Installing Filters in the Filter Wheel
The following procedure describes how to install a filter in the filter wheel. The same
procedure should be followed when replacing a filter or the methane cell.
The filter wheel assembly is removed from its mounting and placed on the standard sample
slide baseplate. It therefore may be necessary to remove the sample slide.
WARNING
Switch off the mains 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.
1. Set the Filter Wheel to Position 1 on the Setup Instrument BeamPath tab in Spectrum
software.
Position 1 will be labelled as
None 15000 – 0 cm
-1
and be the first option in the
drop-down list.
2. Open the main cover of the instrument as detailed on page 80 and identify the filter
wheel (Figure 51).
