7. Press the key next to the First Cal field to save the first (50 kVp,
400L mA) reciprocity calibration point entry. The Reciprocity Calibra-
tion screen is updated for the middle reciprocity calibration point.
8. Place a film cassette in the tray. Take an exposure at the setting indi-
cated in the center display box (i.e., 50 kVp, 75S mA).
9. Press the up or down key located next to the Measured OD field
until the optical density value displayed equals the measured optical
density value.
10. Press the key next to the Middle Cal field to save the middle (50
kVp, 75S mA) reciprocity calibration point entry. The Reciprocity Cal-
ibration screen is updated for the final reciprocity calibration point.
11. Place a film cassette in the tray. Take an exposure at the setting indi-
cated in the center display box (i.e., 50 kVp, 25S mA).
12. Press the up or down key located next to the Measured OD field
until the optical density value displayed equals the measured optical
density value.
13. Press the key next to the Save Calibrate field to save the calibration
data for the 50 kVp, 25S mA reciprocity calibration point.
14. Press the key next to the Next Calibrate field.
