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.” ...

Thinking of tackling electrical repairs but don’t know where to start? With just a little knowledge–and less than $100 worth ...

The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

Before we go forward and run some of the tests that we are going to see hereinafter, let us check a few of the symptoms to understand if those tests are worth doing. We have mentioned some symptoms ...

Back in the early days of electricity, lab workers could measure electric current in a circuit using an ammeter (galvanometer) and voltage using a voltmeter. From there, they could calculate ...

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 ...

We may receive a commission on purchases made from links. A multimeter is a versatile tool used primarily for measuring voltage, resistance, and continuity. Mechanics use multimeters when working on ...
