1. Summary of infrared
thermometer
Thank you for choosing our Infrared
Thermometer. The MDI231 Infrared
Thermometer is used to measure an
objects temperature based on the re-
lationship between temperature and
measurable infrared radiation. Sim-
ply aim the unit’s probe toward the
surface to be measured to obtain a
quick and accurate temperature. To
ensure proper use, please be sure
to read this user manual carefully,
paying close attention to the safety
precautions.
• In order to use this product correct-
ly, please read the user manual be-
fore use.
• In order to properly use this pro-
duct, please carefully read the full
text of this manual before using, in
particular the “safety precautions”
section.
• Please keep the instructions on the
side for easy checking.
Basic principles:
All objects above absolute zero tem-
perature emit certain percentage of
infrared radiation energy based on
its temperature. The amount of the
radiation energy and the distribution
of the wavelength have very close
relationship. When human body tem-
perature in 36-37°C, it emits wave-
length 9-13um of infrared radiation.
Based on this principle, according
4
to the relationship between surface
forehead temperature and eardrum
of ear temperature, we are able to
measure the human body actual tem-
perature.
2. Safety precautions
Warning !
• Use of this thermometer is not
intended as a substitute for con-
sultation with your physician. It is
dangerous for user to perform a
self-evaluation and self-treatment
based on the measuring result. Be
sure to follow doctor’s instruction.
• Keep the thermometer out of reach
of children. For accidental swal-
low of battery or other component,
please consult the doctor at once.
• The patient who suffer the external
otitis and media otitis or other ear
disease that will be prohibited to
using the product to measure ear
temperature. It may worsen the les-
ion.
• Don’t throw the battery into re.
Notice !
• The device is precision instrument,
don’t drop, tramp or impose any
vibration or impact on the thermo-
meter.
• Do not touch the lens of the probe
with your ngers, and do not dis-
semble the device by yourself.
• Before measuring forehead tempe-
rature, make sure the hair removed,
5
sweat dried.
• After you do some exercise, eating
and bathing, you should stay still
indoor about 30 minutes before
measurement.
• To make the measurement data
reliable and stable, when ambient
temperature varies a lot, the ther-
mometer should be placed indoors
for about 30 minutes before using.
• When we measure somebody con-
tinuously, the temperature should
be measured every minute, if you
need to measure yourself conti-
nuously for a short time, there are
some slight errors when you read
the temperature, which is a nor-
mal phenomenon. At this time, we
should choose the average. We re-
commend that you measure your-
self continuously maximum of three
in a unit of time, and because the
temperature of the human will con-
duct to the thermometer, it may af-
fect the accuracy of measurement.
• There is no absolute standard about
the temperature of the human, so
please try to collect the recording of
individual temperature in the usual,
as a reference for having a fever or
not.
• Do not measure the sites of scar-
red tissue or tissue compromised
by skin disorders, because sen-
sing body temperature from sites of
scarred tissue or tissue compromi-
sed by skin disorders.
• Do not measure the site of forehead
temperature if that patients has
6
trauma on forehead.
• Do not measure if that patient is
treated with certain drug therapies.
• Do not immerse the device into wa-
ter or any other liquid, and not di-
rectly sunlight exposure.
• Do not use a mobile or cordless
phone near the thermometer when
measuring.
• Body temperature may increase in
the drug within the effort time limit.
Please don’t measure.
• In order to ensure the accuracy of
measurement data, please don’t
take measurement of body tem-
perature in strong electromagnetic
interference environment (such as
microwave, high frequency equip-
ment operation environment).
• Do not forcibly insert the probe in
the ear. If you fell abnormal such
as pain during measurement, stop
using the unit. It may injure the ex-
ternal auditory canal.
• If the ear is cooled such as being
exposed to the cold for a long peri-
od, wait until the ear is warmed up,
then measure. The measured result
may be indicated low when you use
an ice bag or immediately after co-
ming home from outside in winter.
• Do not use the unit to measurement
ear temperature when the external
auditory canal is wet such as after
swimming or a bath. It may cause
measurement inaccurate.
• Do not disassemble, repair, or mo-
dify the unit.
• This thermometer is only a perso-
7
nal device, please do not use with
others.
• Do not touch the battery output
when measuring.
• The thermometer must be stored
according to the technical speci-
cations.
• The materials (ABS) of expect con-
tact with patient had passed the
ISO 10993-5 and ISO 10993-10
standard test, no toxicity, allergy
and irritation reaction. They are
compliance with the MDD require-
ments. Based on the current scien-
ce and technology, other potential

aim at the eardrum.
NOTE:
1. Keep the probe surface clean, oth-
erwise the measurement can’t be
accurate.
18
2. Clean the probe with clean cloth or
paper moistened with water or al-
cohol, and conduct measurement
after the water on the surface of
the probe all evaporates.
TEMPERATURE TAKING HINTS
- The right ear temperature may differ
from the left ear. Therefore, always
take the temperature in the same
ear.
- The ear must be free from obstruc-
tion excess earwax build-up to take
an accurate reading.
- External factors may inuence ear
temperatures, including when an
individual has:
■ Been laying on ear or other
■ Had their ears covered
■ Been exposed to very hot or very
cold temperatures, or
■ Been recently swimming or bathing
- In these cases, remove the individ-
ual from the situation and wait 30
minutes prior to tacking a temper-
ature.
■ Use the untreated ear if prescrip-
tion ear drops or other ear medi-
cation have been placed in the ear
canal.
■ Don’t use the thermometer out-
doors.
9. Measure forehead temperature:
Install the temperature measuring
cap to switch to the forehead temper-
ature mode.
19
Press the On/Off key to turn on the
thermometer and proceed to 2s full-
screen display. Then the temperature
value of the previous measurement
will be displayed for 2s, and then
the thermometer will get into the
forehead temperature mode with a
“beep” sound. Aim the temperature
measuring probe at the forehead
and press the Measure key (if you
press and hold the Measure key, the
thermometer will keep scanning with
several “beep” sounds and then com-
plete the measurement when you re-
lease the Measure key) to perform a
measurement, and the temperature
value will be displayed on the screen
with a “beep” sound. Such temper-
ature value is displayed with green
(<37.5°C), orange (37.5°C ≤tem-
perature <38.0°C) or red (≤38.0°C)
backlight, as shown below.
NOTE:
Make sure the temperature measur-
ing probe aims at and touches the
forehead (between the eyebrows)
closely.
TEMPERATURE TAKING HINTS
- Before take the temperature, please
x the forehead hair to prevent
measured deviation.
