L. EXTRACTING DATA (Refer to Figure 16) 

Each measurement run is stored as a file within the CEL-62X in a .CSV format.  This 
format will automatically open with MS EXCEL or similar office applications. The files are 
named consecutively from 1 to 100, so the first run will be named R001.CSV.  All 
measurement parameters are contained within these files, regardless of the displayed 
parameters selected within the instrument setup. 

The CEL-62X acts as a removable storage device when connected to a PC by the 
CMC51 cable.  See Figure 18 for the location of the USB connection on the CEL-62X 
Series.  Once connected, the PC will automatically detect the instrument is connected 
and within a few seconds have installed the necessary drivers.  An Explorer window will 
open on the PC to show the files on the instrument.  Simply copy the files to your PC as 
required.
