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 ...

Many data-acquisition systems connect directly to sensors. As with all measurement systems, you must contend with errors and do your best to minimize them. Errors caused by thermal drift, EMI/RFI, ...

The German sensor-maker Leuze claims that it has been able to cut measurement errors in demanding industrial applications by ...

Raised intraocular pressure (IOP) increases the risk of glaucoma. Eye-care professionals measure IOP to screen for ocular hypertension (OHT) (IOP>21 mm Hg) and to monitor glaucoma treatment.

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 ...
