- 17 - 
Open  the  „Accessory‟ drop  down  list  containing  the  standard  cuvettes and chambers that may be used 
with CIRAS-2.   From  this  list  select  „PLC6 (U)  18  mm  diameter  insert‟   – this is the most common leaf 
cuvette used with the CIRAS-2 system.  By making this selection, various other options will automatically 
be set to default  settings  that  are  standardized for  the PLC6  (U)  cuvette.   In  the  „Light  Type‟ list select 
„LED‟.  If using a different insert with the PLC6(U) or a different cuvette, select the appropriate option from 
the list.  Click OK.  The Settings dialog and all of its options will be described in detail later.

While working with CIRAS-2 from your PC or notebook you have access to compiled Windows Help Files 
through the  ?  buttons associated with most CIRAS-2 screens and dialog boxes.  Help Files are context-
sensitive, providing detailed information about the screen or user option you are currently viewing.   
 
PP Systems is continuously updating our print and on-line documentation to reflect hardware and software 
changes.  Due to this some images and information contained in compiled Windows Help Files are out of 
date and may not reflect exactly the current version 1.07 RCS software.  Always consult the print version 
of  the  Operator‟s  Manual  first  before  using  the  on-line  resource.    Please  note: Help  Files  are  not 
available with the Windows CE version of RCS used with the UI.
