What is indicated by the beep from a thermometer?

The beep from a thermometer signifies that it has finished measuring the temperature. This audible alert indicates to the user that they can check the reading, ensuring that they don’t have to watch the display continuously while waiting for the measurement to complete. Many modern thermometers come equipped with this feature to enhance user convenience and accuracy, making it clear when the data is ready to be interpreted.

Other options such as the need for replacement or calibration do not directly relate to the function of the beep; rather, they concern the maintenance and operational status of the thermometer, which is a separate aspect of its use. The beep specifically serves the purpose of indicating the completion of a temperature measurement cycle.
