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.” ...

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 have replaced traditional analog meters long back. It offers better accuracy, reliability, and better handling of impedance. It is a versatile device in the truest sense. You can ...

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...

Digital multimeters are precise and accurate instruments, with some models being very expensive. No matter the cost, one problem pervades every one of these devices: They do a poor job of conveying ...

[Rajendra] tipped us off to this really slick hack he’s done to allow his multimeter to tell the ambient temperature. He’s basically measuring the output of an LM35 temp sensor that he has mounted in ...

In recent years, the electrical industry has seen positive trends toward proper electrical safe work practices and utilization of personal protective equipment (PPE). However, one very routine task ...

Keep your multimeter handy right on your iPhone (or iPad/iPod Touch). The wireless multimeter iDVM by Redfish Instruments can wirelessly link to your iOS device. You can measure voltage, current, and ...
