rupted more than 3 times, the expo-
sure will be interrupted.
•
Faulty inverter/inverter control
•
Check the inverter current (see
sections "Error diagnosis HT and
single tank", "P12 - Inverter and
single tank test" and "P13 - Inverter
test").
•
The X-ray tube may have arced
during the exposure. Tube arcs can
occur if the first exposure after a
long interval is an exposure with
high kV values.
The unit has to be started with
several exposures at high mAs
values. The kV values selected
should be increased from 40 kV to
133 kV.
