7. Set the kVp and mA techniques to the desired values using the up/
down arrow buttons, then press the Proceed button. The Filament
Point Adjustment Tab displays:

8. Take an exposure.
9. Press the Calibrate button.
10. Observe the filament offset waveform captured on the oscilloscope.
It should look similar to waveforms shown on the Advanced Filament
Calibration Intro 3 (Waveforms) Tab.
11. If the waveform is correct, either press the Next Point button to
select another technique to calibrate, or press the Complete button
to exit Advanced Filament Calibration.
12. If the waveform is not correct (i.e., Too High or Too Low as shown on
Advanced Filament Calibration Intro 3 (Waveforms) Tab), the fila-
ment preheat value must be adjusted using the slider control shown
in Step 1 of the Filament Point Adjustment screen (see Figure D-25).
If waveform is Too Low, increase the filament preheat value by mov-
