The DMM is arguably the most versatile electrical test instrument we have. Even the most basic model can measure voltage, current, and resistance. You can use the resistance measurement function for ...

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 ...

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 ...

The resistance and conductance of a battery are two parameters that can be used to determine the health of battery strings and identify failed cells. As the two different values have a such a close ...

When it comes to digital multimeters (DMMs), you truly are spoiled for choice. There literally are hundreds of models. The problem is to find the best DMM to match your price and performance ...

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

Multimeters. They've been described as the tape measure of the new millennium. But what exactly is a digital multimeter (DMM) and what can you do with it? How do you make measurements safely? What ...

Researchers have developed a method for predicting how changes to manufacturing processes and materials will impact battery life. University of Michigan engineers have identified internal resistance, ...
