While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

While only 12 of the 203 reviews award the MM420 fewer than 4 stars, there are some issues worth noting. The most common ...

Part of Design and Technology Electronic and microelectronic control systems Using Ohm’s Law (V=ꞮR), you can calculate the expected values for voltage, current, and resistance in a circuit. Ohm's law.

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, ...

You can characterize a semiconductor device to be its own temperature sensor by using an accurate four-wire measurement technique. Semiconductor junctions — from the millions of transistors used in ...

A multimeter is a versatile tool that can be used to measure voltage, current, and resistance in electrical circuits. It combines several measurement functions into one device, making it essential for ...

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 ...

You can use a multimeter with capacitance-measurement capability to measure the length of wire or cable to an open circuit. The capacitance of a pair of wires (or a wire to a shield) is directly ...
