SECTION 7  –  Spectrum

The  spectrum  measurement  mode  enables  measurements  of  absorbance  or  %  transmittance  over  a 
range  of  wavelengths  to  be  performed.  The  absorbance  or  %  transmittance  at  each  wavelength  is 
plotted graphically. Post measurement tools such as peaks and valleys analysis and spectral points analysis 
can be performed. This operating mode can be used to partially characterise a sample. 

7.1 

MODE SPECIFIC PARAMETERS

The spectrum minimal operating menu enables baseline 
scans  and  spectrum  scans  to  be  performed  without 
changing  any  measurement  parameters  or  settings. 
Pressing  the  key  adjacent  to  the 

JW

  icon  opens  the 

expanded operating menu.

The  spectrum  expanded  operating  menu  enables 
measurement  parameters  to  be  changed.  The  utility 
toolbar on the left hand side of the screen enables access 
to  printing,  print  setup  options,  results,  methods  and 
autologging  options.  For  more  details  on  the  different 
functions of the utility toolbar refer to section 10.  

The 

scan settings

 icon enables the graph y-axis, absorbance or % transmittance operating mode, start 

and end wavelengths and scan interval to be set. The 

peaks and valleys threshold 

icon enables the 

peaks and valleys threshold to be set. The 

peaks and valleys table

 icon enables the peaks and valleys of 

the scan to be viewed in tabular form. The 

spectral points analysis

 icon enables points to be selected 

from the scan for post measurement analysis.
