Calibrating and adjusting the AEC
Sensitivity correction (fine setting)
11
When all desired object table groups are calibrated, a fine setting of the sensitivity correc-
tion should be performed for all available object tables.
1. In <Mainmenu> select <Configuration>, <AEC> and <Sensitivity correction>.
2. Install an object table.
3. Insert the reference cassette, with a new film, in the object table.
4. Select <F3> for support and perform an exposure.
5. Remove the exposed film, make a sensitometer strip and develop the film.
Measure O.D. in the measuring point and correct the value according to
"Correction of the measured Optical Density (O.D.)" on Page 11 - 7 .
6. If the value differs from 1.5 O.D. (or by customer preferred) adjust the values in
dialog
AEC - Sensitivity correction
(Fig. 7). Repeat the procedure described in
steps 2 to 6. Save with <F2>.
7. Repeat this procedure for the other object tables if applicable.
Make sure the backup floppy is inserted.
From this point on a compression plate may be used.
