3. Select Next to proceed to mA Calibration Intro 2 screen, or you may
select a particular mA Calibration to perform by selecting its correspond-
ing tab (choices are Low mA and High mA). For this example, "Low mA"
is selected, as shown below:
Figure D-28. Sample mA Calibration Screen (Low mA is shown)
4. If not already done so, a kVp bleeder tank should be connected 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 D-21) and connecting the
removed wires to the mAs meter. (Note: The MAS meter should remain
connected throughout calibration. These wires must be re-connected
when finished calibration.)
5. Take an exposure at the setting indicated on the Low mA Calibration
Screen (i.e., 60 kVp, 75s mA, 100 msec).
