Most precision digital multimeters (DMMs) and many source measurement units (SMUs) offer both two-wire and four-wire resistance measurement capabilities. However, these two techniques are not equally ...

I WISH to direct attention to the performance of Minalpha wire as supplied by Johnson Matthey when used as the filament in an electrical resistance wire strain-gauge, and also to indicate the effect ...

Download this article in PDF format. Proper wiring and probing/contacting are critical to making successful measurements. When testing cells or batteries, using good engineering practices is important ...

Interpreting a data sheet for a static-control product requires a certain level of knowledge and experience. Often, you must wade through myriad specifications, test methods, and claims without fully ...

Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...

Insulation failure is the root cause of many electrical conductors and equipment failures. When insulation fails, not only can equipment be damaged, but fire and shock can also result. Ideally, when ...

The transmission of an electrical analogical signal between two devices requires a suitable cable that should allow for transferring it with low distortion and losses. Ideally a cable does not ...

Researchers at Arizona State University have developed a relatively straightforward method for measuring the electrical resistance of single molecules. The advance, a technical achievement in terms of ...

Metrological institutes on a chip: Efforts like this one seek to bring cutting-edge measurement-science technology and expertise from national metrological institutes directly to users. (Courtesy: ...
