/nm at 12 inches (30.5 cm) based on the factory
calibration. If the reading is not within the tolerance, note the value for use later in this
procedure.

Check the intensity on the LOW setting:
•
Place the light intensity rocker switch in the LOW position.
•
Obtain a peak reading as in Step 4.
Note:
The radiometer should read 15 ±2 µW/cm

/nm at 12 inches (30.5 cm) based on the factory
calibration. If the reading is not within the tolerance, note the value for use later in this
procedure.

If all criteria in the previous steps were met, the UUT performance has been verified and the UUT can
be returned to the user. Turn off the UUT and ignore all further steps in this chapter.

Place the light intensity rocker switch in the LOW position.
•
Examine the photometer reading.
•
If necessary, use the adjustment tool to adjust potentiometer B for a light intensity of
15
±
