Solution:
1.Check the operation mode.Human body temperature measurement must be proceeded with body temperature mode.
2.Check all Settings are factory original settings or not,especially F1 must be 0.
3.It is crucial to pay attention to the measuring area when using an infrared thermometer. The actual detection targets the artery skin temperature either at the forehead or behind the ears. Given that the forehead area is relatively larger and the distribution of arteries varies among individuals, it is advised to perform multiple tests using different positions.
Considering that the ear back area is relatively small and the artery location is easier to find, it is recommended to conduct tests on the ear back whenever possible. It is essential to ensure that the ear back is free from hair, as this can affect the accuracy of the measurements.
What the thermometer detects is the temperature of the baby's forehead artery. When measuring, please aim at four positions: the middle of the eyebrows, the eyebrow position, the temple position, and the ear back position. Take three measurements at each position and record the maximum value obtained.
4.Pay attention to heat balance of the thermometer itself and the tested person.The heat balance of machine means that when the ambient temperature around thermometer changes greatly,please wait for 15-20 minutes firstly before testing.And for heat balance of tested person,the person need to wait 15-20 minutes to clam down before test.
5.Please be aware not to measure the temperature after applying an ice compress, sweating heavily, being exposed to air conditioning, taking a shower, or if the heat balance is not yet achieved.
6.Measuring distance should not be too far away,1-2 cm away from the forehead is recommended.
Answer: if it is used for the first time, please follow the following steps:
Step 1: place the thermometer in a stable ambient temperature for more than 30 minutes;
Step 2: use a traditional mercury thermometer or electronic thermometer to measure someone, assuming a temperature of 36.8 degrees Celsius;
Step 3: use a non-contact infrared thermometer to measure the same person. Pay attention to the measurement distance and measurement method: keep the distance between the thermometer and the forehead between 1-3cm, and remove any obstacles that may affect the measurement, such as hair and sweat. If the same temperature is 36.8 ℃, the thermometer is set normally and can be used normally, If you get a lower reading of 36.4 degrees Celsius with a difference of 0.4 degrees Celsius, you can set F1 to "0.4 degrees Celsius". On the contrary, if there is more than 0.4 degrees Celsius, you can set F1 to "- 0.4 degrees Celsius"
This kind of problem is generally caused by the wrong setting of the thermometer, you can refer to the correction Settings in the instructions.
The infrared thermometer operates by collecting the infrared radiation emitted by the human body. It is a passive receiver of infrared energy and does not require direct contact with the human body during use. As a result, there is no risk of cross-infection between individuals when using the product.
It is important to note that our company's produced thermometers do not emit radiation onto the human body, making them entirely safe and harmless for use.
If it is the first time to use the thermometer, follow the following steps: Step 1: Place the thermometer at a stable ambient temperature for more than 30 minutes; Step 2: Measure someone with a conventional mercury or electronic thermometer, assuming a temperature of 36.8 degrees Celsius; Step 3: Use a non-contact infrared thermometer to measure the same person, pay attention to the measurement distance and measurement method: Keep the thermometer 1-3 cm away from your forehead, and remove any obstacles that might interfere with the measurement, such as hair and sweat. If you get the same temperature of 36.8 degrees Celsius, the thermometer is set and can be used normally. If you get a lower reading of 36.4 degrees Celsius, a difference of 0.4 degrees Celsius, You can set F1 to "0.4 ° C", or vice versa, for 0.4 ° C more, you can set F1 to "-0.4 ° C".
Possible reasons are as follows: 1) The measurement distance is too far, which may measure the temperature of the surrounding environment. The designed measurement distance of this thermometer is 1-3 cm, and the best measurement distance is about 1 cm; 2) There is a deviation in the measurement position. When taking the temperature, aim the thermometer at the center of the forehead (above the brow) and keep it vertical; 3) Lo may appear when the subject's forehead is covered with hair, sweat or water, has been pasted with fever reducing tape or taken fever reducing medicine, has been blown on the forehead against the air conditioner, or has strong wind blowing on the forehead surface. Please let the subject stand still in a relatively static environment for 5-10 minutes before measurement; 4) there are very few people on the forehead surface temperature is lower than the average person, at this time of the test results were probably "Lo", can put the thermometer to measure "surface temperature" model, and then measure the forehead surface temperature of others, do a contrast, could be determined when the person was normal at this time, mainly focused on the high temperature alarm or fever "Hi"; 5) The parameter of F4- overall temperature offset is wrong.
This kind of problem is generally caused by the wrong setting of the thermometer, you can refer to the correction Settings in the instructions.
