Applied Fundamentals of Force Calibration

This course will cover applied force calibration techniques and will include live demonstrations using secondary standards to exhibit potential errors made in everyday force measurements. The measurement errors demonstrated and discussed will include errors associated with improper alignment, use of different and/or incorrect adapter types, thread depth and thread loading.  The course will cover the basics of measurement uncertainty and provide the tools for anyone to put together a CMC or uncertainty budget.
We will cover the basics required for you to understand the requirements and get you running by providing practical examples and worksheets that you can apply to estimate measurement uncertainty required for ISO/IEC 17025 and ANSI Z540.3 requirements. The ISO Guide 98-3 (GUM) process is broken down in a simple process and applied for you to implement in your laboratory whether it is for calculating the measurement uncertainty for reporting your CMC (Calibration and Measurement Capability) for your scope of accreditation or for reporting it on your calibration report for the customer (ILAC P14 requirement).

  • Common Types of Force Measuring Instrumentation
  • Troubleshooting a Load Cell
  • Calibration Traceability
  • ASTM E74 and Other Force Calibration Procedures
  • Troubleshooting a Load Cell
  • Requirements for ISO/IEC 7025 and ANSI Z540.3.
  • Basic definitions relating to Measurement Uncertainty.
  • Basic Statistics required for Measurement Uncertainty.
  • The GUM process simplified
  • The Measurement Uncertainty Budget implemented in a spreadsheet (Template provided).
  • Reporting Measurement Uncertainty (Scope of Accreditation CMC, Customer Reports)
Anyone who is currently performing force measurements.


After successful completion of the course, the trainee will be able to:
  • Know how to prevent common measurement mistakes
  • Be able to perform diagnostic checks on a load cell
  • Understand concepts and standards presented
  • Put together an uncertainty budget using the materials provided
