Many people, students, engineers, and workers have questioned why instrument calibration is required?
In Fact, it increases the cost of maintenance, workload, and many other activities.
To understand this question well, let’s take one simple example…
Imagine, you have diabetes, and you have to go to the doctor for a monthly check-up. The doctor checked your diabetes with a digital sugar-test meter. And he found high sugar in your body. So, according to that, he prescribes medicine for you.
After a week the Doctor found that the instrument which he used to measure diabetes in patients was not displaying correct reading. It means all prescriptions given to patients could be wrong. So it would create problems for patients as well as doctors.
Let’s take the second one for a better understanding.
You go to a gold shop to purchase gold. And you buy 5 grams of gold. He weighs using a digital weighing balance and sells it to you. After a few days, he observed that the weighing machine was displaying the wrong reading and had an error of 10 mg. So, it is clear that the gold which you bought was not 5 grams. It is 10 mg less of it.
It may happen the same in industries also.
If the pressure gauge on 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.
To conclude, to avoid these problems calibrations are necessary for all instruments.
If the instrument is not calibrated, a person may suffer the loss of their health, money, or safety.
Different instruments have different methods of calibration.
In the process of calibration, Calibrators check specific parameters of their instruments with the standard kit.
For instance, weighing machines have their own standard weight, the thermometer has its own specific temperature kit, certain instruments verify by checking samples and comparing with ideal results.
There are lots of methods and techniques to calibrate instruments.
Generally, all calibration processes have to be done by specifically authorized companies. And after calibration if the instrument is working, find ok, they provide one certificate. Which is valid for a specific time period only. Or they suggest some parts or components be replaced.
From the above examples, we can conclude that calibration plays a vital role in the day to day activities. And plays an important role in quality control and of any product.
