Replacing the Laser and Power Supply
WARNING
Switch off the main power supply to the spectrometer, wait
60 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.
WARNING

retains an electrical charge even when the main power is switched off.
1. Open the main cover of the instrument as detailed on page 70 and identify the laser
and laser power supply (Figure 52).
