3D.5.0 AEC DENSITY CALIBRATION (Cont)
Step Action
10.
Select the next density step (i.e.
- 4
) and enter the appropriate calibration number for that step. Then repeat steps 7 and 8.
11.
Repeat the previous step for each remaining density minus step.

Determine the highest density plus step to
be used. If there will be unused density
steps, i.e.
+8
,
+7
,
+6
, these density steps
must be disabled by setting them to
--
.
This is done by using the
–
button to scroll
down until the

13.
Select the highest density plus step that
will be used, i.e.
+5
. Use the
+
or
–
buttons to set the calibration number for
that step to the desired relative density
value (example
99,
this will give
approximately double the density).
For the highest density plus step that will
be used, i.e.
+5
, enter the desired relative
density value (example
99,
this will give
approximately double the density).
For the highest density plus step that will
be used, i.e.
+5
, enter the desired relative
density value (example
99,
this will give
approximately double the density).
14.
Make an exposure and confirm that the measured mAs is approximately the desired value.
15.
If the measured mAs is not as expected, adjust the calibration number and repeat the previous step.
16.
Select the next lowest density step (i.e.
+4
) and enter the appropriate calibration number for that step. Then repeat steps 14 and 15.
17.
Repeat the previous step for each remaining density plus step.
