A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

Although a power supply and a DMM are fine for some measurements, there are many advantages to having sourcing and measuring in the same instrument. Yet many engineers I encounter are not familiar ...

Measuring a voltage is pretty easy: just place your multimeter’s probes across the relevant pins and read the value. Probing currents is a bit trickier, since you need to open up the circuit and place ...

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 ...

Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...

Measuring live voltages and current in today’s high-energy environments can result in a severe hazard to equipment and users if proper precautions are not applied. Given the risk of transients, surges ...

I'm having problem with a starter motor on a riding mower, and need to check if the motor is getting juice and not working or if something else isn't working and no juice is getting to the starter.

Measuring dynamic current flow has always been an important parameter for managing system performance, and doing so has become even more so with the proliferation of smarter management functions for ...
