of  the  Operator‟s  Manual  and  intended  to  quickly  familiarize  you  with  making  basic  leaf  gas  exchange 
measurements.  IF YOU HAVE NOT YET READ AND WORKED THROUGH THE TUTORIAL PLEASE 
DO SO NOW, BEFORE CONTINUING.

The  Operator‟s  Manual  is  designed  to  guide  you  through  the  various  menus,  displays  and  operational 
features of CIRAS-2.  Each CIRAS-2 system is supplied with two versions of the remote control software 
program (RCS): i) Windows CE (pre-installed on the UI and earlier PC-Pencentra) and ii) full Windows 
version (for lab PC or notebook computer) on CD ROM.  The Windows CE version of RCS comes pre-
installed on the UI with a back-up copy supplied on a  Flash Card.  All of the menus and displays are 
identical in both versions of CIRAS-2 RCS.  Please note: due to file sizes and availability of space, Help 
Files are not available on the UI. 
 
We recommend that you install the Windows software to your lab computer upon receipt of your system.  
We also recommend that you first become familiar with the operation of your system using your PC or 
notebook, taking advantage of the viewing ability and convenience of the computer.  It is a good idea to 
take a few moments to review the ReadMe.txt file contained in the root directory on the CD ROM supplied.  
This file contains important information relating to the installation of the CIRAS-2 remote control program.
