How to avoid the most common mistakes in field calibration - Beamex webinar

This post includes the recordings of the two-part webinar series titled “How to avoid the most common mistakes in field calibration” we recently did together with our partner ISA (International Society of Automation).

ISA develops standards, certifies industry professionals, provides education and training, publishes books and technical articles, and hosts conferences and exhibitions for automation professionals. More information on ISA can be found at https://www.isa.org/

The webinar speakers have a lot of experience in automation and calibration:

  • Hunter Vegas has over 30 years of experience in various automation projects. He currently works for the company Wunderlich-Malec.
  • Ned Espy has worked over 20 years with calibration management at Beamex, Inc. and also has calibration experience from his previous jobs.
  • Roy Tomalino has worked 15 years at Beamex, Inc. teaching calibration management and also has prior  calibration experience.

To make it easier for you to find out what was discussed in the webinars, I have done a short table of contents with the starting times of each topic. This makes it easier for you to see if there are some interesting sections and to quickly jump straight into that section. Please note that this table of contents does not list all the things discussed, so I recommend checking the videos fully through. The videos include a lot of practical issues and considerations.
