Breaking Down the Calibration Report

After delivering our calibration reports, we often get asked about certain terms on the reports. In this article, we are going to dive deeper into the calibration reports and the terms that are used throughout the reports.

This is the recorded process of assessing and measuring calibration standards and checking the results we receive. These reports are generally documented by a qualified laboratory. The reports should be done in a controlled environment.

This is also known as Master, which is a tool used in the unit under test. The Reference Equipment should be extremely accurate, more so than the instrument under test. The combined questions of the resultant measurement must be a smaller amount than the expressed accuracy of the Unit under Test.

This contains multiple measurement standards, which are highly accurate and have low unreliability compared to the below standards. Traceability lets you follow the outcome of a measurement through a chain of comparisons. It can take you back to a fixed standard.

95% of the readings in the calibration reports are uncertainty stated. This means, if the results of your calibrated micrometer were equal to  60microns with an uncertainty of ±1 microns, 95% of your readings will be between 59 – 61 microns.
