How do I know if my digital thermometer is working?

For digital thermometers, use the cold water or boiling water procedure to test the thermometer every six months or so (depending on frequency of usage). Reset buttons are found on many digital thermometers. If the thermometer's accuracy is off, use this button to adjust it to the correct temperature.

For oral thermometers, use the same procedure once a month. Oral thermometers should not be used for more than one month without calibration because the device itself starts to drift after this time.

Oral thermometers work by detecting your body heat which changes depending on how you are doing health-wise. As your body heats up, so does the surrounding air. The oral thermometer detects these fluctuations in temperature and displays what type of fever you have. There are two types of oral thermometers: tympanic and rectal. Both work by detecting your body heat and displaying its degree over a certain period of time. However, they work using different methods and have different levels of sensitivity.

Tympanic thermometers look like headphones with a small bulb at each ear tip. They measure your body temperature by emitting sound waves into your ear canals and detecting the vibrations from your tympanic membrane, the membrane inside your ear canal that determines the temperature of your body. Because heat causes molecules to vibrate faster, measuring your body temperature by listening to the speed of those vibrations provides a reliable estimate of how hot you are.

Does a digital thermometer need to be calibrated?

Thermometers that are used often must be calibrated on a regular basis (weekly or monthly). To take temperatures, follow the manufacturer's instructions. Always calibrate a fresh thermometer, as well as one that has been dropped on a hard surface or has a temperature reading that is wrong by more than +/- 2 degrees Fahrenheit (+/-0.5 degrees Celsius).

How do you reset an electronic thermometer?

The ice point approach is the first reset method.

  1. Fill a glass with crushed ice.
  2. Add a little clean water until the glass is full and stir.
  3. Wait for about three minutes before inserting the sensor on the thermometer into the ice-filled water.
  4. Wait for about thirty seconds and check that the thermometer reads 32°F.

Do we need to calibrate the thermometer before using it?

If you drop a thermometer, you should calibrate it right away. When a thermometer is subjected to a broad range of temperatures (from freezing to boiling), it should be calibrated more regularly. When you buy a new thermometer, make sure to calibrate it before using it. You can calibrate a thermometer by dropping it into water and noting the temperature displayed on the thermometer's screen.

The thermometer should read exactly 100 degrees when placed in the water. If it does not, then recalibrate it. Recalibration can be done at any time after installation with no effect on the accuracy of the thermometer.

Recalibration can be done in water or another liquid of known temperature. It is recommended that you recheck your calibration result periodically to ensure that the thermometer is still giving accurate readings.

Here are some things to remember when using thermometers:

Thermometers must be maintained properly to give reliable readings. Clean thermometers accurately record temperature differences between objects that differ in size or location within a house. This means that they need to be cleaned regularly with warm, soapy water and dried immediately after use.

Dropping a thermometer onto hard surfaces such as tiles or concrete may damage it. These surfaces could lead to cracks that would show up as missing data when recording temperatures.
