Lumiscope DELUXE 2215 User Manual

The tympanic membrane (eardrum), and 

the hypothalamus (the part of the brain 

which controls body temperature) share 

a common blood supply, so tympanic 

readings rise and fall rapidly with core 

temperature (deep-body temperature). 

This makes ear temperature one of the 

best indicators of internal body (core) 

temperature.
What are normal temperature values?

Human body temperature varies from 

person to person, and body temperature 

fluctuates throughout the day. Because of 

this natural variation, you should become 

familiar with your normal body tempera-

ture range by measuring it yourself when 

healthy, in order to establish reference 

temperatures which will make you feel 

more confident of the measured tempera-

ture when it is abnormal.

1. Try the 2215 Ear Thermometer on 

yourself first to become familiar with its 

operation.

2. Taking the temperature immediately 

after waking up may cause the reading 

to be higher than normal as a result of 

sleeping on the ear.

3  It is common for the right and left ear 

readings to be slightly different; use 

the same ear consistently to obtain 

temperature readings.

4. Straighten the ear canal before and 

during measurements:

For Children under 12 months:

Straighten the ear canal by pulling the ear 

back as shown below.

For Children over 12 months and Adults:

Straighten the ear canal by pulling the ear 

back and up as shown below.

5. This ear thermometer automatically 

converts measured ear temperature 

reading to oral temperature.
