List of test programs available in service mode

P01 - Filament test

(Wiring diagram, page 160)
At the beginning of the program, the tube is heated for 5 seconds in standby mode, fol-
lowed by 12 seconds at high heating. During the test "FIL_VAL" is checked and must be
stable and within the limits. During the test the display shows:
kV mAs
FIL tESt = Filament test
If an error is detected, the test program will be aborted. A beep will be audible and a mes-
sage will be displayed:
kV
P01 Err 22 = Filament preparation error
P01 Err 13 = Filament supply error
If the test ends successfully, the display will show:
kV
P01 PASS = Filament test in program P01
Duration: Max. 20 seconds.

P02 - Rotation test

(Wiring diagram, page 150)
Accelerate the anode with a 160 Hz frequency during two seconds. After this first acceler-
ation, the speed is measured and if necessary, a second acceleration of two seconds
occurs. When the correct speed is reached, the anode will rotate freely for 20 seconds or
until the rotation frequency is below 142 Hz before it is braked during 9 seconds to a stop.
An error message will be displayed after two unsuccessful attempts to accelerate the
anode or if the anode looses speed too fast. When the test is activated, the display shows:
kV
Rot tESt = Rotation test
After acceleration, the display shows the actual rotation frequency:
kV
