When a warehouse manager suspects poor system performance, the first step is typically to check the real data. Unfortunately, more than 50% of the time, system performance is measured incorrectly.

All analog measurements — voltage, current, temperature, humidity, etc. — include some amount of error. Your job is to minimize those errors enough to give your ...

Test instruments such as oscilloscopes and DMMs (digital multimeters) often let you get the measurement results you need with just the press of a button. But the number on a meter's display or the ...

The venerable Kelvin-sensing circuit, or four-terminal measurement circuit, minimizes measurement errors that your test equipment and test leads can impose. It is named for William Thomson, Lord ...

There are many ways that measurement can be used in the diagnostic process and in assessing the incidence of diagnostic errors, according to the committee that authored the Institute of Medicine’s ...

Measure twice, cut once. That’s sound advice, though no guarantee you won't measure wrong twice. Some measuring errors occur before the ruler is in hand, while interpreting plans. Other errors spring ...

Process Engineer Richard Kasica of NIST’s Center for Nanoscale Science and Technology holds a wafer of the type typically produced in the plasma-enhanced chemical vapor deposition chamber. A new study ...

Calibration cubes have long been a staple for testing and adjusting 3D printers, but according to [Stefan] of CNC Kitchen, they’re not just ineffective—they could be leading us astray. In the video ...

Patch-clamp recording techniques have revolutionized understanding of the function and sub-cellular location of ion channels in excitable cells. The cell-attached patch-clamp configuration represents ...
