seconds and disconnect the power cable before you open the cover of
the spectrometer. This makes sure that you are safe from electrical
shock and laser radiation.

source to cool before attempting to remove it.
1. Open the main cover of the instrument as detailed on page 84 and identify the
Source (Figure 34).
