How This Thermometer Measures Ear Temperature - Microlife IR 1DE1 Instruction Manual

4. How this Thermometer Measures Ear Temperature

This thermometer measures infrared energy radiated from the eardrum
and the surrounding tissue. This energy is collected through the lens
and converted to a temperature value. The measured reading obtained
directly from the eardrum (Tympanic Membrane) can ensure the most
accurate ear temperature.
Measurements taken from the surrounding tissue of the ear canal
generate lower readings and may result in misdiagnosis of a fever.
To avoid an inaccurate measurement:
• Switch on the thermometer by pressing the O/I button.
• After one beep is heard (and the temperature scale icon is flas-
hing), straighten the ear canal by gently pulling the middle of the
ear back and up.
• Place the probe firmly into the ear canal, press the START button
and keep the probe in the ear until the thermometer beeps to
identify the completion of the measurement.
This thermometer has been clinically tested and proven to be
safe and accurate when used in accordance with its operating
instruction manual.
