Make measurements with the sensor face at a 90-degree angle to the ceiling and floor and positioned in
the center of the fixture (maximum UVC output). To test for proper UVC output, at a distance of 1 M from
the center of the fixture raise the sensor into the UVC beam and find the maximum reading. For the
Sanilume SL-36KT-75, the reading should be about 240
𝜇𝜇𝜇𝜇
/
𝑐𝑐𝑚𝑚
2
and 140
𝜇𝜇𝜇𝜇
/
𝑐𝑐𝑚𝑚

for the SL-36KT-40.
To test for safety:
•
Measure every 3 ft. back from the fixture, up to 15 ft.
•
Measure near walls
•
Measure near any obstructions/protrusions that intersect with the UVC beam
IF ANY READING IN THE ROOM IS ABOVE 0.2 µW/CM
2
ANYWHERE ABOVE 7 FT. IN HEIGHT FROM
THE FINISHED FLOOR, ADJUSTMENTS MUST BE MADE.
1. Check the side-to-side level. If the apertures are not set the same or the power cable is
pulling on the fixture, the level will be off.
1.
If the reading that is too high is at the location where the UVC is being reflected down from
the inside the fixture (about 3-7 ft from the fixture) First, try and raise the fixture by 1 or 2
inches. Recheck the level and retest.
2.
If the high readings are caused by ceiling reflections, then lower the aperture setting as
previously described.
