Calibration Report Terms

 

We often have customers ask “What does this mean on the calibration report?"

Let's look at some key features of our calibration reports to give you a better understanding of the terms used.
 

Calibration

Calibration is the controlled and documented process of measuring traceable calibration standards and verifying that the results are within the stated accuracy of the gage. Calibrations are typically performed by a qualified laboratory in a controlled environment using a documented process.
 

Traceability

Traceability is the ability to follow the results of a measurement through an unbroken chain of comparisons, all the way back to a fixed international or national standard which is commonly accepted as the true value. This chain typically consists of several appropriate measurement standards, the value of each having greater accuracy and less uncertainty than its following standards.
 

Reference Equipment

Reference Equipment or otherwise known as ‘Master’: Is an instrument used in the test for comparing results with the unit under test. The Reference Equipment must have a much higher accuracy, compared to the instrument under test. Therefore, the Reference Equipment used must be such that the combined uncertainties of the resultant measurement are less than the stated accuracy of the Unit under Test.
 

95% Confident Level

This means 95% of your readings are going to be within the uncertainty stated in the calibration reports. Example: if your calibrated micrometer results equalled to 50microns with a uncertainty of ±1 microns – this means 95% of your readings are going to be within 49 – 51 microns.
