2. Remove the protective cap to expose the solar sensor. When the
sensor's protective cap is removed, the solar sensor will begin to
capture light. For maximum accuracy, allow the light under test to fall
directly on the sensor as perpendicular as possible to avoid any
false readings.

Typical Applications
Measuring Car Headlights or Car Window
Solar Insulation (Fig. 1)
1. Turn ON car headlights.
2. Power the meter ON.
3. Place the sensor up close to the headlight and allow the headlight
under test to fall directly on the sensor as perpendicular and as close
as possible to avoid any false readings.
4. Switch between high and low beams.
5. Note the results.
Note: Both the right and left headlights must be tested.
Figure 1
6. For car window solar insulation, place the sensor up close to the
window and allow the sun rays to fall directly on the sensor while the
windows are closed and as perpendicular as possible to avoid any
false readings.
7. Open the window and aim the solar sensor at the sun.
8. Compare both values to verify the efciency of the window’s
solar lm.

Measuring Residential/Commercial Window Solar Insulation
(Fig. 2)
1. Make sure the window being tested is closed.
2. Place the sensor up close to the window and allow the sun rays
to fall directly on the sensor while the windows are closed and as
perpendicular as possible to avoid any false readings.
3. Open the window and aim the solar sensor at the sun.
4. Compare both values to verify the windows heat efciency.
