Cooling Time 

“Cooling Time” is the user defined maximum time for the vessel to cool prior to removal. The default cooling time is 20 
minutes. The “Cooling Time” cannot be edited/changed when creating a new method. The cooling time default that 
created in the “User Profile” is the maximum time used when cooling a reaction. Should the reaction reach the pre-
determined release limits prior to the cooling time, the cooling stage will stop. 
1.  Use the “+/-” keys to highlight “Cooling Time.” 
2.  Press the ENTER key. 
3.  Use the “+/-” keys to change the cooling time from 0-60 minutes. 
4.  Press the ENTER key to accept the cooling time. 
 

Backup Methods 

“Back Up Methods” backs up the methods of the current user. These methods can be transferred to another instrument or 
placed on a personal computer. 
1.  Install a CEM supplied USB flash drive into the right side of the Discover system. 
2.  Use the “+/-” keys to highlight “Backup Methods.” 
3.  Press the ENTER key. If a USB flash drive is installed in the USB port, a screen appears indicating the percentage of 

the files backed up on the USB flash drive. Once all user methods are backed up, the software returns to the User 
Setup screen. 

 

NOTE: 

If a USB flash drive is not installed in one of the USB ports, the software will prompt the user to install a USB flash 

drive. If desired, press the “Home” key to exit the screen. 

 

CAUTION 

 

Do not remove the USB flash drive from the USB port during method backup or restoration. Removal of the USB 
flash drive prior to completion of method backup or restoration will corrupt the data on the USB flash drive 
and/or the system files. Wait 15 - 20 seconds after the completion of method backup or restoration prior to 
removal of the USB flash drive. 

 

Restore Methods 

“Restore Methods” transfers “backed up” methods and information from the USB flash drive to the system file. 
1.  Install a CEM supplied USB flash drive into the right side of the Discover system. 
2.  Use the “+/-” keys to highlight “Restore Methods.” 
3.  Press the ENTER key. If a USB flash drive is installed, a screen appears indicating the percentage of the methods 

restored on the USB flash drive. Once all methods are restored, the software returns to the User Setup screen. 

 

NOTE: 

If a USB flash drive is not installed in one of the USB ports, the software will prompt the user to install a USB 

flash drive as indicated above. 
 

Calibration Setup 

The “Calibration Setup” page is the 2

nd

  page that appears after selecting “System Setup” from the “Discover Home” 

screen. This screen allows the user to calibrate or enter a calibration value for the temperature and pressure controls.
