How does the thermometer shake on the dividing head at 30 degrees

summary

As I have a cold recently, I always cough, runny nose and have a fever. Last night I had a serious burn. My husband was very worried. He quickly took a thermometer to measure the temperature for me. Today, I'd like to talk with you about how the thermometer shakes at 30 degrees on the dividing head.

How does the thermometer shake on the dividing head at 30 degrees

First: before using it, hold the end that is not the mercury head and shake it. Just shake it to 30 degrees. When reading, hold both ends of the thermometer with both hands (don't pinch the mercury tank), keep it flat, and slowly rotate inward or outward. When the glass refracts the mercury bar, you can read the number clearly.

Second: before the measurement, observe the thermometer to be used, understand its range (measurement range) and graduation value (the temperature value corresponding to each small grid); when measuring, make the glass bubble of the thermometer fully contact with the measured body; read after the indication is stable; when reading, you should carefully look at the thermometer.

Third: the temperature of the human body should be estimated before measurement; according to the estimated temperature, choose a thermometer with appropriate range. The thermometer should be in the human body. It will take a while for the glass bubble to be completely immersed in the tested body. Wait for its indication to stabilize before reading. When reading, the line of sight should be level with the upper surface of the liquid column in the thermometer. The correct record of measurement results should have numbers and units.

matters needing attention

In fact, we are all familiar with thermometers, but few people can use thermometers correctly in life. Because the use of thermometers is the need for methods, in the use of thermometers, the first need to put the temperature to 30 degrees, which requires certain skills and methods.
