Taking the temperature gives a measurement that provides information about a person’s current body temperature.
If you are uncertain about interpreting the results or if the value is abnormal, please consult your doctor. This also
applies in the case of slight temperature changes if there are other symptoms of illness such as agitation, severe
sweating, flushed skin, fast pulse rate, tendency to collapse, etc.
Temperatures measured with different thermometers cannot be compared with one another. You should therefore tell
your doctor (or bear in mind if you are diagnosing yourself) what thermometer you used to take your temperature and
in what part of the body.
The temperature of a healthy person is influenced by various factors: individual metabolic rate, which depends on the
person, age (body temperature of infants and small children is higher and decreases as they age). Greater tem-
perature fluctuations occur faster and more often in children, e.g. due to growth spurts), their clothing, the ambient
temperature, the time of day (body temperature is lower in the morning and increases throughout the day towards
evening), the preceding physical and, to a lesser extent, mental activity.
The temperature varies depending on the part of the body where the measurement is taken. The difference can be
between 0.4 °F (0.2°C) and 1.8 °F (1°C) for a healthy person. The normal temperature ranges are as follows:
• on the forehead: 96.4°F – 99.7°F (35.8°C – 37.6°C), with a forehead thermometer,
• in the ear: 96.8°F – 100°F (36.0°C – 37.8°C), with an ear thermometer,
• in the back passage: 97.3°F – 100°F (36.3°C – 37.8°C), with a conventional thermometer,
• in the mouth: 96.8°F – 99.3°F (36.0°C – 37.4°C), with a conventional thermometer.
In order to track temperature change, always take the measurements in the same part of the body.
7. Measuring
Before each use, please check that the lens is intact. If it is damaged, please contact your retailer or the service address.
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.
