To adjust the
enter the new values, separated by a comma, e.g. 100,80,60. The values represent the
factor in % for (Mo/Mo, Mo/Rh, W/Rh).
Three settings, e.g. try (short-term, is valid for one measurement only), save (long-term,
valid also after reboot) and load (effective, valid until the system is rebooted) can be used
in the drop-down menu above the values.
To change the values permanently, enter the correct values and select save, then use
load to load them before you start another exposure.

NewScalingValue = OldScalingValue * DoseValue

--> Calculation of the new Mo/Rh, W/Rh dose scaling values:
NewScalingValue = OldScalingValue * PixelValue
--> Proceed as follows:
1. Call up the service software and select:
Acquisition System -> BRICK Configuration
The BRICK service software opens another window.
2. Select Brick -> AEC Configuration.
3. The BRICK software switches to a higher user level, thus a Username and Password
have to be entered.
