While editing the shape of the triangle the sensor is simultaneously recalibrated.
If the evenly shaped triangle can not be reached, the second primary collimator position must
be adjusted in vertical direction. Refer to the section 7.8 "Second primary collimator adjust-
ment" on page E-78 for information on how to align it.
