8.6 Exposure with the supplied X-ray button
1.
Using the main keypad, select the exposure time as described in
paragraph 8.4, based on the selected mode.
2.
Move away the distance permitted by the X-ray button cable in the
opposite direction of the X-ray beam.
3.
Press the X-ray emission button and hold it down during the
exposure.
4.
A yellow light and an acoustic signal indicate the start of exposure.
WARNING:
•
The X-ray emission button is a “dead-man” control; therefore it must
be held down during the entire exposure.
• If the button is released before the end of the exposure, the emission
is automatically stopped; this situation is shown on the display by
the message “
E13
”, if the button was released during pre-heating and
“
E12
” if the button was released during the emission of X-rays.
This message will remain displayed until the “Increase” key
is pressed.
5.
At the end of exposure, the system starts the tube-head cooling cycle
(30 times the exposure time). The time until the end of the pause is
shown on the display.
NOTE:
For all exposure times shorter than 0.20s, the cooling pause is constant
and equal to 6s.
6.
If the X-ray button was already pressed at the end of the cooling
pause, the exposure will be inhibited and the error “
E11
” will be
displayed.
NOTE:
All the system statuses are shown on the display during the exposure:
preheating, X-ray emission and the cooling pause.
