If you want to check your fever, a digital thermometer is a great tool to have. These devices are easy to use and give precise readings. If you don’t know how to use a digital thermometer, follow these steps. 

Step 1: Reset The Thermometer

If you have an oral thermometer, you may need to reset it before using it. It’s a very simple process that will ensure that your thermometer stays accurate for the long term. There is a reset button on the device, which you need to press. 

Step 2: Place The Thermometer Under The Tongue

Using a thermometer is one of the easiest and most effective ways to get a quick and accurate reading of body temperature. Once you reset the digital thermometer, you need to place it under the tongue to measure temperature. To take an oral temperature, place the tip under your tongue toward the back of your mouth. Make sure that you do not bite it and breathe normally through your nose.

Step 3: Close Mouth Around Thermometer

If you’re using a thermometer to check your temperature, it is important that you close your mouth around it. If you open your mouth, air can get in the way of the readings and make them inaccurate. Hold your lips tight over the tip and wait for it to beep.

Step 4: Leave In Place Until You Hear The Beep

Next, you need to wait for the beep sound before you remove the digital thermometer from your mouth. A large display digital thermometer beeps when the temperature is recorded. It takes only a few seconds or minutes to check the temperature with a digital thermometer.

Step 5: Read The Level Shown On The Digital Display

Now, you can read the temperature given on the LCD screen of the digital thermometer. If the temperature is above the normal range, it indicates fever. 

Step 6: Clean The Thermometer

It’s important to keep your digital thermometer clean because it can be easily contaminated with germs that can cause colds and other illnesses. Cleaning a water resistance digital thermometer before and after each use helps prevent the spread of these germs and ensures that you’re using a germ-free device when you measure someone’s temperature.


Taking your temperature is an important part of diagnosing your illness and monitoring how well you are recovering from it. Nowadays, most doctors use a digital thermometer because it is easy to use.
