Answer: The possible reasons are:
1) The measurement distance was too far, the thermometer was actually
testing the surrounding environment. Under body temperature mode,
the measuring distance designed is 1-3 cm, and the optimal distance is
about 1 cm.
2) The thermometer might be pointing at the wrong position. When
measuring body temperature, aim the thermometer at the center of the
forehead (above the eyebrow) and keep it perpendicular to the forehead.
3) When the person under test has hair covered the forehead, sweat or
water on the forehead, had ice compress or cooling stickers or have
taken antipyretics, the forehead is blown by strong wind, etc, it may
appear "Lo“. It is required the person being tested to stay still in a
relatively static environment for 5 to 10 minutes before taking
measurements.
4) There are very few people whose forehead surface temperature is lower
than average. In such cases, the test result may be "Lo". You can adjust
the thermometer to “object temperature" mode to measure, and then
test the surface temperature of other people's forehead for comparison.
5) The F1-temperature overall offset setting parameter is incorrect. Try to
correct it or reset it to default, please refer to the operating manual for
the procedure.
Q2: When I first used it to measure body temperature, I had doubt in the
readings. Why’s that and what can I do?
Answer: When you first use the thermometer, please pay attention to the
following things:
1) Check if the temperature measurement mode is set to the object
temperature mode, if it is the object temperature mode, please switch to
the body temperature mode.
2) Place the thermometer in a stable room temperature environment for at
least 30 minutes.
3) Sometimes smudgy/dirty lens of the sensor or sweat on the forehead
leads to low readings, make sure the lens is intact and the forehead is dry
before measurement.
4) If you think the reading is too high, observe the person that has been
measured, usually if a person just exercised, for example, fast walk or run,
or the person has just finished a meal or came from hot environment, it is
likely the body temperature is higher, kindly ask the person to stay indoor
for a while till his/her conditions return to normal, then measure again.
5) Some people might have unique physical characteristics such that the
forehead temperature is lower than average. Use a traditional mercury
thermometer or clinical electronic thermometer to measure someone
who you are sure that he/she is in healthy conditions, assume you then
get a body temperature reading of 36.8℃. Use an infrared thermometer
to measure the same person, pay attention to the test distance and test
method: keep the distance between the thermometer and the forehead
between 1 and 3 cm, and remove any obstacles that may affect the
measurement, such as hair and sweat. If you get the same temperature of
36.8℃ , it means that the thermometer is working normally and can be
used normally. If you get a reading lower than 36.4℃, say the difference
is 0.4 ℃ . You can switch to F1 mode and set the offset to +0.4 ℃ , vice
versa.
