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. The "Temperature" LED 

flashes and the data in flashing is the actual temperature in the current test box.

The data of the heat rejection rate will be always held after the temperature test begins 

and can be held off by resetting. The new measurement can be undertaken only after 

releasing the data-hold.   

III: Temperature comparison test 

Two independent infrared lamps and temperature probes are available for LS301, 

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 LS301. 

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. 

The temperature difference in left and right boxes manifests different thermal 

properties between two samples.
