List of test programs available in service mode

P01 - Filament test

(Wiring diagram X037E, page 160)
At the beginning of the program, the tube is heated for 5 seconds in stand-by 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. An audible beep will sound and a
message 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, if the FW version is higher than 1.4 or 1.4E

(Wiring diagram X037E, page 150)
Accelerates the anode with a 160 Hz control signal during two seconds. After this first
acceleration, the speed is measured and if necessary, a second acceleration of two sec-
onds is made. When the correct speed is reached, the anode will rotate freely for 20 sec-
onds 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 acceler-
ate 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
