For all of you who have a multimeter thrown in a drawer or toolbox but don’t know how to use it, these instructions will help in your search for missing voltage.

Between testing old components, measuring voltages and checking the continuity of circuits, you'll be reaching for it all the time. But there are many other applications in a 'meter, so it's ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop?

For automotive circuits, we recommend an auto-ranging meter with at least 20MΩ of internal resistance. Make sure to use the correct multimeter setting for a car battery.

With an included test lead set, the Fluke 117 multimeter costs nearly $300, which isn't cheap, but this tool is loaded with features and should last for many years, even under difficult conditions.

A multimeter is an electronic measuring instrument that is used to gauge volts, amps, and resistance from an electrical source. The most common automotive application for a multimeter is to test the ...

The meter beeps when it detects a closed circuit, so there’s no need to look at the meter while testing. The resistance required to trigger the beeper varies from model to model of DMM.

The Harbor Freight MADDOX back-probe kit lets DIYers test automotive sensors safely. Just insert between wire and insulation, ...

Multimeters are indispensable tools when working on electronics. It’s almost impossible to build any but the most basic of circuits without one to test and troubleshoot potential issues, and … ...

Testing branch circuits Branch circuit wiring problems lead to more residential electrical fires than any other single cause. Hidden trouble inside a branch circuit can also lead to electrocutions and ...
