Chromatogram saving 

        

      Storage of chromatograms on the internal hard drive is configured from the 

HISTORIC-CHROMATOGRAM

 menu. To enable this feature, the check 

box must be selected. (See Figure 45) and the chromatograms will be saved at 
the end of each cycle.  If not selected, the chromatogram will not be saved.  

 

 

 

Figure 45 : Historic-Chromatogram saving menu 

 

A space of 500 Mb is configured on the hard drive. This will allow storage of 
around one month of continuous data, depending on the complexity of the 
analysis. When the stored data reaches 99% capacity, the new data will over-
write the files, starting with the oldest.  
 
To transfer the data, insert a USB key into the port at the front of the analyser 
and press the 

Transfer to USB stick

 button. All the stored data will be 

transferred to the USB key. If the USB key is not detected, an error message will 
be displayed.  
 
Chromatograms are transferred to a folder on the USB named 

“chrom_X

X

XXX” where XX

XXX is the serial number of the analyser. Copy 

the folders onto a PC computer and use the import feature of Report Software to 
import them.  
 
Chromatograms on the hard drive can be deleted by pressing the 

Delete

 button. 

This will delete all chromatograms on the hard drive. The progress bar indicates 
the actual used space on the hard drive.
