The  instrument  will  automatically  re-align  the  monochromator  using  spectral  peaks  associated  with 

the  xenon  flash  lamp.  During  this  initialisation,  the  instrument  displays  CAL  on  the  primary  display 

before  displaying  the  main  measurement  screen.  Please  note  that  the  instrument  will  go  to  the  last 

wavelength and measurement mode used.
