13. If using an oscilloscope, select Scope radio button (Step 1.); if using a
mAs meter, select Mas Meter.
14. Take an exposure at the setting indicated on the Filament Calibration
Screen (i.e., 70 kVp, 300L mA (250 mA if Model QG-200-SE generator),
15 msec).
If using an oscilloscope, set time to 125 msec .
15. If using an oscilloscope, observe the large filament current pulse wave-
form for "flatness" (see Figure D-18). If using a mAs meter, observe the
measured mA value. Ideally, the mA value appearing in the Large Fila-
ment Calibration Screen (Step 1.) will match the reading on the mAs
meter within allowable tolerance.
16. Press the Calibrate button.
17. If waveform is acceptable or if mA reading is within tolerance, press the
Confirm button. The calibration value is saved and the system advances
to the next calibration procedure.
