The Process Of Calibration And Calibration Services
RS Calibration
The concepts of accuracy of standard or measuring instrument find their places under the term calibration. It takes care of measurement error and uncertainty.
Calibration is a process where you can compare measuring instrument with a measurement standard to facilitate the relation between the values indicated by the instrument and those of the standard.
Calibration involves comparing of a measurement device that is unknown, against the better standard. Calibration is often considered as something that includes the process of adjusting the output/indication on a measurement instrument to meet the value of the applied standard within accuracy. Let's take an example of thermometer that indicates errors. This indication of errors in thermometer can be corrected and adjusted using calibration constants. As a result, it will show the true temperature in Celsius at specific points on the scale. In computing, by way of proper calibration of an interactive white board pen or other input method the relation between the physical pen position and the position of the cursor on the screen is established.
Demonstrable traceability has to be there to give confidence in the accuracy of calibration results.So it is necessary that the results we achieve through calibrating measurement standard used has be traceable back to standards through an unbroken chain of comparisons where each link has declared a kind of measurement uncertainties. These standards have to be held at a national measurement institute. In the calibration process trained and authorized personnel has to use appropriate equipment and procedures. Great importance was laid on traceability. This traceability notion is seen in different organizations, documents, techniques and measurements within a large and diverse measurement community. That is why one has to be systematic with a view to interact with each other or with our clients.
Modern metrological notions normally link the topics of measurement traceability, quality assurance programs etc, to the topics of measurement uncertainty. One of essential components of all uncertainty budgets is the employment of calibrated standards or instruments. The calibration process transfers a reference value, usually an International System (IS) unit, to the instrument/artifact under calibration establishing the unbroken chain of comparisons required for traceability.
As calibration is the only process that determines the measurement capabilities of the instruments, systems or instruments usually have to be calibrated to achieve accuracy in measurement.
