4. OPERATION

4.1 Operating Conditions and Set-up
AutoLight 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 surfaces while readings are being taken off the main unit. For best
results you should take several readings to ensure consistence across the window.
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 three easy steps:
Step 1 - Align: Align AutoLight to the side window or windscreen so that the
light source and sensor are on opposing sides.
Step 2 - Activate: After aligning AutoLight, press the measurement button to take a reading
of the light transmitted through the window.
Step 3 - Annunciate: After the test is completed, the display shows the percentage of light
transmitted through the window. AutoLight 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 10 seconds, before AutoLight turns off automatically.
Repeat steps for each window area to be tested.
Step 1 – Align
