Throw the mercury column of the thermometer below 35℃ before use. Place the mercury end of the thermometer at the top of the armpit (that is, deep in the armpit), and clamp the thermometer with the upper arm to avoid dislocation or fall; measure for 5-10 minutes; take out the thermometer, read the temperature data, wipe the thermometer with toilet paper, So that it can be used next time or by others.
Reading method: Hold the tail of the thermometer with one hand, that is, the end away from the mercury column, keep the eye and the thermometer at the same level, and then slowly turn the thermometer to read the corresponding temperature when you see the thick mercury column from the front. Be careful not to touch the mercury end of the thermometer with your hand when reading, as this will affect the mercury column and cause inaccurate measurement.
