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

Do not attempt to separate the Laser from the power supply. The Laser

retains an electrical charge even when the main power is switched off.

Open the main cover of the instrument as detailed on page 80 and identify the laser

and the laser power supply.
