What is Calibration and Why is it Important

What is Calibration?

Imagine a watch with seconds pointer that takes longer than a second to tick; it means the watch will not show the correct time and defeat its purpose altogether. In such a scenario, the watch would need to undergo a correction in its instrument setting. Simply putting it, once the seconds pointer is repaired or corrected the watch starts showing correct time. Applying the same concept to an industrial instrument and its subsequent repair is known as calibrating the instrument. Therefore, Calibration is the setting or correcting of a measuring device or base level, usually by adjusting it to match or conform to a dependably known and unvarying measure. The calibration process generally involves using the instrument to test samples of one or more known values called `calibrators; just like any equipment that may be used to repair a watch.

Why is Calibration important?

Instrument Calibration is a necessary and important part of any instrument system for the control and safety of other instruments, instrument calibration becomes of foremost importance.

How is Calibration Done?

To understand calibration process, we need to first understand that most instruments do not work in isolation. They work together in a cluster, also known as "loop" in industry parlance. So calibration essentially means calibrating instruments in a loop. Because of complicated interconnection, loops frequently undergo drift which requires their calibration.

If you want to calibrate instruments in a loop there are two ways of going about it - you can either calibrate each of the instruments individually (known as individual calibration) or you can calibrate the loop as a whole (known as loop calibration).

Individual calibration is one of the earliest known methodologies. This essentially means removing the instruments from their loop and individually calibrating them, although one of the best known methods, this is time consuming and can lead to errors in connections.

Loop calibration is, therefore, a more reliable method. A loop calibration is a set of instruments that are grouped and calibrated together. The input and output of the whole group determines the pass or fail status of the calibration. This means, if there is an error in one it will lead to a domino effect of errors on all other instruments that are part of the loop. Loop calibrator thus requires a special kind of calibrator, known as loop calibrator, that is equipped to handle and effectively calibrate instruments in loop. Loop calibrators, can again, be portable (i.e. handheld) or stationary. Portable calibrators are more popular, obviously because they are more convenient to use.


Individual calibration is also not very effective in measuring long time drifts, whereas a device that can handle loop calibration will generally enable measuring long time drifts which is less time consuming and ensures higher accuracy.

Choose The Right Calibration Services

The intense increase in the use of various electronic gadgets has simplified the way of life of people. There are so many tasks which are performed with the help of various gadgets. This has greatly reduced the manual efforts and incorporated an element of modernization. Various gadgets have found application in different households, industries and factories. The use of various modern devices has made it possible for individuals and establishments to get several benefits. However, it is extremely important for people to ensure that the gadgets they use are at par with certain standards. A gadget which is performing below a standard is not considered to be very suitable.

One very important thing which gadget users should keep in mind is about calibration. There are a number of experts who provide these services. Calibration services are basically the methods of evaluating and adjusting the values of a gadget for its precision and accuracy. Such a thing is done by comparing the gadget with another gadget which has an accurate and unvarying standard. These services are capable of checking, determining and correcting all the gadgets that use quantitative measurements. Many individuals and establishments rely greatly on these services. The method of calibration cannot accept any kind of faulty and shortcut processes. These services include validation, repair, preventive maintenance and electronic asset management.

Many laboratories, hospitals, measuring device manufacturers, aviation and testing industries, engineering institutions and processing plants undergo calibration. In order to ease the process, calibration instruments can be used. The use of these instruments brings a number of benefits. It can greatly benefit the manufacturers and consumers. Manufacturers can greatly increase their level of productivity, get a smooth flow of work and reduces wastage. The consumers will get the advantage of using high quality products. The business organization as a whole tends to become very credible by using these instruments. wastage Their brand becomes popular throughout and is promoted positively. The instruments should definitely be calibrated in these establishments so that the standards are maintained and the progress of the establishment is ensured.

Organizations should make all possible efforts to avail these services from a reliable source. If a reliable and expert service provider is approached for carrying out the process of calibration, the establishments can get several benefits. These service providers use sophisticated instruments for the process. They are capable of giving the accurate results. Proper actions can then be taken by the establishment. These services can be adopted at extremely reasonable costs. There is no need to spend huge sums of money in getting the instruments calibrated. The reliable services would ensure cost effectiveness to the establishments. It proves very profitable for the organization, individuals and households to a great extent.
