What is the Best Load Cell for a Reference Standard? What is the best load cell I can use as a reference standard? This question appears straightforward, but once we start to examine the issue, it takes a series of questions to answer. The most common answer is, "Well… that depends on what your expectations […]
Morehouse Universal Calibrating Machine The Universal Calibrating Machine (UCM) is designed with flexibility in mind, offering a clear path to automation without the high upfront cost. While UCMs are often priced up to 50% less than fully automated systems from other manufacturers, they can easily be upgraded to a fully automated solution at any time. […]
Have trouble understanding Uncertainty Propagation for Force measurement and how to put together a budget? This paper examines all of the components required to put together a full calibration and measurement capability (CMC) reviewed by Accreditation Bodies for your scope. This Uncertainty Propagation guide to calculating force measurement uncertainties & was published in Cal Lab […]
How to Participate in an Interlaboratory Comparison (ILC) Many force calibration laboratories need help proving out their measurement capability. The ISO/IEC 17025:2005 listed interlaboratory comparisons (ILCs) in section 5.9.1. However, historically ILCs were not organized or completed because other less complicated methods were acceptable for monitoring the validity of the results. The current ISO/IEC 17025:2017 […]
Deadweight Calibrating Machine Capability Morehouse deadweight machines can calibrate ISO 376 Class 00, ASTM E74 Class AA, AS 2193 Class AA, and other force-measuring devices requiring the utmost accuracy. These include load cells, proving rings, crane scales, force gages, dynamometers, and other force-measuring devices. Morehouse has redesigned our deadweight calibrating machine to be more rigid, […]
Load cell dual-range calibration errors happen when a load cell is not loaded to full capacity. The molecules inside the load cell do not react potentially causing an increased error. What you need to know about molecule excitement decline and dual-range calibrations. Article from Test Magazine May 2016 issue. If you enjoyed this content, check […]
How Do I Calculate TUR? How to Calculate TUR. Correctly calculating Test Uncertainty Ratio (TUR) is crucial because it is a commonly accepted practice when making a statement of conformity. It helps you analyze measurement risk and is often used in decision rules. Although TUR is defined in the ANSI/NCSL Z540.3 Handbook and ILAC G8, […]
Morehouse Portable Force Calibrating Machine The Morehouse Portable Force Calibrating Machine (PCM), designed with field calibration requirements in mind, provides all the necessary force calibration tools in a portable package. This calibrator gives accurate and stable force measurements in a robust and low-maintenance design. The system is equipped with several time-saving features that enable a […]
Why a 4 to 1 TUR is Not Enough: The Importance of Analyzing the Probability of False Accept Risk: Several organizations and publications reference or insist on maintaining a 4 to 1 TUR (Test Uncertainty Ratio) without understanding the level of risk that they may be subjecting themselves to. The general thought is that if […]
