AEC calibration.
The AEC Calibration menu provides access to the system's various AEC
calibration functions, briefly described as follows:
• Film Screen/Combination Selection Key - Selects the film/
screen combination you want to calibrate (system default
choices are Wall 72", Wall 40", Table 40", 100 Speed, 200
Speed, 800 Speed, Film/Screen 7, and DIGITAL (if "Digital
Receptor" is enabled in the Service Configuration Menu)
• AEC OD Calibration - Calibrates the optical density for the
currently selected film/screen and ion chamber combination
• Reciprocity Calibration - Calibrates the reciprocity failure law
correction factor for the currently selected film/screen and ion
chamber combination
• AEC KV Calibration - Calibrates the tube voltage settings used
in conjunction with the currently selected film/screen and ion
chamber combination
• Main - Returns to the Service Calibration Menu (see Figure
3-27)
• Copy Film/Screen - Accesses the Copy Film/Screen Menu. The
Copy Film/Screen Menu is a utility that enables AEC calibration
data to be copied from one calibrated film/screen combination
