If you are new to force calibration or metrology, the information can be overwhelming. Force Calibration Guidance for Beginners simplifies everything you need to know. Since force calibration is mechanical in nature, there are many factors to consider. Force Calibration Guidance for Beginners provides a basic understanding of force calibration, the methods and instruments used, industry standards, and best practices.

Force calibration guidance for Technicians and Quality Managers covers more advanced force calibration topics including loading conditions, adapters, verification of the adjustments, indicators, measurement uncertainty, and selecting the right calibration method. This force calibration guidance will help anyone correct force measurement errors, resulting in better force measurements.

There is a common misconception about equipment “being compliant” with ISO 376.  Many struggle with how to use an ISO 376 calibration and put together an uncertainty budget.  ISO 376 Uncertainty Guidance simplifies everything. ISO 376 Uncertainty Guidance provides guidance for the evaluation of measurement uncertainty in the calibration of force-measuring instruments to support CMC in the scope of accreditation and calibration and/or measurement certificates/reports.

Morehouse technicians have seen many different load cell issues and have lots of experience identifying and fixing the problems. With this experience, we developed a 7-Step Process for Load Cell Troubleshooting, which will reduce the hours wasted troubleshooting a nonworking load cell to diagnose the problem. Load Cell Troubleshooting Guidance is a must-read for any technician. Click here to download the load cell troubleshooting guidance document.

Force-measuring instruments are susceptible to errors from improper adapters, misalignment, and not exercising the instrument to full capacity. Force Calibration Adapters Guidance provides guidance for replicating how the force-measuring instrument is used, keeping the line of force-free from eccentric error, and overcoming safety concerns with old adapters.

Uncertainty Budgets for Force document provides guidelines for identifying all significant contributions to measurement uncertainty in the calibration of force-measuring instruments. It serves as a means for laboratories to be compliant with A2LA R205 – Specific Requirements: Calibration Laboratory Accreditation Program.

Calculating Force Uncertainty for force machines. This free document identifies all significant contributions to measurement uncertainty when using a force calibrating machine. Calculating Force Uncertainty describes what is needed to achieve a measurement uncertainty of better than 0.02 % of the applied force.
