TMS Square sensor & calibration tips                                          Your one-stop sound & vibration shop

Welcome to issue #30-
Welcome to our third year of information and education for structural vibration and dynamic calibration professionals.  Our goal is to provide a few "bite size" pieces of information each month to keep you up on the latest in the industry.  Please have a look (like thousands of your industry colleagues do each month!), and share it with a co-worker if you see something from which they could benefit.  Follow the archive links below to where you'll find all the back issues with their wealth of information.
Accelerometer Temp Extremes
Tip of the Month

You certainly wouldn't skip the annual calibration on your instrument, so why skip the annual calibration on your measurement process?  Participating in inter-laboratory comparisons builds confidence and avoids costly problems for you and can prevent embarrassing customer recalls.

The Whys and Hows of Proficiency Testing

ProficiencyThe international standard, ISO/IEC 17025, General Requirements for the Competence of Testing and Calibration Laboratories, references proficiency testing in the context of monitoring activities associated with testing and calibration.  The standard dictates that monitoring activities are conducted in such a manner as to provide data so that trends can be detected and, where practical, statistical techniques applied in the examining of this data.  But what is proficiency testing and what are its relevant properties? The NAPT (National Association for Proficiency Testing) provides a detailed explanation of the whys and hows of proficiency testing...
The Modal Shop is celebrating its 20th Anniversary in 2010.  We hope that you've enjoyed our newsletter again this month, as well as its educational content over the last few years.  No where like the sensing calibration fields are certainty and reliability more important. We're here to serve you with all your dynamic sensor and calibration needs.
