When we talk of a calibration test, it is usually to denote a procedure where a device, tool or instrument is being tested to confirm that it conforms to the standards. It is necessary to calibrate measuring devices to ensure that the measurements are given correctly. There can be several reasons why a calibration test is run. Often, a measuring tool might not be working correctly or it needs to be checked and validated that it provides correct calibration before a concise measurement is required for it.
How calibration tests are conducted
In certain cases, people often run their own calibration tests. The accuracy of the scales of a grocery store needs to be checked every week. This is done by weighing an object whose weight is known from before. The scales are centered at zero and then the object is placed on the scale. The weights are tried in different ways to ensure the weighing of the scale is accurate. In case of a wooden growth chart the material might lengthen or shorten due to climatic conditions. For this, frequent calibration might be necessary.
How inaccuracies are corrected
When scales or other measuring tools are being calibrated, usually the scales are checked with an object whose weight is known. The same applies to wooden growth chart where the known height of a person or thing can be measured. The inaccuracy of a measuring device is corrected by repairing the device or adjusting the scales. In certain cases it might have to be replaced.
Where instrument calibration is done
Instrument calibration might be done on site or it might have to be given for servicing or repair. In these cases the calibration equipment is sent out for fixing. As calibration is a delicate process, specialized skills as well as equipments are necessary. These might be offered by specialized lab services. In certain cases, sending out an instrument for fixing might be a delicate affair as it needs to be packaged and transported in a way that the parts do not get damaged beyond repair and reach the correctional facility in one piece.
Finding reputed services
If you have a delicate measuring equipment whose calibration needs to be done by technical and experienced personnel, you might have to turn to the manufacturer to get the necessary expertise and help. In most cases, companies provide support to the customers in this matter. In case one has an old instrument which needs to be calibrated, you could opt to seek out specialized services in your area. Many service providers have special tools and lab facilities where the calibration of different measuring devices can be checked and corrected as necessary.
