1.10 Checking the adjustment
Rotate the head support to the 0° position and place the two ear posts into their holders if they
are not already installed.
Embedded in the end of the left (L) ear post there is a metal ball and embedded in the end of
the right ear post (R) is a metal ring. The images of these that appear on an exposed image
are used to check the alignment of the ear posts.
Take a beam check exposure. Refer to the Planmeca Device Tool manual, publication num-
ber 10031558.
On the image you will see the images of a metal ball and a metal ring. They must be concen-
tric, or if not exactly concentric there must be a small gap between the edge of the ball and
the inner edge of the circle.
Figure 24
If the ball touches the ring the ear posts must be adjusted, refer to section 1.7 “Cephalostat
head support adjustments” on page I-11.
