Why Calibration is Important?

Imagine, one day you go to a doctor for checking your blood pressure and after checking your blood pressure with a digital blood pressure monitor or sphygmomanometer, it is found that your blood pressure is high.

So the doctor prescribes medicine for high blood pressure. After a few days, it was observed that the machine itself was not displaying its reading properly. It means all given prescriptions given to patients could be wrong.

Imagine you went to the gold shop for buying gold. And ask for 10 grams of gold. He weighs using a Digital weighing balance and sold it to you. Some customers observed that the weighing balance is displaying the wrong readings.

Imagine the pressure gauge of the boiler is showing the wrong reading and you are standing beside it. It may burst due to high pressure and you never know because of the wrong display on the pressure gauge.

Imagine the temperature monitoring system of the Incubation chamber of babies is showing the wrong temperature. It will cost the lives of babies.

During the Ganesh festival, police uses the instrument sound level meter for measuring noise pollution. If the sound level meter is not calibrated it will show wrong readings and correspondingly wrong measures would be taken.
