Summary: In this podcast, we talk about concepts in metrology and measurement. We focus on calibration and measurement uncertainty.
The new Fixed-Length-Optical-Cavity from NIST is the first real revolution is pressure measurement in generations. Today we discuss what it is and how it works
Proper selection of a calibration standard is vital in performing calibration. For this weekend edition of the podcast, I discuss several things you should keep in mind before you attempt to make any measurements.
Metrology is the field of science that underlays measurement. Today we talk about what a metrologist is, and how you can become one.
The Probability of False Acceptance is a key component of ANSI Z540.3. Today I discuss some methods to meet this requirement.
Multimeters can go by a number of different names. VOM, DVM, Fluke Meter, Electrical Meter, but when it comes down to it, we are looking at a family of handy devices. Today I discuss what they are and even give you some basics on how to calibrate them.
Read you calibration quote! Read any quote for services you receive, but read your calibration quote even more closely. There might be things in there that you aren't aware of.
Decision rules are used to quantify how measurement uncertainty is used in comparing a measurement to a tolerance. The way these rules are applied is changing in ISO 17025:2017, so you need to educate yourself to make informed decisions.
For this special weekend edition, I talk about the historical cubit and why it is an excellent demonstration of why traceability is essential.
Today we have a look at uncertainty associated with correction factors and why it is an important factor to consider in measurement uncertainty.
Today we answer a question/comment from a listener as to why manufacturer's specs aren't the only thing you should be looking for in calibration.
In this episode, I talk about an old standard from the brewing world, hydrometers.
Today I give you some tips for choosing a calibration provider to meet your calibration needs.
Today we talk about website updates, my LinkedIn page, and then dive in deep to explain what CMC's on a scope of accreditation are and what they mean.
This weekend we review what I talked about during the week. I give you some updates on the website and other social media, and we discuss 4:1 ratios in depth, their history and how we come up with them.
Today we look a number of different places where measurement is critical, and you probably didn't even think about it.
