8. The large filament calibration screen is displayed. Note the "Filament
Small" button is now yellow to indicate small filament calibration is com-
plete.
9. Take an exposure at the setting indicated on the Filament Calibration
Screen (i.e., 70 kVp, 300L mA, 15 msec).
If using an oscilloscope, set
time to 50 msec
.
10. On the Dynalyzer Digital Display or mAs meter, observe the measured
current value. (Ideally, this value should be 300 mA or 4.5 mAs.)
11. If not 300 mA, or if waveform is not flat, press the large filament offset
value button (located directly below "Filament Large" label). To increase
mA, raise the filament offset value; to decrease mA, lower the filament
offset value.
12. Re-take exposure at same settings and adjust large filament offset value
if necessary. Repeat this step until measured mA is 300 or when wave-
form is sufficiently flat. If so, filament calibration is complete.
13. To proceed to mA calibration, press the Next button.
Note: An error message appears if the filament
current is set too low, which indicates the fila-
ment offset value for the filament being cali-
brated is set too low or high. If this occurs,
increase or decrease the filament current.
