Planmeca Proline XC X-ray unit  D-39

AUTOMATIC EXPOSURE CONTROL (AEC) CALIBRATION

Technical Manual

6.3 Adjusting the AEC-signals

NOTE

Take five 10 seconds exposures in the service settings mode with a kilovolt value of 68
and a milliampere value of 7 before adjusting the AEC-signals. 

Enter the service settings mode. From the list of service settings select Test exposure.

Figure 67

The display shown below appears. Switch ON the AEC by touching the 

AEC

 field.
