4. How to Measure Body Temperature
The ADC® 424 Digital Ear Thermometer measures the heat 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 body 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:
• Use ONLY ADC® probe covers, as this unit is calibrated to work with probe covers.
• Straighten the ear canal by gently pulling the middle of the ear back and up. This en-
sures measurement of heat from the eardrum. (Please note: Pull outer ear out for new-
borns - age 1)
• Place the probe firmly into the ear canal. Press the Start button and keep the probe in the
ear until the thermometer beeps to indicate completion of the measurement.
• The 424 Digital Ear Thermometer has been clinically tested and proven to be safe and
accurate when used in accordance with operating instructions.
