16. Temperature taking tips
1)It is important to know each individual's normal temperature when they are well. This is
the only way to accurately diagnose a fever. Record readings twice a day (early morning
and late afternoon). Take the average of the two temperatures to calculate normal oral
equivalent temperature. Always take the temperature in the same location, since the
temperature readings may vary from different locations on the forehead.
2)A child's normal temperature can be as high as 37.7°C (99.9°F) or as low as 36.11°C
(97.0°F).
Please note that this unit reads 0.5ºC (0.9°F) lower than a rectal digital thermometer.
3)External factors may influence ear temperatures, including when an individual has:
– been lying on one ear or the other
– had their ears covered
– been exposed to very hot or very cold temperatures
– been recently swimming or bathing
In these cases, remove the individual from the situation and wait 20 minutes prior to taking
a temperature.
Use the untreated ear if prescription ear drops or other ear medications have been placed
in the ear canal.
4)Holding the thermometer for too long in the hand before taking a measurement can
cause the device to warm up. This means the measurement could be incorrect.
5)Patients and the thermometer should stay in steady-state room condition for at least 30
minutes.
6)Before placing the thermometer sensor onto the forehead, remove dirt, hair, or sweat
from the forehead area. Wait 10 minutes after cleaning before taking measurement.
7)Use an alcohol swab to carefully clean the sensor and wait for 5 minutes before taking a
measurement on another patient. Wiping the forehead with a warm or cool cloth may
impact your reading. It is advised to wait 10 minutes before taking a reading.
8)In the following situations it is recommended that 3-5 temperatures in the same location
be taken and the highest one taken as the reading:
• Newborn infants in the first 100 days.
• Children under three years of age with a compromised immune system and for whom
the presence or absence of fever is critical.
• When the user is learning how to use the thermometer for the first time until he/she has
familiarized himself/herself with the instrument and obtains consistent readings.
17. Care and cleaning
Use an alcohol swab or cotton swab moistened with 95%
alcohol to clean the thermometer casing and the measuring
probe. After the alcohol has completely dried out, you can
take a new measurement.
Ensure that no liquid enters the interior of the thermometer.
Never use abrasive cleaning agents, thinners or benzene for
cleaning and never immerse the instrument in water or other
cleaning liquids. Take care not to scratch the surface of the
LCD screen.
