How to Gain Confidence in Your Measurements In the book Good to Great a concept is illustrated with three intersecting circles, which determine your company’s hedgehog concept. The hedgehog concept is based on asking three questions. “ 1. What are you deeply passionate about? 2. What can you be the best in the world at? […]
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 […]
Why Don’t My Load Cell Force Measurements Match My Calibration Report? You send your load cell out for calibration. When it returns, you begin using the load cell but notice that your measurements don’t agree with what the calibration lab reported. Why is there a discrepancy? This question has been posed to us in slightly […]
3 Ways to Prevent Damage to Your Force Calibration Equipment The purchase of force calibration equipment coupled with the calibration cost can be a large investment. Good, quality equipment provides a steady return on your investment for many years. Unfortunately, we see a lot of equipment damage such as broken connectors, severed cables, damaged load […]
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 […]
How to Reduce Leading and Trailing Zeros in Force Calibration in 4 Steps 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 […]
How to Use a Load Cell Alignment Adapter for Compression Calibration Setups Centering a load cell is critical to obtaining the correct line of force and reducing calibration errors. An alignment plug along with an adapter plate can be used to center a load cell, whether it is a reference standard in a calibrating machine […]
Does a Backup Load Cell Meter for Your Load Cell System Make Sense? Backup Load Cell Meter - Reason Why On Might be Needed A client has four load cells on one meter, and the technician loses, drops, or breaks the current indicator. This is a scenario we see happen quite a bit. If Murphy […]
The Top 3 Things to Consider When Purchasing a Load Cell Usefulness may be the one word we often neglect to consider when purchasing force-measuring equipment or any test equipment. Let's think about that for a bit and let it sink in. Most people I have run across seem to be concerned with price, a […]
Important Aircraft and Truck Scale Calibration Tips Figure 1: Example of Aircraft Weighing Aircraft and Truck scales come in all different shapes and sizes and typically serve one purpose, to approximate the weight of an aircraft or truck. Why might that be important? For Aircraft, it's about knowing the center of gravity CG. The center […]
Force Measurement Error – Time Interval Between Two Successive Loadings Has anyone ever wondered if there is a difference in calibration results if the time interval between two successive loadings is changed? Is faster better and does it matter if the calibration takes 10 minutes on an automated machine pictured in Figure 2 below, or […]
What Makes a Force Calibration Machine Fit for Use? - Intro Figure 1: Morehouse 1,000 lbf automated deadweight machine At Morehouse Instrument Company, we’re justifiably very proud of our 1,000 lbf Automated Deadweight Machine. You can see in Figure 1 (above) that the force calibration machine looks level and square. What the picture doesn’t show […]
