Body temperature measurement
Normal body temperature is a “range“, not a single point, as temperature varies from person to person. A person’s temperature can rise with excessive clothing, hot weather or accelerated activity (such as crying or exercise). In order to observe these naturally occurring variations and determine the normal temperature range for each member of your family, practice taking temperatures on yourself and healthy family members at different times of the day to determine their
“baseline“ temperature. The normal range for ear temperatures taken with the Braun
ThermoScan Instant Thermometer is from
35.8°C (96.4°F) to 38.0°C (100.4°F) for all ages.
Normal body temperature also varies with age. We have the highest temperatures when we are younger. About our eleventh year, body temperature begins to decrease gradually. The elderly population has the lowest body temperatures. For your reference, the following chart shows normal ear temperature ranges by ages groups for the
Braun ThermoScan Instant Thermometer:
Normal Ear Temperature Range by Age
Years of Age
0 - 2
3 - 10
11 - 65
>65
Celsius
36.4°C - 38.0°C
36.1°C - 37.8°C
35.9°C - 37.6°C
35.8°C - 37.5°C
Fahrenheit
97.5°F - 100.4°F
97.0°F - 100.0°F
96.6°F - 99.7°F
96.4°F - 99.5°F
When consulting your physician about fever, remember to communicate that this is an ear temperature, referrring to the appropriate ear temperature range in the chart above. Also, note the individual’s “baseline“ temperature as an additional reference point.
1. Remove the thermometer from its storage cover. If stored properly, a new lens filter will already be in place. (See procedure on page 7.)
Do not use thermometer without lens filter attached.
2. Depress the on-button that is located directly below the LCD (liquid crystal display) to turn the power on. (See Figure 1)
• All segments on the LCD-display (Figure
6) will be shown for two seconds to indicate a fully functional display.
• The display will indicate (not ready) while the unit is completing self test, then, within two seconds (ready) indicating that the thermometer is ready to take a temperature (Figure 7). If no temperature is taken within two minutes, the thermometer will automatically shut off.
3. Stabilise the head. In infants, this is best achieved by laying them flat with the head rotated so the ear is up.

4. Perform an ear tug and position the thermometer. In order to take an accurate temperature, the thermometer must be positioned correctly in the ear. In addition, an “ear canal straightening“ technique must be used to straighten the natural bend of the canal and ensure that the thermometer has a clear view of the eardrum.
• If you are right handed, hold the thermometer in the right hand and take the temperature in the right ear. If you are left handed, hold it in the left hand and use the left ear. This will help ensure proper placement.
• Perform an “ear tug“ by using your free hand to grasp the outer edge of the top half of the ear and follow the steps in the chart below. To take your own temperature, an ear tug is best achieved by wrapping your free hand around the back of your head and grasping your ear from behind.
Continue pulling the ear until you are finished taking the temperature.
