Final answer:
The dimple of a thermometer is the spacing between the markings on its scale, and it cannot be adjusted during calibration. It should not touch meat, poultry, or fish. The dimple is not made up of liquid crystals.
Step-by-step explanation:
The dimple of a thermometer is not the marking that indicates the depth of insertion required. The dimple is actually the spacing between the markings on the thermometer's scale. It helps the user to accurately read the temperature and determine the depth of insertion required.
The dimple of a thermometer cannot be adjusted during calibration. It is a fixed feature of the thermometer and is designed to provide consistent and accurate temperature measurements.
The dimple is not made up of liquid crystals. Liquid crystals are used in some types of thermometers, such as digital thermometers, but they do not make up the dimple.
It is important to note that the dimple of a thermometer should not touch meat, poultry, or fish, as it can contaminate the food and affect the accuracy of the temperature reading.
