Switch on the digital thermometer before putting it near the mouth to make sure that it is working properly. The LCD screen should read “0” when it is initially switched on.

If this does not occur or the screen remains blank, you may find that the battery needs to be replaced.

Check the instruction manual to ensure that you get the correct replacement battery and that you fit it correctly. Only use the thermometer if the starting reading is correct.

Types of Thermometers

You have the choice of digital or manual (mercury) thermometers for taking a temperature in three ways:

Oral
Rectal
Axillary (armpit)

Two other types of digital-only thermometers are available:

Tympanic (ear)
Temporal (forehead)

Oral Thermometer Use

Oral thermometers are not the best option for young children, who may not be able to keep their mouths closed long enough to get a good reading.

To Use an Oral Thermometer

Wash your hands before handling the thermometer.

Place it under the tongue.

Make sure the mouth stays closed the entire time.

Wait approximately five minutes (manual thermometer) or for the beep (digital thermometer).
Don’t take an oral temperature right after eating or drinking something; it will affect the results.

Axillary Thermometer Use

While this is the least accurate way to get a child’s temperature, it’s often used in schools and daycare to avoid spreading germs.
To use an axillary thermometer: Place the thermometer under the arm with the tip in the deepest crease of the armpit.

Wait approximately five minutes (manual thermometer) or for the beep (digital thermometer).

Rectal Thermometer Use

Rectal thermometers are specifically designed with short tips that allow them to get a proper reading without going too far into the body.

This method should be used for infants or those whose temperature can’t be taken the other way.

To Use a Rectal Thermometer

Use lubrication, such as petroleum jelly, to ease insertion.

Place the thermometer’s tip in the rectum.

Wait approximately five minutes (manual thermometer) or for the beep (digital thermometer).

Cleaning Your Thermometer

Wash your thermometer before and after use with cold water, then lotion. Rinse thoroughly to remove the alcohol.

Tympanic Thermometer Use

These in-the-ear thermometers are very popular, especially among parents of small children, since they’re faster than regular digital thermometers and are easy to use.

However, tympanic thermometers can be difficult to use on babies and are often inaccurate because their ear canals are so small.

To Use a Tympanic Thermometer


Pull the top of earlobe up and back
Place the tip of the thermometer (covered with probe cover) in the ear canal opening. (Be sure you are pointing the probe into the ear canal opening and not at the wall of the ear.)
Press the button until it beeps.
Make sure excess earwax isn’t built up before using this method, as it can cause less accurate results.
