AUTOMATIC EXPOSURE CONTROL (AEC) CALIBRATION
Technical Manual
After adjustment three test exposures should be taken from the AEC calibration tool as fol-
lows. Enter to the
Main display. Switch the AEC function on and make sure that the AEC
optical density value 0 (refer to the user’s manual). Select average jaw size.
1) First exposure: Do not change the kV and mA values. Take an exposure. Check in the
Main display that the kV and mA values are not changed during the exposure.
2) Second exposure: Increase mA value by 5mA from the original value. Take an exposure
and after the exposure check in the Main display that the kV and mA values have been
decreased.
3) Third exposure: reduce mA value by 2mA from the original value. Take an exposure and
after the exposure check in the Main display that the kV and mA values have been
increased.
If the kV and mA values are not correctly adjusted during the exposure, perform the
AEC calibration again.
Remove the AEC calibration tool and attach the removed covers.
