II. Intended use
The device is an infrared thermometer intended to measure forehead temperature of infants and adults without contacting human body. It can be used by consumers in
household environment and doctor in clinic as reference.
III. Introduction
The JXB-311 Non-contact Infrared thermometer has been developed by using the latest infrared technology. This technology allows temporal artery (TA) temperature to
be taken at a distance of about 0cm~3cm away from the forehead. Precise, Instantaneous and without Contact, the JXB-311 is, up to now, the most suitable thermometer
for no risk on temperature measurement. It has been demonstrated that this method of TA temperature measurement is more precise than the tympanic thermometry
and better tolerated than rectal thermometry (1). However, as with other types of thermometer, it is essential to use the JXB-311 properly in order to obtain reliable and
stable results. You are therefore advised to read this instruction manual and the safety precautions carefully before use. (1)Greenes D, Fleisher G. Accuracy of a Noninvasive
Temporal Artery Thermometer for Use in Infants. Arch Pediatr Adolesc Med 2001;155:376.
IV. Precautions before use
The JXB-311 is pre-set at the factory. It is not necessary to calibrate the device when starting it up. In order to obtain reliable and stable results, you are advised each time
there is a signicant change in the ambient temperature due to a change in environment, to allow the JXB-311 to acclimatize to this ambient temperature for 15 to 20
minutes before using it. It is important to allow 3~5 seconds interval between two measurements.
V. Operating principle
All objects, solid, liquid or gas, emit energy by radiation. The intensity of this energy depends on the temperature of the object.The JXB-311 infrared thermometer is
therefore able to measure the temperature of a person by the energy the person emits. This measurement can be taken thanks to anexternal temperature probe on the
device which permanently analyses and registers the ambient temperature. Therefore, as soon as the operator holds the thermometer near the body and activates the
radiation sensor, the measurement is taken instantly by detection of the infrared heat generated by the arterial blood ow. Body heat can therefore be measured without
any interference from the heat of the surrounding environment.
THE DIFFERENT METHODS OF TEMPERATURE MEASUREMENT
Core temperature
Core temperature is the most precise measurement and involves measuring the temperature in the pulmonary artery by means of a catheter equipped with a thermal
probe which can read the temperature in situation. The same method is employed for probes measuring the oesophageal temperature. However, such invasive
temperature measurement methods require specic equipment and expertise.
Rectal thermometry
Rectal temperature adjusts slowly in comparison to the evolution of the body’s internal temperature. It has been demonstrated that rectal temperature remains raised
long after the internal temperature of the patient has started to drop and vice versa. Furthermore, rectal perforations have been known to occur as a result of this method
and without appropriate sterilisation techniques, rectal thermometry can spread germs often found in faeces.

Oral thermometry
Oral temperature is easily inuenced by recent ingestion of food or drinks and by breathing through the mouth. To measure oral temperature, the mouth must remain
closed and the tongue lowered for three to four minutes which is a dicult task for young children to accomplish.
Axillary (armpit) temperature
Although it may be easy to measure axillary temperature, it has been proven that it does not provide an accurate measurement of the child’s internal temperature. To take
this type of temperature, the thermometer must be wedged tightly over the axillary artery. Despite the low sensitivity and relative inaccuracy of axillary temperature in
detecting fever, this method is recommended by The American Academy of Pediatrics as a screening test for fever in newborns.
Tympanic thermometry
In order to obtain a precise temperature reading, good command of the measurement technique is required. The thermometer probe must be placed as close as possible
to the warmest part of the external ear canal.
Normal temperatures according to measurement method
MEASUREMENT METHOD NORMAL TEMP°
RECTAL 36.6°C ~ 38°C
ORAL 35.5°C ~ 37.5°C
AXILLARY 34.7°C ~ 37.3°C
AURICULAY 35.8°C ~ 38°C
TEMPORAL 35.8°C ~ 37.8°C
The temperature of the human body varies throughout the day. It can also be inuenced by numerous external factors: age, sex, type and thickness of skin…
Advantages of temporal artery (ta) temperature
Infrared arterial temperature can be measured using a device placed on the forehead, in the temporal artery region. It has been demonstrated that this relatively new
method of measuring temperature is more precise than tympanic thermometry and better tolerated than rectal thermometry. The JXB-311 thermometer has been
designed to produce an instant forehead temperature reading without any contact with the temporal artery. As this artery is quite close to thesurface of this skin and
therefore accessible and given the blood ow is permanent and regular, it allows precise measurement of the temperature. This artery is linked to the heart by the carotid
artery which is directly linked to the aorta. It forms part of the main trunk of the arterial system. The eciency, speed and comfort of taking a temperature from this area
make it ideal compared with other temperature measurements methods.

Practical considerations when taking a temperature
• In order to ensure that precise and accurate temperature measurements are obtained, it is essential that each user has received adequate information on and training
in the temperature measurement technique when using such a device.
• It is essential to remember that although procedures such as taking a temperature may be simple they must not be trivialised.
• Temperature should be taken in a neutral context. The patient must not have undertaken vigorous physical activity prior to taking his/her temperature and the room
temperature must be moderate.
• Be aware of physiological variations in temperature which must be taken into consideration when evaluating the results: temperature increases by 0.5°C between 6
am and 3 pm. Women have a temperature that is higher, on average, by around 0.2°C. Their temperature also varies in accordance with their ovarian cycle. It rises by
0.5°C in the second half of the cycle and at the early stages of pregnancy.
• When sitting, temperature is lower by about 0.3°C to 0.4°C than when standing.
How to take a temperature
Aim at the FOREHEAD, over the right temporal region, from a distance of about °Cm~3cm, press the thermometer’s measurement button and the temperature
is instantly displayed. The reliability of the measurement cannot be guaranteed if the temperature is measured over another part of the body (e.g.arm, torso…)
Constraints
Please observe the following before any temperature measurement to ensure a stable and reliable result:
• Push back hair from the forehead.
• Wipe away any perspiration from the forehead.
• Avoid any drafts (e.g. from nasal specs, air conditioning…)
• Allow a 3~5 seconds interval between two measurements.
• Each time there is a signicant change in the ambient temperature due to a change in environment, to allow the JXB-311 to acclimatise to this ambient temperature
for at least 15 minutes before using it.

The temperature is in Fahrenheit. Change the measurement to Celsius.
THE SCREEN DISPLAYS TEMPERATURE LOWER THAN 32°C (89.6°F):
To take the surface temperature, press the “BODY” button and set to the reading called “Body” , If the device is in Surface Temp Mode, the 32°C
(89.6°F) temperature displayed is showing the external temperature of your body, rather than the internal.
THE SCREEN DISPLAYS THE MESSAGE HI
When using the JXB-311 Thermometer, the message “HI” can show on the screen. In this case,the temperature is above the measurement range selected, either above
43.0 °C (109.4°F) in Body Mode.
