Calculator How To's

This short video explains how to use the basic tolerance calculator from the website, located on the uncertainty toolkit page.
In this short video, I demonstrate how to use the PFA calculator from to calculate a guard banded tolerance for measurements to assure a 2% probibility of false acceptance.

Basic Calibration Topics

In this video we break down the basics of what calibration and traceability are all about

This a short video I put together about basic concepts in calibration, including measurement uncertainty. For this presentation I use a common measuring cup to demonstrate measurement concepts.

Measurement Uncertainty

Here's a short video showing you how to calculate a measurement uncertainty using the basic excel file available at

Here's a video where we talk about Quantifying measurement uncertainty contributors 

In this video I show you how to use the Excel Range Uncertainty Calculator to generate a scope line style uncertainty for a pressure gage
