / F3 keys to select
Show Factory Reference
and press
↵
to display the
factory reference spectrum.
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 <6 months ago, 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
