Force Measurement Error – Time Interval Between Two Successive Loadings

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 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 two […]

What Makes a Force Calibration Machine Fit for Use?

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 is the rigidity of the machine, how plumb the weights are, […]

Using Mass Weights to Calibrate Force Devices Can Result in a Large Measurement Error

Morehouse Benchtop 10,000 lbf Calibrating Machine When metrologists talk about measurement error, we’re talking about the difference between the nominal value and what the instrument is reading. If 10,000 lbf is applied to a force measuring device and the readout displays 10,002 lbf, then the device has a 2 lbf bias. If we load the […]

Proving Ring Tare Load Correction Proof

Proving Ring Tare Load Correction Proof This blog post is on the strange side. I was rummaging through some of the work I did back in 1999 and found a proving ring tare load correction proof. I probably never published it as we were all waiting for the world to end at the turn of […]

Calibration Intervals - When is it time to recalibrate?

Calibration Intervals - When is it time to recalibrate? Since I became involved in the calibration industry in 1972, calibration intervals have been a common topic of interest and confusion.  I was asked to write an article for the newsletter & blog, and after some thought, I determined there was no need.  Many people have published excellent […]

Battery life may impact your calibration results

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 […]

Our goal is to help anyone making force […]

Load Cell Measurement Errors - Top Block Adapter Hardness and Flatness

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 - Setup Reduction With Morehouse Quick Change Tension Members and Adapters

Tips from the Cal Lab – 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 (Setup Reduction) to set up equipment for a load cell calibration. During the class, the concept “quick […]
