Begin Q&A Forum for "MEASUREMENTS AND UNCERTAINTIES AND ERROR PROPAGATION"

2)How to call the time server for National Institute of Standards and Technology?
Thanks.

Relative Uncertainty compares the measurement uncertainty (with units) to the actual measurement (with units.) Therefore, relative uncertainty is dimensionless.
Think through this statement: How does the uncertainty in measurement relate to the measurement? Take the ratio of the two. Please see the lab manual entry for Measurements on page 17.

Please see page two of the lab manual entry for Measurements to find about the NIST phone number for the time server.

Dr. Howey,
I didn't receive the handout the first day and the link for the pdf above is not working for my pc. That said, I do not know what number to call for NIST. Would you please provide?
Thanks!
