Operating Instructions
Power ON/OFF
Press the
M-H D-H W/BR
Battery Replacement
Buttons
button to turn the meter ON or OFF.
Solar Sensor
1. The solar sensor is permanently attached to the meter.
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.
Unit of Measure Selection
Press the
M-H D-H W/BR
Battery Replacement
Buttons
button to toggle between BTU (ft2xh) and W/m² units
of measurement.
Measurement Range Selection
Press the
M-H D-H W/B
R
Battery Replacement
Buttons
button to select the preferred measuring range. The
available ranges are: 199.9 or 1999.
MIN/MAX
1. Press the
M-H D-H W/BR
Battery Replacement
Buttons
button to enter the MIN/MAX function.
2. The "MAX" indicator will appear on the display.
3. Under this function the maximum solar value is displayed and
updated when a new maximum data value has been taken.
4. Press the M-H
D-H W/BR
Battery Replacement
Buttons
button again and the "MIN" indicator will appear on
the display.
5. Under this function the minimum light value is displayed and updated
when a new minimum data value has been taken.
6. To exit the MIN/MAX function and resume normal operation, press
and hold the MIN/MAX button for approx. 2 seconds.

Data Hold
1. While taking a measurement, press the
M-H
D-H
W/BR
Battery Replacement
Buttons
button to freeze the
current readings on the display.
2. While in this mode a "D-H" symbol will appear.
3. Press the
M-H
D-H
W/BR
Battery Replacement
Buttons
button again to resume normal operation.
Zero Adjustment
1. Before taking a light measurement, cover the solar sensor with the
provided protective cap.
2. If the LCD display does not show a value of zero, locate the zero
adjustment potentiometer screw on the side of the meter as
indicated by "0’ ADJ".
3. With a mini athead screwdriver, ne-tune the zero adjustment
potentiometer screw until the LCD displays "00.0".
4. Remove the protective cap and begin measuring.

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.
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 efciency of the window’s
solar lm.
