4. OPERATION

4.1 Operating Conditions and Set-up
AutoLight Plus has a photocell built into the light sensor tube and a constant light source
built into the light source tube. These components are fragile. Care should be taken when
handling the unit and should not be dropped or violently shaken. Avoid taking
measurements in strong sunlight as stray light may affect the reading accuracy. Aim
the light source directly at the sensor for an accurate reading. It can be fixed or held onto
one of the window surfaced while readings are being taken off the main unit.
4.2 Instructions for Use
By aligning the light source and sensor on opposing sides of the window to be tested, the
percentage of light transmitted through the window is measured.
Follow these four easy steps:
Step 1 - Align: Align AutoLight Plus MAGNETIC to the side window or windscreen so that
the light source and sensor are on opposing sides.
*FOR ALL DOOR WINDOWS: The cable MUST be over the door, as pictured, for the magnets to hold.

Step 2 - Activate: After aligning AutoLight Plus, press ON button until you see " " on the
LED window. Then press the ON button once again to take a reading of the light
transmitted through the glass window.
Step 3 - Read: After the test is completed, the display shows the percentage of light
transmitted through the window. AutoLight Plus MAGNETIC reads light transmission as a
percentage. Simply compare the reading with the specific value according to your local
regulations. The reading will remain displayed for 3 seconds, before AutoLight Plus
MAGNETIC turns off automatically.
Step 4 – View stored readings: To view stored light readings, press the ON button and do a
quick test. When the test measurement is finished, wait for about two seconds and then
quickly press the ON button to enter into viewing mode. Once in the viewing mode,
subsequent presses of the ON button will increment test number and relevant light reading
for each test will be displayed adjacently.
Repeat steps for each window area to be tested.
