Required measurement devices: lux meter
NOTE
If the MOBILETT is equipped with a DAP measuring system, re-
move the DAP ionization chamber first.
PMF Luminance
If the collimator lamp is switched on for the purpose of illuminating the radiation field, the
average luminance must be 180 lux at a distance of 100 cm. The average luminance is
determined by taking measurements in the approximate center of each of the four quad-
rants of the light field,(Fig. 32 / p. 54) .
