Tip of the Month

Run and record the results from a known, controlled verification sensor each time you use your calibration system. Plotting the result in a control chart will allow you to watch for drifting bias anomalies like inexperienced operators (incorrect/inconsistent mounting torque), environmental control bounds or reference drift, as well as high deviation special causes, like ground loops or other drastic measurement errors.

10 Best Laboratory Practices

Top10The following article does a very nice job of highlighting the skills, competencies and controls needed to achieve continued excellence in test and calibration.  Don't be dissuaded as the article starts with the framework of a chemistry lab. The 10 best practices are universal in their application across any proficiency testing such as round robin tests with other capable and reputable laboratories.  While apprentice training and starting capability are important, only proficiency testing ensure that practitioners maintain their instruments, skills and procedures to demonstrate capability over time.

Blast from the Past...

For those who may be new to our newsletter, we wanted to highlight an article from a previous sensor & calibration tips - Common calibration system options...

Air Bearing ShakerFrequency response function (FRF) and single point reference frequency amplitude sensitivity are the most common forms of accelerometer calibration.  However, laboratories are becoming more interested in supplemental test capabilities to ensure both the health and performance of their users' accelerometers...
