Perusing our keyword searches, I was surprised to see a great many rather basic searches on MeasurementBlog for what one would consider entry-level measurements.

OK. Perhaps I brought it on by reminiscing about my first serious measurements as part of a lab exercise in college. So, maybe we should put more basic stuff here to help those just getting involved in measurements.

Why not? There are plenty of good resources out there in Web-land and not all are easy to find nor reviewed and organized.

Here goes:

Searched and found a neat little web page on using a vernier caliper and micrometer. It’s a simple set of lab exercises and looks just what a beginner should consider. It is complete with illustrations and a step-by-step approach.

Kudos on a really nice and informative web page written by: Lynn Seery, Asst. Professor QET at Sinclair Community College, Dayton, OH 45402 (email: lseery [at] sinclair.edu.)

To quote his Abstract:

ABSTRACT

This module is a laboratory supplement created for the multi-media challenge grant awarded to the QET Department at Sinclair Community College. Its objectives are;

1) to introduce participants to the theory, equipment, and techniques used in vernier metrology and
2) to provide a context for a more sophisticated use of vernier instruments in further studies and in the workplace.

The module achieves its objectives primarily through a series of three laboratory exercises using a vernier height gage, caliper, and micrometer to measure some gage blocks to establish the accuracy and calibration of the system.

The participant then completes the activity by measuring a machined part with the three different vernier instruments and comparing the results.

Significant tools and techniques of vernier measurement are introduced through the lab exercises and supplemental reading.

Readings are from the text used in the QET Metrology series (QET 111, 112, 113 etc.) Fundamentals of Dimensional Metrology by Ted Busch.
