Introduction
Thank you for selecting the Extech Model SP505 Solar Power Meter. This device measures the
power of solar radiation. Use the SP505 to measure the effectiveness of solar film, measure solar
radiation, check solar insulated windows, check headlight intensity, and find the optimal
incidence angle for solar panels and solar water heaters. This device is shipped fully tested and
calibrated and, with proper use, will provide years of reliable service. Please visit our website
(www.extech.com) to check for the latest version and translations of this User Manual, and for
Customer Support.

Operation
Power the Meter
Press the button to turn the meter ON/OFF. If the meter display does not switch ON, please
check the batteries (2 x 1.5V ‘AAA’) in the rear compartment. The meter has an APO feature
where the meter automatically switches off after 10 minutes of inactivity.
Zero the Sensor
Cover the sensor, and press the button to zero the display before use.
Range Selection
Short press the button to toggle the range of the meter. The meter display range toggles
between 0.1 and 1 unit resolution.
Unit Selection
Short press the button to toggle the units between W/cm2 and BTU (ft2*h); the lower
display area will show the selected units.
Data Hold
Short press the button to freeze or unfreeze a reading on the display.
Testing Solar Power
With the meter ON, zero the display and then point the sensor (top of meter) toward the sun
and read the displayed power measurement. A display of ‘OL’ indicates that the measured
power is beyond the range of the meter.
Other Application Examples
Automobile Headlight Measurements
1. Turn on the headlights and short press the power button to power the meter.
2. Face the sensor (top of meter) toward one headlight and then the other, recording each
reading.
3. Turn the high beams on and measure both headlights again, recording the readings.
4. Retain the recorded readings with the vehicle for reference.
5. Short press the power button to power OFF the meter.
Measuring the Solar Insulation of Windows
Use the meter to test the solar film of car windows or the heat efficiency of windows in
residential or commercial properties.
1. Turn on the meter and zero the display before taking a measurement.
2. With the window closed, aim the sensor toward the sun and record the reading.
3. Open the window and aim the device toward the sun, recording the reading.
4. Compare the two values to determine the heat efficiency of the window. Test the windows
at least once a year to monitor efficiency.
