1.2 Precautions and restrictions before use
To ensure proper use of this product, please read the following items and restrictions carefully before
using.
1. Please read this manual carefully before using the product.
2. Infrared imaging thermometers can set the temperature compensation according to the
field environment. If infrared imaging thermometers are used to measure the surface
temperature of the human body, the surface temperature will change due to the
measurement environment, the shape of the human body surface and the wearable, etc.
The actual temperature of the human body must still be measured by government
certified medical devices, such as ear guns, etc. Thermal imaging devices are not medical
grade devices and cannot be used as the main actual temperature measurement of the
human body. Temperature results are for reference only and should not be used as a
basis for medical identification.
3. To avoid the risk of fire, electric shock or product damage, do not expose the machine to
rain, dampness or liquid splashes, and do not place water containers such as vases on the
machine.
4. Do not place this machine in a bookcase, hidden cabinet or other enclosed space. Do not
allow curtains or any other object to block the ventilation holes to avoid the risk of
electric shock or fire from overheating the machine.
5. Do not place an open flame source such as a lit candle on top of the unit.
6. Do not open the case to avoid electric shock. Only those who are professionally trained
and certified by our company should open them.
7. The best test distance for the infrared thermometer is 50-75cm, and the temperature
measurement error within 1m is ±0.5℃.
8. The infrared video pyrometer is mounted on a three-legged camera stand, which is used
for horizontal detection to achieve a more accurate measurement rate.
9. To ensure measurement accuracy, it is recommended to use at an operating environment
of 15°C to 30°C and RH<85% (non-condensing).
10. Use the infrared video thermometer in a windless indoor environment.
11. Pedestrian flow control should be carried out at the detection site, and the measuring
line should be mainly passed by a single person in slow steps, otherwise it will affect the

BlueEyes Technology
www.BlueEyes.com.tw
accuracy of the infrared video pyrometer measurement.
12. The subject should be kept at a certain distance from the former, or the direction of the
thermal imager should be changed to avoid overlapping images from affecting the
temperature measurement. Thermal radiation can also be affected by the passing of time
by keeping your head down or wearing a hat, which should be avoided as much as
possible, otherwise the accuracy of the infrared thermometer measurements will be
affected.
13. The ambient temperature of the test should be stable and should not be measured in
areas with high airflow such as fans, air vents of air conditioners, etc. Avoid heat sources
(e.g. drinking fountains, overhead lamps, sunlight, etc.), air outlets (e.g. ventilation doors,
fans, etc.) and infrared surveillance cameras when erecting or installing infrared video
thermometers.
14. When switching to a new environment, turn the product on and leave it for 10 to 15
minutes before measuring.
15. The ambient temperature should be stable and should not be measured in areas with high
airflow such as fans, air conditioning outlets, etc.
16. When the measurement object comes from a place where the temperature difference in
the measurement environment is relatively large, it is necessary to stay in the
measurement environment for 10 to 30 minutes before taking the measurement.
17. The thermal imager measures the surface temperature of the object, and if temperature
compensation is required, go to the Setup page to adjust it.
18. This product has a self-calibration function, if the reading has a rapid jump, please wait
for 30 seconds or so, wait for the reading to be stable before taking the measurement.
19. When the actual temperature differs from the measured temperature due to
environmental factors, the infrared video pyrometer needs to be temperature
compensated.
20. Do not start measuring other subjects immediately after measuring the temperature of an
extremely high or low temperature object, and leave for 10 minutes.
21. Infrared video thermometers should not be used in places with strong sunlight because
the radiant heat of the sunlight will affect the temperature sensor's detection.
22. The infrared image pyrometer should not be used in an electromagnetic interference
field.
23. The infrared thermometer has operating limitations in small spaces because it is too close
to focus.

BlueEyes Technology
www.BlueEyes.com.tw
24. If the screen is completely white, it is likely that the screen, the mask or the front lens is
fogged with condensation.
25. An infrared thermometer measures and captures images by the infrared radiation heat
emitted by an object. In fact, since the radiation is a function of the surface temper ature
of an object, an infrared video thermometer can calculate and display this temperature.
However, the radiant heat measured by an infrared imaging thermometer is not only
dependent on the temperature of the object itself, but is also a function of emissivity.
Radiation can also come from the surrounding environment and be reflected on objects.
Radiation from an object and reflected radiant heat are affected by atmospheric
absorption. To obtain accurate temperature measurements, it is necessary to compensate
for some effects caused by different sources of radiation. Therefore, the thermal imaging
camera must make reference to the emissivity and reflection of the object's apparent
temperature parameters.
26. The application of infrared thermal imaging cameras has its limits. In fact, it is judged by
experienced users that the absorption and radiation of infrared rays on the surface of
different materials to form a thermal image will be affected by the material and geometry
of the surface. That is, we cannot rely solely on the images we obtain to determine
whether they are actual differences or changes in temperature.
1.3 place
1. Place the machine on a flat surface, away from direct sunlight, and avoid high
temperature, high humidity and frequent vibration. Failure to do so will result in damage
to the chassis and other internal parts, thereby shortening the life of the machine.
2. The machine must be placed away from heat sources such as heaters, heat regulators,
furnaces and other heat generating products.
3. Use the product in a dry, ventilated and stable environment to avoid malfunction.
1.4 cleanliness
1. Unplug the power cord before cleaning the unit.
2. For difficult to clean spots, soak a soft cloth in water, wring it out, wipe it off, and dry the
machine with a soft dry cloth.

BlueEyes Technology

3. Do not use any solvents, such as thinners and gasoline-based solvents, as such solvents
can damage the surface of the machine.
1.5 Pedestrian flow control and route planning
It is recommended that the detection of the field of pedestrian flow control, the use of railings or red
dragon posts to guide the queue of people, the measurement of the moving line to a single person to
pass slowly as the main, requiring the subject to take off the hat, do not bow their heads, and the
former to maintain a certain distance, can be social distance of 1.5m for the front and back of the
distance between the two people, otherwise it will affect the accuracy of the measurement of infrared
video thermometer.
The following is our proposed route arrangement.

BlueEyes Technology
www.BlueEyes.com.tw
1.6 Height and shooting angle
Infrared video thermometer with a standard 1/4 inch camera lock hole, mounted on a standard tripod
used by the camera, set the height of the general person above the height, about 180-190 cm or so, if it
is an elementary school, tutorial class, safety class and other institutions, depending on the average
height of the students can be adjusted, about 10-15 cm or so above the average height, infrared video
thermometer shooting angle to look down 10-15 degrees frontal view, single person one-way through
the basic policy, when the distance from the infrared video thermometer about 50 cm after turning to
pass, to ensure that the subject can be infrared video thermometer to capture the forehead
temperature.
The following is our recommended height and shooting angle for the thermal imager.

BlueEyes Technology
www.BlueEyes.com.tw
1.7 Temperature detection of major areas
The temporal artery from the forehead to the upper edge of the temporal cavity is the main
temperature detection area, which may affect the accuracy of the temperature measurement if the
subject wears a hat, has a low head, has a long fringe, and has too large a frame.
