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 performed. 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 sec-
onds 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:
