Opening the Main Cover
To perform most maintenance tasks, you have to open the main cover of the spectrometer.
WARNING
Switch off the mains power supply to the spectrometer, wait 60 seconds

an instrument fitted with KBr optics.
The humidity sensitive optics will be damaged if subjected to a relative
humidity in excess of the specified level.
