.2 Precautions and restrictions before use  
To ensure proper use of this product, please read the following items and restrictions carefully before  
using.  
1
2
. Please read this manual carefully before using the product.  
. 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.

. 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.  
. 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
6
. Do not place an open flame source such as a lit candle on top of the unit.  
. do not open the case to avoid electric shock. Only those who are professionally trained  
and certified by our company should open them.

. The best test distance for the infrared thermometer is 50-75cm, and the temperature  
measurement error within 1m is ±0.5.  
. 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.  
. To ensure measurement accuracy, it is recommended to use at an operating environment  
of 15°C to 30°C and RH<85% (non-condensing).  
1
1
0. Use the infrared video thermometer in a windless indoor environment.  
1. 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.  
1
1
2. 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.  
3. 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.

4. When switching to a new environment, turn the product on and leave it for 10 to 15  
minutes before measuring.  
5. The ambient temperature should be stable and should not be measured in areas with high  
airflow such as fans, air conditioning outlets, etc.  
6. 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.  
7. The thermal imager measures the surface temperature of the object, and if temperature  
compensation is required, go to the Setup page to adjust it.

8. 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.  
9. When the actual temperature differs from the measured temperature due to  
environmental factors, the infrared video pyrometer needs to be temperature  
compensated.

0. Do not start measuring other subjects immediately after measuring the temperature of an  
extremely high or low temperature object, and leave for 10 minutes.  
1. 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.  
2. The infrared image pyrometer should not be used in an electromagnetic interference  
field.  
3. The infrared thermometer has operating limitations in small spaces because it is too close  
to focus.  
BlueEyes Technology

4. If the screen is completely white, it is likely that the screen, the mask or the front lens is  
fogged with condensation.  
5. 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 temperature  
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.  
2
6. 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.

.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.  
. The machine must be placed away from heat sources such as heaters, heat regulators,  
furnaces and other heat generating products.

2. Emissivity  
Emissivity is a measure of the relative strength of the energy released by the surface of an object in the  
form of thermal radiation. The emissivity of an object is equal to the ratio of the energy emitted by the  
object at a certain temperature to the energy of blackbody radiation at the same temperature. The  
emissivity of a black body is equal to 1, and the emissivity of other objects is between 0 and 1. Emission  
rate is a pure quantity. In general, the darker the color of the material or the rougher the surface, the  
closer the emissivity will be to 1.  
The following is a reference for the emissivity of various materials
