3.
Make a master adjustment of mA leading edge for Small focal spot.
Select 50 kVp, 50 milliseconds, and 100 mA on Small focal spot. Make an
exposure. If adjustment is needed, press the MASTER mA button and increment or
decrement the value for SM F.S. that appears in the lower left corner of the screen
as shown below and SAVE the change. Press the BACK button to return to the
exposure screen. Repeat as needed to achieve the proper mA amplitude and mAs.
4.
Make a master adjustment of mA leading edge for Large focal spot.
Initially select 50 kVp, 50 milliseconds and 200 mA. If adjustment is needed, press
the MASTER mA button and increment or decrement the value for LG F.S. that
appears in the lower left corner of the screen as shown below and SAVE the
change. Press the BACK button to return to the exposure screen. Repeat as
needed to achieve the proper mA amplitude and mAs.
Using the same kVp and time, now select 300 mA and verify mA output. If
adjustment of mA leading edge is needed at 300 mA, press the MASTER mA
button, change the LG F.S. number and SAVE as before. Press the BACK button
and repeat as needed to achieve the desired mA amplitude and mAs.
5.
Set mA feedback (stabilized mA level) for Small and Large focal spot.
On the System Controller board set DIP1-4 to ON (right ) to enable mA feedback.
This switch will remain in this position for the remainder of calibration and during
normal use.
