If the deviation is greater, loosen the 4 Allen screws (arrow/Fig. 7/Fig. 8) and shift the
collimator correspondingly.
Then tighten the screws on the collimator (arrow/Fig. 7/Fig. 8) again.
•
Repeat the test procedure and readjust the collimator until the light and radiation field lies
inside the permissible tolerance (< 1.6 cm).
Checking the exposure switch-off
•
Check the exposure switch-off in the following settings:
40 kV, 200 mAs (max. mA)
100 kV, 80 mAs (min. mA)
To do
this:
NOTE
POLYMOBIL III
Release exposure. The radiation indicator (10/Fig. 4) lights up.
The exposure must switch off after 5 s + 3.5 s.
The radiation indicator goes out, the acoustic signal stops.
The exposure time depends on the level of the line voltage and
the quality of the mains.
