How to Reset A Digital Thermometer


Thinking about calibrating your digital thermometer to make it more reliable? To learn more about it, stay with us as we discuss how to reset a digital thermometer.

According to the official digital thermometer calibration standards of the International Dairy-Deli-Bakery Association (IDDBA), there are two ways proven effective for this. Let’s discuss each.

The Ice-Point Method

This method tests a digital thermometer in freezing temperatures. Take note of the following steps:

  • Pour cold water into a glass and add crushed ice.
  • Next, dip your digital thermometer’s probe until it reaches the center part of the water. Make sure it won’t touch any surface of the glass.
  • Then, move your digital thermometer in small circles to gently stir the water. Wait for its temperature indicator to become stable.
  • See if the temperature is 32 degrees Fahrenheit or 0 degrees Celsius. If not, push the thermometer’s reset button without removing it from the water.
  • Adjust until you get the temperature right.

The Boiling-Point Method

The steps below outlines how you can do the Boiling-Point Method.

  • Boil distilled water in a pan. Do it until it reaches a rolling boil.
  • Dip the probe until it reaches the center of the boiling water. Make sure it won’t make contact with any part of the pan.
  • Don’t remove the pan from the heat. You may wear mittens to cover your hands from the steam.
  • Wait for the temperature indicator to stabilize.
  • Check if the reading shows 212 degrees Fahrenheit or 100 degrees Celsius. If not, push the reset button.
  • Keep adjusting the thermometer without removing it from boiling water until you get the reading right.
