7.2 Checking the mechanical system adjustment
Checking the mechanical system adjustment
1. Insert the constancy test phantom in the bite block holder of the unit.
2. Measure distances B1, B2and B3 between the tube assembly
housing and measuring point M on the constancy test phantom
(positions 1, 2 and 3) using the steel tape measure from the service
set.
3. Then calculate the ideal distance between the tube assembly and
measuring point M as follows: (B1+B2)/2 = ideal distance
4. Distances B1, B2 and B3 must not deviate more than ± 2 mm from
the calculated ideal distance. With deviations exceeding ± 2 mm, the
unit must be adjusted mechanically via the position of the ring
motor [ → 193].
