AEC MAS Balance Verification
The generator AEC mAs balance was pre-calibrated at the factory. However,

verification of AEC mAs balance assures AEC calibration accuracy. When bal-

anced, the mAs at the specified exposures will be approximately the same

(±6%). This procedure only needs to be performed once prior to AEC cali-

bration of the film/screen combination(s) used with the system. Proceed as

follows:
1. If not already done so, connect a kVp bleeder tank in series between

tube and High-Voltage (H.V.) Transformer A17. If using a mAs meter,

connect the mAs meter between pins A17P1-9 and A17P1-10 on H.V.

Transformer A17. This connection is made by removing the two green/

yellow wires connecting A17P1-9 and A17P1-10 to the ground stud on

top of the H.V. Transformer (see Figure B-22) and connecting the

removed wires to the mAs meter. (Note: These wires must be re-con-

nected when finished calibration.)

2. Place 20 cm of acrylic in the X-ray beam. (Where practical, adjust acrylic

thickness to obtain approximately 100 millisecond exposures.)

3. If calibrating a" level" type ion chamber, ensure all three ion chamber

detectors are selected.

4. Press the Manual/AEC Mode button on the operator control panel and

select enter AEC mode.

5. Set the operator control panel for 110 kVp (100 kVp if calibrating a "level"

type (Siemens) ion chamber - requires AY40-027S AEC board), 75S mA

and take an exposure.

6. On the Dynalyzer Digital Display or mAs meter, note the measured mAs

value.

7. Set the operator control panel for 110 kVp (100 kVp if calibrating a "level"

type (Siemens) ion chamber - requires AY40-027S AEC board) and the

highest available mA station. Take an exposure.

8. On the Dynalyzer Digital Display or mAs meter, note the measured mAs

value.

9. The mAs values noted must be within ±5%. If not, adjustment of the

dV/dt potentiometer on AEC Board A11 is necessary:

•

If the generator is equipped with "standard" type AEC (i.e., AEC

Board A11 is part number AY40-031S), adjust potentiometer A11R12

to increase or decrease the mAs value.
