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.
IV. Temperature comparison test
Two independent infrared lamps and temperature probes are available for the instrument, which enable
the temperature comparison test to measure heat-insulating property of two different film mounting
glasses. See the followin for test procedures:
1. Place two samples respectively into text boxes in left and right sides of the instrument.
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.
