System Manual
There are 2 methods to set the dose rates.
•
Automatic dose rate adjustment: with this method the dose rate
needs only to be set for the DR operating mode and dose rate
level HIGH in the full format. All other dose rate levels and the
necessary TV iris diaphragm values are automatically calculated
and stored.
After the automatic dose rate adjustment, perform
"Calibrating the TV iris diaphragm for automatic iris diaphragm
regulation (AIR)", Chapter 5.
Then all dose rate values must be checked according to
"Checking the set dose or dose rate", Chapter 5. If the dose or
dose rate values deviate from the nominal values by more than
the permissible tolerance, the dose rate adjustment must be
repeated according to "Manual dose rate adjustment" of
Chapter 5.
•
Manual dose rate adjustment: with this method about 40 dose
rate values must be set for the different operating modes.
Use this method only if automatic dose rate adjustment is not
successful.
