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.

One of the most common measurement errors is using the wrong tool for the job. For example, using a tape measure to estimate small mechanical tolerances or relying on a bathroom scale to track precise ...

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 ...

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 ...

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

Measurement error models address the deviation between observed and true values, thereby refining the reliability of statistical inference. These frameworks are ...

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 ...
