10 Storing and recalling data
The FUSION processor system has powerful and flexible features for storing and recalling 
calibration data. When a calibration is stored, the user can recall all calibration parameters at 
any given time or on any given control PC. Calibration can be stored:
•	In the multi image processor unit
•	On the control PC. This is a copy of the data stored in the multi image processor unit
•	Both
When a calibration has been completed, the calibration must be accepted \
in the menu.  
Accepting a calibration means the binary data is stored in the unit and will be used  
automatically when the unit is powered on. 
10.1 Storing/recalling calibration to/from the FUSION unit
When storing calibration to the FUSION unit, it will be saved in the int\
ernal memory of the 
unit. Should the multi image processor unit or the control PC lose power during calibration, 
the data can easily be recalled. To save the calibration to the multi image processor unit click 
“Save Calibration” in the Calibration view toolbar, press Ctrl+S or select “Save Calibration” 
from the file menu (Figure 10-1). Any calibration already stored in the multi image processor 
unit will be overwritten.
 
Figure 10-1.  Save current calibration to the FUSION unit
If you want to recall your last saved calibration, click “Load Calibration” in the\
 Calibration view 
toolbar (Figure 5-11).

10.2 Storing/recalling data to/from the control PC
Before you can save a calibration to the control PC, you first have to save your calibration 
to multi image processor unit. When performing a backup to the control PC, the last data 
stored in the multi image processor unit will be copied to the control PC. To backup your 
data, select “Backup Calibration files..” from the file menu (Figure 10-3). The window in Figure 
10-3 will appear.
