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:
If an error is detected, the test program will be aborted. A beep will be audible and a mes-
sage will be displayed:
If the test ends successfully, the display will show:
Duration: Max. 20 seconds.
P02 - Rotation test
5
(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:
After acceleration, the display shows the actual rotation frequency:
