7. WHAT IS A “NORMAL” TEMPERATURE?
Although the generally accepted “normal” temperature
reading is 36.6˚C, temperature readings can vary from 35.2˚C
to 36.8˚C and still may be considered “normal”. Variations in
temperature can be attributed to activities such as exercise,
smoking, eating and drinking. Your temperature is lower in
the morning than in the afternoon.
Other variations may be due to the location of the tempera-
ture reading. While the axillary temperature follows the
guidelines previously described, an oral temperature is gen-
erally 0.5˚C higher. Rectal temperature will be 1.0˚C higher.
Infrared forehead temperature readings are equivalent to
oral temperature readings.
MEASURING METHODS NORM
Ear measurement 35,5 – 37,5
Forehead measurement 35,5 – 37,3
Tips for measuring human temperature
Bear in mind that the thermometer needs to have been in the
room in which the measurement is taken for at least
30 minutes before use.
NOTE:
• Some people produce different readings in their left and
right ear. In order to record temperature changes, always
measure a person’s temperature in the same ear.
• The ear thermometer may be used by children only under
adult supervision. Measurement is usually possible over

10
Instructions for use
En
WF-1000
the age of 6 months. In infants under 6 months, the ear
canal is still very narrow so the temperature of the ear-
drum often cannot be recorded and the result displayed
is often too low.
• The measurement must not be taken in an ear affected
by inflammatory diseases (e.g. discharging pus or secre-
tion), after possible ear injuries (e.g. eardrum damage) or
in the healing period after operative procedures. In all of
these cases, please consult your doctor.
• Use of the thermometer on different persons can be inap-
propriate in the event of certain acute infectious diseases
because of the possible spread of germs despite cleaning
and disinfection. If you have any doubts, please consult
your doctor.
• This thermometer may only be used without a disposable
protective cover.
• If you have been lying on one ear for some time, the tem-
perature is slightly raised. Wait a little while or measure
in the other ear.
• As ear wax can affect the measurement, you should clean
the ear before measuring if necessary.

8. HOW TO TAKE YOUR TEMPERATURE
To switch from ear scan mode to forehead scan mode,
simply take off the Cover cap. To switch from forehead scan
mode to ear scan mode, put on the Cover cap again. It is
recommended to use your thumb to pull from either side of
the Cover cap to remove it easily.
* When taking the forehead temperature, the reading is
provided for reference only because the condition of skin is
likely affected by the surroundings.
Measuring body temperature in the ear
1) Press the Power/ Scan button for 1 second to switch the
thermometer on. All symbols appear in the display at first.
The last temperature measured will appear.
As soon as the Ear measurement mode “ “ appears
in the display, the device is ready for use.
Following a successful self test, the device emits a beep.
2) Make sure that the sensor
tip and also the ear canal
are clean. As the ear canal
is slightly curved, you have
to pull the ear slightly up
and backwards before
inserting the sensor tip.

12
Instructions for use
En
WF-1000
This is important so that the sensor tip can be pointed
directly at the eardrum.
3) Insert the sensor tip into ear canal carefully and then
press the Power/Scan button for 1 second and release.
4) The end of the measuring time is signaled with a short
beep and the measured value appears on the display.
Measuring body temperature on the forehead
1) Please note that the forehead/temples must be free from
sweat and cosmetics and that taking medication and
skin irritations can distort the result when measuring
temperature on the forehead.
2) Make sure that the Forehead/Cover cap is put on. Press
the Power/Scan button for 1 second to switch the ther-
mometer on. Following a successful self test, the device
emits a beep.
3) Place the measuring head with the
Forehead/Cover cap fitted on the
temples, hold on the Power/Scan
button and move the thermometer
smoothly over the forehead to the
other temple.

4) Release the button. The end of the measuring time is sig-
nalled with a short beep and the measured value appears
on the display.
The screen displays “Lo” or “Hi” when the temperature
measured is out of the measurement range. (See Figure 1,
2, 3, 4)
The mark “Err” appears if the operating temperature is
NOT within 15°C (59°F) and 35°C (95°F). (see Figure 5)
