11.2. TECHNICAL FACTOR MEASURE
The high voltage value is measured with a non-invasive instrument.
The anode current is controlled inside with measurement resistors and circuits to obtain very precise measurements.
Operation of the circuits is checked at the time of testing. Once assembled, the anode current can no longer be
directly measured.
The exposure time should be evaluated by measuring the time that elapses from the moment in which high voltage
exceeds 75% of the nominal value to the moment in which it drops below this value. Considering the high gradient of
the rising and trailing edges of the anode voltage and squaring due to inherent filtration, use of a threshold ranging
from 25% to 75% may be considered non-influential.
