Blackbody: power on and preheat for 20 minutes; thermal imaging equipment: power
on and preheat for 60 minutes, with the best effect.
3. Whether it can be installed in outdoor or semi outdoor environment.
Because the outdoor temperature, wind, humidity and other environmental factors
have a great impact on the temperature measurement of the thermal imaging surface,
it is not recommended to be installed outdoors or in the area directly connected to the
outdoor, but in a closed and relatively stable environment without wind.
4. Why is it recommended to measure the temperature of frontal forehead?
First of all, different people's forehead temperature also has temperature difference. In
the case of mask, the exposed area of forehead is relatively large, which is more
convenient for temperature measurement.
The actual temperature of the front face and the side face of the same person / same
position is different. With masks, the high temperature points are mainly in the
forehead, ears and neck, and the temperature is different among different people.
Therefore, it is required to face the camera and test the frontal temperature uniformly
to reduce the impact of temperature difference between different parts.
5. What is the best temperature range for temperature measurement?
The best temperature range of indoor wind free and stable environment is 10
℃
~
30
℃
6. The best distance for temperature measurement?
The best temperature measurement distance is the same as the distance between
blackbody and equipment. 3.5mm detection distance is 2m, and the transverse width
of 2m is about 1.5m; 7mm detection distance is 3m, and the transverse width of 3m is
about 1.3m; the temperature measurement value far from the optimal distance will be
reduced, and the temperature measurement value close to the optimal distance will be
increased.
7. How many heads can be tested?
As shown in the figure below, in normal use, there are not many people (width 1.3-
1.5m) at the best distance of temperature measurement. There is no limit to the number
of heads in the detection area, but it is too far or there is overlap, which may result in
missing or inaccurate temperature measurement. It is recommended to test one by one.
8. Why does the image of thermal imaging channel get stuck after a period of time?
Is it normal?
Normal. In order to ensure image uniformity and temperature measurement accuracy,
thermal imaging needs a period of time to set the blank back to zero for correction.
During the process of setting the blank, the image will get stuck once, and the internal
part of the equipment will "click" once, which is a normal situation.
9. Why thermal imaging does not measure temperature after the first
configuration
