The sessions will include formal lecture, class discussion, group exercises, audio-visual presentations, and some hands-on practice. The focus of this class will be on a variety of mechanical and electronic weighing instruments and include specific topics related to these types of scales such as: device suitability; application of tolerances; specialized tests procedures; and installation, maintenance, and use requirements. 

Learning Objectives:

After this seminar, participants will be able to:

  • Correctly APPLY requirements and procedures outlined in NIST EPO 12
  • UNDERSTAND and CONDUCT official examinations (inspection and tests) using all appropriate NIST Handbook 44 requirements and requirements from the USDA, Packers & Stockyards Program on livestock and animal scales
  • INTERPRET scale test results

Materials & Supplies:

A course manual and class materials will be provided.


Qualified participants must have a fundamental understanding of weights and measures practices, procedures, and the use of NIST Handbook 44 – Specifications, Tolerances, and Other Requirements for Weighing and Measuring Devices. As a prerequisite to this class, participants are required to complete the NIST Office of Weights and Measures (OWM) “Handbook 44 Self-Study Course.”

Minimum Requirement(s):

To obtain a course certificate for this class, students must be in attendance for the entire class; participate in all group activities that are planned; and achieve a score of 70 percent or higher on a final exam, which will be administered on the last day of the class. Students who do not fulfill these requirements will not receive a certificate of completion.


State weights and measures field officials, local enforcement officials, and service agents.


There is no fee to participate. However, all travel, lodging and meal expenses will be the responsibility of the attendees. There will be adequate parking available at the VDACS location.
