TAR versus TUR: Why TAR should RIP ASAP In our last blog, Examining the History of TAR and TUR, we examined several outdated, and to some extent wrong, practices, such as Test Accuracy Ratios (TARs) and requesting NIST traceable calibrations.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 […]
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 […]
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 […]
Load cells calibration basics and why is it important? What are the best methods and instruments to use? What industry standards or best practices should I follow? If you are new to force calibration or metrology, the information can be overwhelming. Since force calibration is mechanical in nature, there are many factors to consider. Load […]
Force Measurement Terms In the previous Back-to-Basics blog, I covered Load Cell Indicator Basics. This last blog for beginners contains a glossary of common terms in force measurement. This is a basic list of terms, and some have not been covered. It is important to post these for reference because most of these force measurement […]
In the last Back-to-Basics blog, I covered Types of Load Cells. As I continue to cover basic concepts for beginners, this blog details how to troubleshoot a load cell. 7-Step Process for Load Cell Troubleshooting Have you ever wasted hours troubleshooting a non-working load cell to diagnose the problem? Morehouse technicians have seen many different […]
5 Common Types of Load Cells In the last Back-to-Basics blog, I covered Load Cell Terminology. As I continue to cover basic concepts for beginners, this blog details the common load cell types used in force measurement and how to choose the right load cell type for your application. The four types of load cells […]
Load Cell Terminology In the last Back-to-Basics blog, I covered Measurement Uncertainty. As I continue to cover basic concepts for beginners, this blog details some common load cell terms typically found on a load cell specification sheet. In this post, I will cover Non-Linearity, Non-Repeatability, Hysteresis, and Static Error Band. There are several more terms […]
In the last Back-to-Basics blog, I covered Calibration versus Verification. As I continue to cover basic concepts for beginners, this blog will define measurement uncertainty and examine why it is important. What is Measurement Uncertainty? What measurement uncertainty is not is an error. It is imperative to understand the difference between these two terms as […]
