How does Braun ThermoScan work?
Braun ThermoScan measures the infrared heat generated by the
eardrum and surrounding tissues. To help avoid inaccurate temperature
measurements, the probe tip is warmed to a temperature close to that of the human
body. When the Braun ThermoScan is placed in the ear, it continuously monitors the
infrared energy. The measurement is finished and the result displayed when the
thermometer detects that an accurate temperature measurement has been taken.
Why measure in the ear?
The goal of thermometry is to measure core body temperature
temperature of the vital organs. Ear temperatures accurately reflect core body
temperature , since the eardrum shares blood supply with the temperature control
2
center in the brain , the hypothalamus. Therefore, changes in body temperature are
3
reflected sooner in the ear than at other sites. Axillary temperatures measure skin
temperature and may not be a reliable indicator of core body temperature. Oral
temperatures are influenced by drinking, eating and mouth breathing. Rectal
temperatures often lag behind changes in core body temperature and there is a risk of
cross-contamination.
How to use your Braun ThermoScan
1
Remove the thermometer from the protective case.
Push the Power button .
2
During an internal self-check, the display shows all segments.
Then the last temperature taken will be displayed for 5 seconds.

The lens filter indicator will blink to signal one is
needed.
To achieve accurate measurements, make sure a new,
clean lens filter is in place before each measurement.
Attach a new lens filter by pushing the thermometer
probe straight into the lens filter inside the box and
then pulling out.
Note: The Braun ThermoScan will not work unless a
lens filter is attached.

Select age with Age Precision ™ button as shown below.
Press button to toggle through each age group.
NOTE: You must select an age in order to take a measurement.
The thermometer is ready to take a temperature when the display looks like the images
below.
Fit the probe snuggly into the ear canal, then push
5
and release the Start button .
ExacTemp light will pulse while temperature measurement is in progress. The
6
light will remain solid for 3 seconds to indicate that a successful temperature
reading has been achieved.
NOTE: If the probe has been properly inserted into the ear canal during the
measurement, a long beep will sound to signal the completed measurement.
If the probe has NOT been constantly placed in a stable position in the ear
canal, a sequence of short beeps will sound, the ExacTemp light will go out
and the display will show an error message (POS = position error).
