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

Researchers at the Kastler Brossel Laboratory in Paris have made the most precise measurement of one of the fundamental constants, called the fine-structure constant, providing physicists with a vital ...

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 ...

In order to measure the mechanical properties of materials in compression, tension, bending or torsion, a universal testing machine is utilized. This article outlines the two different types ...

Temperature is by far the most commonly measured physical parameter. With so many new ideas for connected devices in the works for consumer and industrial applications, you often need high-accuracy ...
