(Passing means a sigma of equal to or less than
(±0.5) .)
NOTE
This is not an absolute specification.
5. Bring up X-ray High Voltage
— This step ramps
the high voltage up slowly without drive current
(no X-ray generation at this time).
a. Use a volt meter to recheck the Vacion Power
Supply at test point
J04000 . ( Figure 11 on page
26 ) The reading must be less than
10 mV
before
operating the X-ray system.
IMPORTANT
If the reading is NOT equal to or less than 10 mV, then
allow more time for the Vacion Pump to operate (and
recheck) before ramping up the high voltage.
b. Select
System Access
then
Quit from 5DX
.
c. From the DOS prompt, type
ca
and press
Enter.
d. Type
vs xray.cfg
and edit the line Cold
Start Rampup to have a value of 60 instead of
15
CAUTION The X-ray tube has components that need to warm up
before generating X-rays. In this case, the tube has been
off for an extended period of time so it will require a 60
minute start up. Bypassing this step could result in
permanent damage to the X-ray tube.
