Common sense about body temperature
The comparison of different measurement methods.
The measured values are different if we use different measurement methods. The WHO provides normal human
body temperature reference values, please see the below table about the specific temperature difference.
| Measurement | Normal body temperature |
| methods Anal temperature | 36.6℃ 38 ~ ℃ |
| Oral temperature | 35.5 37.5 ℃~ ℃ |
| Axillary temperature | 34.7 ℃~ 37℃ |
| Cochlear temperature | 35.8 38 ℃~ ℃ |
| Oral temperature | 35.5 ℃~ ℃ 37.5 (PG-IRT1603 measured value) |
The changes in human body temperature
Human belongs to constant temperature animals, the body temperature is basically constant, but it is not totally changeless, the human body temperature is constantly
changing in a day, the details are as follows:
At night
Lowest Body temperature is lowest because of sleep and decreasing activity.(below 37℃ )
In the morning
Higher From warm bed to the lower temperature room in the morning, the whole body’s muscles get contractions and produce heat.
At noon
Highest After lunch, the human body reaches the highest temperature and the body will adjust naturally.
Three or four o’clock in the afternoon
Lower Due to physical exertion, blood sugar decreased.
In the evening
Lowest Due to the sundown, room temperature goes down.

Introduction of Measurement methods
1.Ear temperature measurement
Warm prompts:
Remove the head cover of the forehead thermometer which can measure ear temperature.
1.1 After removing the headcover, please press“ ”button on this product to enter the ear temperature to turn measurement mode, LCD will display the measurement value last time. Then put the thermometer in your ear, the ear temperature can be measured directly by pressing“ 
”button.
1.2 After 1 second, you can see the measurement result.
Note: If you did not hear the beep sound, which represents the temperature measurement has not yet been completed. Please do not remove the thermometer probe from the ear canal at this time. (If you have closed the sound indication, it will have no sound indication.)
2.Forehead temperature measurement
Warm prompts:
Install headcover of forehead thermometer which can measure forehead temperature.
2.1 After installing the headcover of the forehead thermometer, press“ ”button to turn on this product to enter the forehead temperature measurement mode, LCD will display the measurement value last time. Then the forehead thermometer is aimed at the forehead and the measurement distance should be 0~5mm, the forehead temperature can be measured directly by pressing “
” button.
2.2 After 1 second, you can see the measurement result.
Note: If you did not hear the beep sound, which represents the temperature measurement has not yet been completed. Please do not remove the thermometer probe from the forehead at this time. (If you have closed the sound indication, it will have no sound indication.)
3. Object pattern measurement
Warm prompt:
The installation of the head cover of forehead temperature has no influence to object pattern measurement.
3.1 Long press“ ”button to enter the object measurement mode for 6 seconds, and then aim the thermometer at object, the temperature of the target object can be measured directly by pressing 
button.
3.2 After 1 second, you can see the result of the measurement.
Note: If you did not hear the beep sound, which represents the temperature measurement has not yet been completed. Please do not remove the thermometer probe from the target object at this time.(If you have closed the sound indication, it will not have a sound indication.)
Product cleaning methods instructions
In order to ensure precise measurements, it is recommended to clean the device after each use.
Please use a cotton swab to dip 75% alcohol to wipe the thermometer probe and remove the residue and dirt. We recommend you clean the probe at least for 5 seconds. Then wipe the other components with a soft and dry cloth for 10 seconds at least. After cleaning, please ensure that there is no visible dirt or residue on your thermometer, Wait 10 minutes before measuring The device can be cleaned for a maximum of 40000 times.
Warm prompt:
Why do you need to do a cleaning job after each measurement?
Because infrared temperature adopts a highly sensitive technique to detect the temperature of the target object, not only will any earwax and dust paste affect the measurement accuracy, more likely to cause bacterial infection. So we suggest that you should do the cleaning job well as the picture shows after you use it every time.

NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.
| a The ISM (industrial, scientific and medical) bands between 0,15 MHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz. The amateur radio bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz to 7,3 MHz, 10,1 MHz to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHZ, 21,0 MHz to 21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and 50,0 MHz to 54,0 MHz. |
| b The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2,7 GHz are intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas.

| c Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM, and FM radio broadcast, and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Model PG-IRT1603 Infrared Thermometer is used exceeds the applicable RF compliance level above, the Model PG-IRT1603 Infrared Thermometer should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Model PG-IRT1603 Infrared Thermometer. |
| d Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m. |
Recommended separation distances between portable and mobile RF communications equipment and the Model PG-IRT1603 Infrared Thermometer
The Model PG-IRT1603 Infrared Thermometer is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the Model PG-IRT1603 Infrared Thermometer can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Model PG-IRT1603 Infrared Thermometer as recommended below, according to the maximum output power of the communications equipment.
