4 Generator Calibration
CALIBRATION TIPS
1. At all times the Dynalyzer digital readout should equal the readout on the left
monitor of the Workstation.
2. During calibration of the .3 mm and .6 mm focal spots, the duty cycle should never
reach 1225.
3. All shots of less than 1 mA are rejected.
4. The system should not take more than eight shots to achieve 1 mA.
5. The 0.3 mm focal spot calibration should follow these guidelines:
A. 40 kV, mA≅45 With each increment of 25 for duty cycle mA
should increment by 2 to 3.
B. 60 kV, mA≅50 With each increment of 25 for duty cycle mA
should increment by 3 to 4.
C. 80 kV, mA≅50 With each increment of 25 for duty cycle mA
should increment by 3.
D. 100 kV, mA≅40 With each increment of 25 for duty cycle mA
should increment by 3.
E. 120 kV, mA≅33.3 With each increment of 25 for duty cycle mA
should increment by 3.
6. The 0.6 mm focal spot calibration should follow these guidelines;
A. 50 kV, mA≅75 With each increment of 25 for duty cycle mA should
increment by 8.
B. 60 kV, mA≅66.7 With each increment of 25 for duty cycle mA should
increment by 8 or 9.
C. 80 kV, mA≅50 With each increment of 25 for duty cycle mA should
increment by 8 or 9.
D. 100 kV, mA≅40 With each increment of 25 for duty cycle mA should
increment by 9 or 10.
7. During the verification run, shots will have a duration of 1500 mS. If the batteries are
weak this is where they will cave in.
8. At the end of the calibration, the duty cycle, calibration coefficients and the
verification data are merged to create the ALL.DAT file.
9. Before sending the generator diskette to OEC for archiving make sure that the
following files were created in the following order:
