1. Test overview.
This test is used to adjust the film carrier so that a RGB image is of the same size as of the IR image.The scanner will scan a B&W film in RGB and in IR, will determine the size of each image and will calculate the ratio of it. A ratio of 1 means that the 2 images are exactly of the same size.
ReBrand: the size of the image is according to the distance of the CCD Film. The size can be changed by slightly pulling in and out the film carrier in the scanner, so that the measurement in RGB is done at the same level as of the IR measurement.
2. Test conditions.
This test relates to the Mounted slide gate inserted in the scanner.The Mounted slide gate must be inserted in the scanner to carry out this test.
A B&W Slide must be used for this test (ref. 070 100 319A):
No parameter is saved.
3. Pre-requirements.
- CCD IR Test is accepted to ensure that the measurement of the IR signal is correct.
- Slide Cal Position Autofocus Test is accepted to ensure that the position of Slide EncoderAF is correct.
- Slide Cal V-Offset test is accepted to ensure that Voffset is correct.
4. Test realisation.
Click on RUN to execute the test. A window will come up requiring the insertion of the B&W slide. When the slide is inserted. (Caution: Watch for the direction of the film), click on OK.The scanner will scan the slide in RGB and in IR then will automatically detect crosses present on the film to calculate the size of each image (see Automatic Crosses Detection for more information on this subject).
When this is done, the ratio will be displayed and the test will be accepted or rejected accordingly.
5. Test acceptance.
The test is accepted if the ratio (IR image size / RGB image size) lies between 0,9990 and 1,0010.6. Other affected tests.
If the ratio is outside the tolerances, the following tests will be affected:- Slide Cal encoder 2.
- Slide Cal RGB-IR.
- Slide ADDR.
7. Trouble shooting.
