3 - 6 Function checks
Evaluation:
• Measure the deviations (X1,X2,Y1,Y2) between the edges of the light field and of the
radiation field on all four sides, as in the sketch.
• Calculate the sum of the deviations in the X and Y directions (without regard to sign).
• The longitudinal deviation ( SY) as well as the width deviation ( SX) has to be smaller
than 1.6 cm.
• Switch OFF the POLYMOBIL Plus and disconnect the line voltage cable.
In case of deviations greater than 1.6 cm, see Service Instructions
Chapter "Checking coincidence of light and radiation fields".
