PROGRAMMING THE EXPOSURE VALUES
Programming the density values
40 Planmeca Intra X-ray Unit
Press the SELECT key briefly, the mA display will start to
flash and the kV value is stored in the memory.
The mA value can now be changed with the parameter
adjustment keys.
In the film-based imaging mode the type of the film
processor, processing chemicals and temperatures used
will affect the film density.
By changing the density value all the preprogrammed
values can be changed. This can be used for example
when a more sensitive or less sensitive film is being used
or when the cone is being changed.
Changing the density value will change the selected time
value as follows: one density step equals to one time step.
The negative density value shortens the selected time
value, whereas the positive value lengthens it.
When the SELECT key is pressed a third time briefly, the
current density value starts to flash on the time display
and the mA value is stored in the memory.
The imaging mode can be changed by pressing the
MODE key briefly.
The density value can now be changed with the
parameter adjustment keys. Note that the density value
will affect the time value both in adult and in child mode.
The density has 11 steps from -5 (light exposures) to +5
(dark exposures).
Select the child/adult mode and program its settings as
described above or exit the programming mode by
OR
pressing and holding down the SELECT key. The density
value is stored in the memory.
