Device Resolution and the Impact on Consumer Risk - Intro If a device's uncertainty has too coarse of a resolution, then you need a device that does not subject the conformance decision to higher risk. This blog will present examples that demonstrate why best practices should be followed for conformity assessments rather than drafting individual […]
TAR versus TUR: Why TAR should RIP ASAP In our last blog, Examining the History of TAR and TUR, we examined several outdated, and to some extent wrong, practices, such as Test Accuracy Ratios (TARs) and requesting NIST traceable calibrations. Remember when they buried the word "DEF"? Maybe we, as metrologists, need to do that […]
Examining the History of TAR and TUR Why examine TAR and TUR? Hasn’t each topic been covered for decades now? When we look at TAR and TUR concepts, we find that many in the metrology community have adopted TUR. Both guidance documents and standards have moved away from TAR. However, when we look at the […]
Torque Calibration: Why Torque Control is Important - Intro At Morehouse we teach torque classes, give webinars on torque, and perform torque calibrations on reference standards. We strive to create a safer world by helping companies improve their force and torque measurements. However, we are not immune to the safety hazards that can result from […]
Calibrate your Tuffaloy Weld Force Gauge A weld force gauge accurately measures the actual weld force at the weld. It is important to calibrate these instruments because a weld force that is too low or too high will cause problems such as cracking, indentation, expulsion, and low weld strength. Most spot welding equipment does not […]
Reduce Beginning and Ending Zeros At Morehouse, we generate calibration reports that follow the ASTM E74 standard. When customers try to replicate the data, they often ask how we reduced the zeros from the raw data. This blog explains Method A and Method B zero reduction per ASTM E74. Morehouse recommends Method B, which reduces […]
New Force Calibration for Technicians eBook Morehouse is excited to announce our new eBook, Force Calibration for Technicians and Quality Managers: Top Conditions, Methods, and Systems that Impact Force Calibration Results, written by Henry Zumbrun. Since force calibration is mechanical in nature, there are many factors to consider. This eBook introduces basic topics of force […]
What is My Load Cell Accuracy? At Morehouse, we are frequently asked about Accuracy, with a question such as “What is the accuracy of this system you offer for sale?” or "What is the load cell accuracy?" At first glance, it should be an easy question to answer, and, indeed, we could simply give a […]
Force Calibration Lead Time Problems and 4 Ways You Can Avoid Them We all deal with scheduling force calibration a little bit differently, and most of us struggle when our equipment is out for calibration. Imagine this scenario. The company we send our equipment to promises a turnaround time to meet our schedule. That date […]
