LS300 solar film temperature tester
Instruction manual V3.1
The LS300 solar film temperature tester is designed to demonstrate heat-insulating
property of the solar film. It can be used to measure the temperature value.
Two 150w Philips infrared lamps.
"Temperature" LED to display the current temperature value.
"Difference temperature" LED to display the difference temperature from testing
begin to end.
I: LS300 parameters
1. Temperature measurement accuracy for a single side: ±0.5℃
2. Heterogeneous temperature degree of two infrared lamps: 2℃
3. Temperature measuring range: -55℃---- +125℃
4. Time for temperature test: 1 min
5. Size of the testing glass: 200mm×160mm
6. Gross weight: about 12 kg.
7. Dimensions: 340mm×200mm×400mm(L*W*H)
8. Power supply: 220V AC
II: Operations
There are three testing statuses of the instrument: waiting for testing, being testing and
end of testing
Waiting for testing: the "difference temperature" data is zero and flashes to indicate
waiting for testing. Under this status, press the button to enter into the status of being
testing.

Being testing: the "difference temperature" data stops flashing, and the infrared lamps
are lit up. After the 1-min test ends, the infrared lamps lights off and the instrument
automatically enters into the status of end of testing.
End of testing: temperature value are held. Press "Reset/test" to release the
data-hold and enter into the status of waiting for testing.
1. Powering on
Power the instrument on by plugging into 220V AC power source.
2. "Reset/test" button
When the "difference temperature" LED flashes, the data on "temperature" LED
refers to the actual temperature in the current test box. When the gap in actual
temperature between left and right test boxes falls within 1 degree, the test data becomes
more accurate.
When the " difference temperature " LED flashes and the gap in actual temperature
between left and right test boxes falls within 1 degree, press the button "Reset/test" to
begin the test, with both infrared lamps lit up and the temperature in left and right test
boxes climbing up.
The test will end after one minute. At that time, the infrared lamps go out, and the
temperature values obtained from the test are displayed respectively on the temperature
LEDs in left and right test boxes and remain unchanged.
Press the button "Reset/test" again to release the data-hold.
III: Temperature comparison test
Two independent infrared lamps and temperature probes are available for LS300,
which enable the temperature comparison test to measure heat-insulating property of two
different film mounting glasses. See the followings for test procedures:
1.Place two samples respectively into text boxes in left and right sides of LS300.
2.Press "Reset/test" to light up two infrared lamps and start the test. The temperature in
left and right boxes begins to climb up.
3.The test ends after one minute. Then, the infrared lamps go out, and the temperature
values obtained from the test are displayed respectively on the temperature LEDs in
left and right test boxes. Such values remain unchanged and cannot be reset until
the button "Rest/test" is pressed.
4."Difference temperature" LED to display the difference temperature from testing
begin to end of each boxes side.
IV: Precautions
1. After the test ends, the fan will automatically start for cooling and stop after four
mins.
2. As the test data remains unchanged after the test ends, it's necessary to press
again the button "Reset/Test" to reset the temperature difference and temperature
data. After resetting, the temperature data will flash and the displayed data is the
actual temperature in the text box.
