Calibration measures the performance of a machine or measuring equipment, and compares its performance to a set of established standards. Well calibrated equipment generally makes life easier for the people using any measuring equipment. The work they do has fewer errors and they are able to make faster, more accurate decisions. The need for accurate measurements extends to the calibration process. Whatever values one gets during the calibration process are considered to be the most accurate ones. The calibration process has to be done accurately. Most calibration problems arise when the service that is being used is a low quality one. Companies should always be as accurate as possible especially if the company is operating under strict international standards like the ISO 9000.
Calibration is basically comparison between various measurements and making sure that they are within an accepted limit or variation from a set standard. The set standards are arrived at from various measurements and experiments done across the word. The SI unit is one such standard that most scientists use in their daily measurements. When an instrument is calibrated, it is compared to many others, a factor of calibration called traceability. Calibration standards are getting stringent with time and technology, making scales and instruments more accurate. Read more about electrical calibrations, right here.
Calibration is important because there are many scientific values that are subject to the interpretation of different people. Color blind people might argue over a certain color until they have a set standard they can compare it to. Things like loudness or heaviness are subject to the tolerance and strength of different people. Some quantities depend on the prevailing environmental conditions like viscosity and thermal conductivity. Finding the boiling point would be difficult without accurate pressure calibration because it depends on atmospheric pressure. For people with different points of view and fro different locations to understand each other, there has to be a standard system of calibration. Navigate here to learn about the various types of calibration as well as electrical calibration.
Calibration is important in the manufacturing process. Not every state, country or location is self sufficient. They will require either raw materials for their processing needs or have to buy already processes products from their neighbors. The quantities of these products when they are received should correspond to the quantities of those people that import them. Every manufacturing industry depends on a constant system of measurement of say, weight, so that they may be able to do business together. A standard calibration system will be like a language or link among the different parties.
Research laboratories also do research on phenomena that are universal across the word. Natural phenomena like diseases are never always location specific. For people affected by the same things being researched on to understand research done in a different country, there has to be one system of calibration and measurement.
Calibration techniques vary from equipment to equipment and from industry to industry. Force equipment calibration is different from temperature calibration and so on. Also, in some industries, the need for accuracy is greater than in others. Sometimes, different countries have different accuracy standards than others.
