Common traits of digital multimeters (DMMs). Classifying DMMs by their amount of digits. What role do digitizers play in making voltage measurements? Measuring voltage may be the most basic ...

Last week, I stepped through the basics of automotive electrical circuits, explained how electrical current needs to flow ...

A common data logging application is measuring voltage or current flowing into or out of a piece of equipment, such as a user monitoring current in solar cells, inverters, or storage batteries. These ...

When working on electrical projects around the home—whether that’s troubleshooting an issue with your HVAC system, repairing an appliance, or testing a car battery—a multimeter is essential. These ...

Imagine a satellite, floating in space. How would you measure its voltage? Yes, it probably has a non-zero voltage, a consequence of geospatial electric fields and ion and electron currents. The ...

The GS820 features the industry's fastest testing speeds, with a typical measurement time of 1 ms, and is capable of highly accurate ((0.02%) voltage and current generation. It also features the same ...

With the right equipment and training, it’s possible to safely work on energized power lines in the 500 kV range with bare hands. Most of us, though, don’t have the right equipment or training, and ...

A farmer is watering an alfalfa field 24 hours a day using a 3-phase 100-hp electric motor and adjustable speed drive (ASD). The farmer checks on his field to find the water not flowing and the pump ...

Probe orientation and shielding can separate real buck-regulator output-voltage ripple from radiated switching noise.

Makers, developers, and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published on the official Arduino blog. This project ...
