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.Pay attention to the measuring area.The actual detection of infrared thermometer is the artery skin temperature at forehead or behind the ears.Since the forehead area is not that small and the artery distribution of every person is different,therefore,when there is abnormal body temperature stated,it is advised to test more with different positions,each position should be measured three times at the same time,and subject to the highest data as artery skin temperature.

Considering the ear back area is relatively small and easier to find the artery location,therefore,it is recommended to test the ear back if possible,and pay attention to disclose the ear back without hair.

What thermometer detects is the temperature of baby's forehead artery,so if measuring please aim at the middle of eyebrows,eyebrow position,temple position and ear back position these four positions,each position measures three times and subject to the maximum value.

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 after having ice compressn,or sweating,or facing the air conditioning,or after shower,or no ready for heat balance and so on.

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.

Infrared thermometer is calculated by collecting the radiation of the human body infrared ray, is a passive receiving infrared radiation energy, products do not directly contact with the human body, will not bring different human body cross infection, the company's production of thermometer on the human body no radiation, so harmless to the human body.

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.
