How to Use a Walgreens Digital Thermometer

Although mercury thermometers have been used and trusted by doctors and parents for years, their digital counterparts make measuring a temperature much faster. If you or your child is ill, the quick and accurate readings provided by the Walgreens digital thermometer will help you decide whether it's time for a visit to the doctor 1.

Open the battery cover near the bottom of the thermometer handle. Insert a CR2032 battery with the positive (+) end facing up. Replace the cover.

Place a fresh probe cover over the tip of the thermometer. If you are using the oral model, slip the plastic sheath over the metal-tipped end of the thermometer. For the Deluxe Instant Ear model, place a fresh cover into the hole in the storage case. Push the tip of the thermometer into the hole until you hear a slight click -- this means the cover has been fitted correctly.

Press the "ON/OFF" button in the middle of the handle. Wait until the small screen near the top of the handle clears before taking a measurement.

Insert the tip of the thermometer into an orifice. For the oral model, place the covered tip under the tongue and close the mouth around it. For the Deluxe Instant Ear model, lift the outer ear up and back and insert the probe snugly into the ear canal. Press the small "START" button near the tip of the thermometer.

Wait for the thermometer to beep. Gently remove it from the mouth or ear canal and read the temperature displayed on the small screen.

Remove the used probe cover and discard it. Press the "ON/OFF" button to power the thermometer off.
