PROMAX 3D: ADJUSTMENTS & CALIBRATIONS
Place the beam alignment tool on the sensor head alignment tool upside down as shown in
Fig. 80. Slide the beam alignment tool as down as it goes.

Figure 80
Darken the room sufficiently so that you will be able to see the image of the radiation beam on
the beam alignment tool (it is fluorescent and glows when the radiation beam strikes it), but
not so dark that you cannot see the lines of the alignment rectangle.
Protect yourself from radiation and press the exposure button. The beam image appears on
the alignment tool. Observe the beam from behind the tube head.
CAUTION Radiation is generated when the exposure button is pressed. Take
adequate protection measures. Keep the exposure time as short as
possible.
X-ray units with 3D sensor V1:
The radiation beam must reach but not overlap the lines marked on the beam alignment
tool (shown with arrows in the figure above).
X-ray units with 3D sensor V2 / 3D s sensor:
The radiation beam must overlap the upper line marked on the beam alignment tool by 10
mm and reach the lower line marked on the beam alignment tool (both lines shown with
arrows in the figure above).
