Force vs. Mass in Portable Weighing: Why Local Gravity Matters A load does not gain or lose mass simply because it is moved from one location to another. But the gravitational force acting on that load can change. For fixed weighing systems, this usually causes little concern because the instrument is adjusted, calibrated, or verified […]

Why Rounding Matters in Calibration A calibration result is more than a measured number. It is a statement about a measurement together with information describing how well that measurement is known. Consider a force calibration calculation that produces: Measurement result: 10,000.03748 lbfExpanded uncertainty: 2.37483 lbf Reporting all of those digits on a calibration certificate may […]

Load Cell Calibration Best Practices This guide explains load cell calibration best practices for achieving accurate, traceable results, including ASTM E74 requirements, proper procedures, documentation, and recalibration intervals. What Is Load Cell Calibration? Load cell calibration is the process of applying accurately known forces to a load cell and comparing those forces with the electrical […]
