Calibration Intervals - When is it Time to Recalibrate? Calibration Intervals A calibration interval is the period between two consecutive calibrations of MT&E. This interval is crucial for ensuring that the equipment continues to operate within its specified performance and the claimed Calibration and Measurement Capability (CMC) uncertainty parameter, sometimes referred to as […]
Top 5 Common Force Measurement Errors Top 5 Common Force Measurement Errors - At Morehouse, we strive to replicate the loading conditions a customer may be using. Some other labs, may not follow this process and the additional measurement uncertainty from not replicating use, may create a significant error source. Below are the top 5 […]
Avoid ASTM E74 Load Cell Calibration Mistakes We are writing this post to clarify some common ASTM E74 misconceptions and discuss ASTM E74 Load Cell Calibration Mistakes. We have written two early blogs on the ASTM E74 standard: ASTM E74 Simplified and Calculating CMC using the ASTM E74 standard. We also have a slide share presentation detailing the […]
AC Versus DC (mV/V) Differences in Load Cell Meters Using a Load Cell Simulator Differences in Load Cell Meters - There is a difference in output between Alternating Current (AC) measurements and Direct Current (DC). To show the difference, we used a load cell simulator on two different meters. We used a simulator that […]
Battery Life May Impact Your Calibration Results Battery life may impact your calibration as it is becoming more and more common to have portable devices that use batteries. This can be a great benefit to someone who wants ultimate portability. However, this portability can come with additional errors, if the portable device is not […]
Force Safety Guide when Using Force Measuring Equipment in Various Applications Our force safety guide will help avoid situations that may cause personal injury or equipment damage when using Load Cells, Proving Rings, Force Gauges, and other instruments to which forces are applied; this post was created. Our goal is to help anyone making force […]
Load Cell Measurement Errors: Can a Load Cell Adapter Plate or Block be Interchanged Without Introducing Additional Errors? Load cell measurement errors - Hardness of the top block used for calibration can result in errors as high as 0.5 % of applied force. We have seen large errors from customers switching out top blocks or […]
Tips from the Cal Lab – Force Setup Reduction with Morehouse Quick Change Adapters Morehouse employees went through a lean manufacturing course. Part of this course emphasized reducing cycle time, by reducing the amount of time it would take (Force Setup Reduction) to set up equipment for a load cell calibration. During the class, the […]
Beware of Load Cell Measurement Error - If a Load Cell is to be Used to Make Descending Measurements, it Must be Calibrated with a Descending Range Note: In the above graph the Blue Line represents the descending curve showing high load cell measurement error when compared to the ascending curve. The difference in output […]
Load Cell Transitioning from One Mode to Another. Does it Make a Difference? This post will examine the effects of Load Cell Transitioning by calibrating the load cell in compression by switching to tension and then back to compression versus calibrating in tension first and then compression. We will determine if there is a statistical […]
Force Applications for Mass Reference Standards Our good friend, Mark Ruefenacht of Heusser Neweigh, and a Mass Metrology Instructor at NIST pointed out that most mass calibration laboratories will issue certificates of calibration only listing conventional mass (unless True Mass is requested). Force Applications for Mass may create some confusion for those trying to convert […]
What You Need to Know about Having a Load Cell Calibrated with 2 Ranges Load cell calibrated with 2 ranges has a common error that can be referred to as Molecule Excitement Decline might explain why the use of a low range calibration on a reference standard can lead to additional errors. This post will […]
