Checking the light intensity

Equipment required: Lux meter
NOTE
When a collimator lamp is used to define the X-ray field, it shall provide an average illumi-
nation of no less than 180 lux at 100 centimeters. The average illumination shall be based
upon measurements made in the approximate center of each quadrant of the light field
(Fig. 4).
If the illumination is less than 180 lux, check the lamp supply. Refer to wiring diagram
X037E, page 180.
