When the user installs new batteries and gets readings thought to be inaccurate, please check the following:
How old is the battery? Batteries loose capacity over time even if not used.
Please ensure the battery is new.
A battery may work with other devices (alarm clock for example) that have a lower minimum required input voltage but may not work with the thermometer.
Q.What is the lifetime of the TempTeller ear thermometer? A. TempTeller products are designed for a long product life. Components used are of high quality and carefully protected. In spite of careful design & construction, abuse of the TempTeller Thermometer can result in product failure.
When designing a new product we perform stress tests of key components to ensure long-life. Our product is designed to last for 5 to 10 years under estimated 'normal' home use conditions.
Proper care and use of the Microlife Thermometer should ensure many years of accurate temperature measurements.
Q.Does room temperature affect readings? A. No, as long as the operating temperature is between 10C and 40C (50F and 104F)! If the thermometer itself is outside this range no measurements can be performed. The display shows "L" or "H". It may take some time before the thermometer reaches its operating conditions.
Please note the position of the probe tip during measurement can have an influence on the results. It is very important to straighten the ear canal and insert the probe tip comfortably and completely in the ear canal to ensure accuracy.
Q.Which ear should you use to measure body temperature? A. Generally, there are no significant differences in ear temperatures. We recommended you practice measuring temperature when well, determine normal temperatures for you and your family, and use the ear that gives you a higher reading.
Use an alcohol swab or a cotton swab moistened with alcohol (70% isopropyl, available in the pharmacy) to clean the thermometer casing and the measuring probe. Ensure that no liquid enters the interior of the thermometer. Never use abrasive cleaning agents, thinners, gasoline or benzene for cleaning. Never immerse the instrument in water or other cleaning liquids. Take care not to scratch the surface of the display.
The TempTeller Ear Thermometer is manufactured to meet the same international standards as hospital devices.
The difference to a hospital unit is the design. Hospital devices are more robust and thus less sensitive against falling down. They are delivered with solid wall brackets, comprehensive probe cover supply devices, etc.
Some professional thermometers offer the feature to display the results alternatively compared to rectal or oral readings. We think that this very confusing and we prefer to display the real, reliable ear temperature. Up to our knowledge, there is no medical basis which allows to "transfer" the data to rectal or oral results.
Rectal measurements are slightly higher then oral measurements.
An underarm measurement is most impacted by room temperature, so accuracy is more difficult to verify. Underarm measurements are lower then oral measurements.
Q.Can the probe cover remain on the tip after measurement? A. The probe cover should be removed after each measurement. Use of the thermometer without a cover can result in transmission of germs (unacceptable hygiene). A dirty probe cover can grow germs that can be passed to the next user.
Repeated use of the same probe cover results in a loose fitting cover, leading to inaccurate measurements.
In addition, use of the thermometer without a cover can result in transmission of germs. (unacceptable hygiene) Even a small amount of earwax on the probe tip allows bacteria and fungus to grow outside the ear!
Please use a new cover for each measurement.
The probe cover also protects the infrared sensor from earwax, which can destroy the sensor.
Q.Can the TempTeller infrared ear thermometer harm you in any way? A. No, TempTeller ear thermometers does not sending out any waves or heat at any time. It only acts as a receiver of heat. If the ear is inflamed or an ear infection is present, it is recommended the measurement be taken in the other ear or a standard digital thermometer should be used orally, underarm or rectally as appropriate.
Pull the ear as explained in the instruction manual and gently insert the probe into the ear. When you feel resistance from the ear, don't push any further and maintain the position.
Q.How does the TempTeller ear thermometer work? A. The TempTeller ear thermometer measures infrared energy radiated from the eardrum and the surrounding tissue. This energy is collected through the lens and converted to the correct temperature value.
Q.Why measure body temperature at the ear? A. TempTeller Ear Thermometers measure the infrared heat of the eardrum, which is very close to the temperature control centre of the brain. This allows detection of changes of body temperature instantly compared with other common measuring instruments. Body temperature is measured safely and conveniently in only 1 second; for babies, children and adults of all ages.
