limitations
An automatic system limits the opening of x-ray beam regarding
the detector format and the focus /film distance.
To check the correct functioning of this system, proceed as follow:
Press the button « Preparation (1
st
trigger) control », the collimator
shutters are opened to the detector format
Keep the button held down
Check that the light field corresponds with the detector format
(± 0.5 cm) by switching on the light beam and that must
correspond whatever the focus /film distance is, from 110 cm to
180 cm
This automatic system limits the opening of x-ray beam to the
maximum of detector format. Therefore, it is recommanded to use
the smaller possible x-ray field, closing the collimator shutters with
the proper control joysticks.
Monthly
Preventive maintenance visits (refer to chapter « preventive maintenance » of service manual) must be done at least
once a year by the manufacturer or company expressly authorized by the manufacturer. In the contrary case, the
