shall not overshoot too high. The proper mA waveform is as shown Fig.8-2 below,
otherwise adjust the filament value at “40kV,20mA”. If the mA rise time is too long,
the filament value shall be increased, and if the overshoot is too high, the filament
value shall be decreased. The number of filament values being adjusted each time
shall not exceed 3. Save and return to the main screen for exposure till the mA
waveform is normal.

5) Change the filament value determined in 4) to 20mA, and the steps of 45kV, 55kV,
65kV...125kV.
6) Set the tube current to 10mA, 12.5mA, 16mA, 25mA,...100mA respectively, and keep
the exposure time for 100ms. Test at 40kV according to step 4), and set the values of
other tube voltages according to step 5)
Caution: The number of filament values being adjusted each time shall not exceed 3.
8.5 Quality Assurance
The following quality control inspections shall be trained and provided service by
SIUI qualified engineers.
a) The device has no cosmetic damage. The connection surface of the whole device
enclosure is flat; the silk screen pattern is clear, positioned properly, and there is no
oil stain. The buttons operate normally, and the opening and closing of the
collimator shall be easy, flexible and reliable.
b) The labeling and signs are complete and compliant, positioned properly, and the
