9.2 Preprogrammed settings values
NOTE Two sets of exposure values (time/kV) have been pro-
grammed for each exposure region: one for adult
mode and one for child mode.
NOTE The exposure values are programmed corresponding
the normal mode density value 0 (factory preset va-
lue).
NOTE In the digital imaging mode the exposure time values
are automatically scaled according to the density va-
lue used in digital imaging mode. The factory preset
density value in the digital imaging mode is -4.
These values can be programmed by the user, see sec-
tion 10.2 “Programming the preprogrammed settings”
on page20. The recommended exposure values are gi-
ven in section 12 “EXPOSURE VALUE TABLES” on
page 23.
Changing the density value will change the selected ti-
me value as follows: one density step equals to one ti-
me step. The negative density value shortens the selec-
ted time value, whereas the positive value lengthens it.
NOTE These values are for speed D films (Kodak Ultra-
speed) and for digital imaging. For the speed E films
(Kodak Ektaspeed) select three steps shorter exposu-
re time, and for the speed F films (Kodak Insight) fi-
ve steps shorter exposure time.
When using the 30 cm long cone program the values
according to the table given in section 12 “EXPO-
SURE VALUE TABLES” on page 23.
