3.3
Interrupting an Exposure During the Beam Ramp Up
If the X-Ray beam is interrupted in any way (for example Door opened, E-
stop,
Ray off) during the kV ramp (that is, without the mA to load the kV), it
will take 5-8 seconds for the kV to drop below the 5kV level. In this
situation the HT ON indication continues (even though the beam is
interrupted) until the kV drops below 5kV. This is the correct operation of
the system in this circumstance.
If possible, the beam should only be interrupted when the kV has ramped all
the way up and the mA has started or stabilised. This can be seen in the
‘actual’ kV and mA values on the exposure
screen.
