When taking measurements:
Be particularly careful when measuring voltages exceeding 20V to avoid risks of electrical shocks. Avoid doing that in humid or wet places.
Avoid doing that in rooms where explosive gas, combustible gas, steam or excessive dust is present.

• Keep you insulated from the object under test.
  Do not touch exposed metal parts such as test lead ends, sockets, fixing objects, circuits etc.

• Avoid doing that if you notice anomalous conditions such as breakages, deformations, fractures, leakages of battery liquid, blind display etc.

Power button POWER

• Press the “POWER ” button to turn ON the power. The display comes alive.
• Press the “POWER ” button once again to turn OFF the power and put the device go into sleep mode. The display changes from light to dark.

Lock up Peak button

• When you test in W/m2 or BTU (ft2 *h) Press the “PEAK” key can trace the pulsing signal >100mS and hold its peak value. Press this button once again to deactivate it.
• When the “PEAK ” button is functional, the “ RANGE ” button is disabled.

*BTU (ft2h)**

• Press the “Btu ” button to go into Btu (ft2h) mode, The screen displays Btu (ft2h). if screen displays W/m2, To select a different unit, Press the “Btu ” button to switch from W/m2 to Btu (ft2*h) .

W/m2 button

• Press the “W/m2 ” button to go into W/m2 mode. if screen displays Btu (ft2h) , To select a different unit. Press the “W/m2 ” button to switch from Btu (ft2h) to W/m2.

Data hold button

• Press the “ HOLD ” button to go into hold mode, and “HOLD” appears on the screen to allow you to read the data. Press this button once again to deactivate it.

Auto Range button Large integrated circuit design

• Press the “POWER ” power button to turn ON the power and put the device to operating mode. If “199.9” comes up on the screen, it suggests
• the device will become overloaded or has become overloaded “1”. In this case, press the “RANGE ” button, and“1999” or your acquired value then comes up.

TEST PROCEDURE

• Measure your car’s headlights:

• Turn ON your car’s headlights. Then turn ON the solar meter, and “00.0” appears on the screen. Put the device down close to the headlights. Switch between high beam and low beam, and light intensity values appear on the screen. Both the right and left headlights must be tested. Note the values and put them in your car for reference.(Picture 2)

• Measure the effect of solar insulation of your vehicle’s windows:

• Press the “POWER” button to turn ON the solar meter, “00.0” appears on the screen. Aim the device at the sun and close to a window, and the intensity appears on the screen. Open the window and aim the device at the sun. Compare the value against that acquired when the window is closed to understand the efficiency of the window’s solar film. Test your new car and preserve the measurements in it. After that, test it at least once every year. (Picture 2)

  Measure the solar insulation effect of your house’s windows:

• Close the window. Press the “POWER ” button on your solar meter, and “00.0” comes up on the screen. Put the device close to the window and aim it at the sun. Compare the value against that acquired when the window is closed and the device is placed at the same position, In order to understand the window’s heat efficiency. (Picture 3)
