If you don’t know much and you want to learn more, here are some things that you should know about calibration service. The most important characteristics of measuring instruments and measuring equipment are changing over time. These changes are conditioned by environmental influences, mismanagement, and the wear of measuring surfaces. Calibration is a set of operations that aim at establishing, under certain conditions, the relationship between the quantities that are read on the instrument indicator and the corresponding value of the standard. The result of the calibration can be given in the form of a document, that is, calibration certificate. The result can be expressed as a correction in relation to the display of the instrument. Calibration defines changes made to a measuring instrument during use. Ethalon is a measure, benchmark, or measurement system intended for determining, storing and reproducing a unit of measurement for the transfer of its value to other benchmarks to serve as a reference value. Yes, we know that all this may sound quite confusing, especially if you are not from the field, but in the list, we’ll try to make it simpler. Make sure to read our list of things you should know about calibration.

  1. There is something called calibration uncertainty

Of course, nobody says that calibration is one hundred percent certain, as there is always a small possibility of uncertainty when it comes to the accurate instrument’s measurement. This may occur out of many reasons, including the lab or environment conditions. Uncertainty is acceptable and expected, but should definitely be worked on.

  1. …and calibration traceability

NIST defines traceability as the “property of a measurement result whereby the result can be related to a reference through a documented unbroken chain of calibrations, each contributing to the measurement uncertainty”. Traceability is done for the purpose of showing that the instrument calibrations have been accurate.

  1. Calibration importance

If you don’t calibrate your instruments, you can never be sure that they are actually accurate and reliable.  Over time, certain instruments tend to lose their stability, so calibration is actually in a way maintenance and the best possible thing to do to preserve your instruments.

  1. How often should you calibrate an instrument?

This really depends on the type of an instrument and how often you use it. Some instruments need to be calibrated daily, while some may go for over a year without needing to be calibrated. When it comes to your specific instrument, you should definitely consult the calibration service or the instrument seller.

  1. What should be calibrated?

Believe it or not, the instruments and gadgets you use every day and you maybe did not know they need to be calibrated are things such as your smartphone home button, your Macbook battery, PC monitor, laptop charger, and many other things that are used on daily basis. Calibration in these cases is quite important, in order to ensure that your essential gadgets will be preserved for a long time, without having to invest a lot in the new ones.
