a) Operating on the main keyboard, select exposure time as described
in paragraph 7.2, according to the selected way.
b) Enable exposure by pressing key ( 3 ) "Ready".
NOTE:
When the READY key is touched, the equipment will not only enable
exposure but it will also start showing the exposure time on the display
calculated according to line voltage fluctuation compensation (see
paragraph 5.1).
c) Walk away as far as the X-ray button cable will allow, in the opposite
direction to the X-ray beam.
d)
Press the X-ray emission button and keep it pressed during
exposure.
e) Exposure starts when the yellow light and an acoustic signal come
on.
WARNING:
•
The X-ray emission button is a "dead man" control; so it must be
held pressed during the whole exposure.
If the button is released before the exposure ends, the emission is
automatically stopped; this situation is shown on the display by the
flashing message “
E P ”, and the luminous signals on the keyboard
will be off. This signal stays until one of the time increase keys is
touched.
•
If there is an excessive variation in line voltage which would require
an actual exposure time of 4 or more seconds, the equipment will not
execute the exposure. In this case, the display shows the correct
exposure time according to the line fluctuation.
•
If the voltage is outside an acceptable range, the display will show
respectively ‘LLL’ (voltage too low) and ‘HHH’ (voltage too high).
•
The touch of the X-ray button with non enabled exposure will display
the value of the actual exposure time of the latest exposure made, or
the time selected in the case of a first exposure.
f) When the exposure finishes, the equipment starts the tubehead
cooling cycle (32 times the exposure time); this situation is shown by
the flashing of the machine enabling light, while the time that must
elapse before the pause end is shown on the display.
