When performing complex calibrations, you will likely have several measurement standards involved in your calibration process plus a unit under test. This way you are not overestimating your uncertainty in measurement by considering the resolution of two UUT’s. Instead, you should include the UUT resolution later when calculating calibration uncertainty in accordance with ILAC P14. On the other hand, if you are performing measurements and calibrations where the unit under test can routinely change, you should omit the UUT resolution from your CMC Uncertainty estimates. If you performing measurements or calibrations where the type of unit under test is always the same, you should include the resolution of the unit under test in your uncertainty budget to your CMC uncertainty calculations. In this scenario, you need to consider the resolution of both the measurement standard and the unit under test. Simple Calibrationsįor simple measurements or calibrations, you may only have two measurement devices the measurement standard and the unit under test. However, you have to consider all of the measurement equipment in your measurement system. Resolution uncertainty is a factor that should be considered in your uncertainty analysis. Resolution Uncertainty and Uncertainty Analysis In both examples, industrial measurement equipment were calibrated using precision equipment and the measurement result and measurement uncertainty were significantly influenced by the poor resolution of the unit under test.įor this reason, resolution uncertainty is considered important, regardless of whether or not it’s influence is significant to the calculated uncertainty in measurement. In another example, you can compare the length of a gage block to a digital calibrator, but the resolution of the digital caliper will affect the measurement result and associated uncertainty even if you are using a grade 0 gage block.

Fluke 5700A) to a 3.5 digit Multimeter, the resolution of unit under test will have a considerable influence on the measurement result and associated uncertainty. The device with the worst resolution will limit your measurement capability.įor example, you can compare the voltage output of a multifunction calibrator (e.g. It is important to consider all equipment in the measurement system. No matter how careful or scientific, you measurement results are limited by the resolution of your measurement standards and the unit under test. The accuracy, precision, and capability of your measurements are limited by the resolution of the measurement standard and unit under test. Resolution uncertainty is important because it considers the limitations of measurement equipment. Resolution uncertainty is the uncertainty in measurement contributed by resolution of measurement equipment.

How To Calculate Resolution Uncertainty By Device Type.Resolution Uncertainty And Uncertainty Analysis.Why Is Resolution Uncertainty Important.To help you quickly find answers to your questions, use the link below to skip ahead. In this guide, I am going to teach everything that you need to know about resolution uncertainty and more it is more complex than you ever imagined. So, I have created this guide to help you appropriately identify and evaluate the resolution uncertainty of various measurement equipment. However, evaluating resolution uncertainty can vary depending on several factors.

It’s influence should be considered in every uncertainty budget. Resolution Uncertainty is a factor that contributes to uncertainty in measurement.
