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 ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around ...

Using a multimeter can be daunting to the uninitiated, but they're not magic. Here's a rundown of the basic functions of the device and what they're used for.

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, ...

For measuring resonance in circuits, a grid dip meter was also helpful. However, most modern users/operators aren’t accustomed to using that anymore. Report comment ...

For a 45-meter RG-58/U cable, the LED will flash at f1 = 1.67 Hz. When an open circuit is introduced at L2 = 25 meters from the IC, the LED will blink at about f2 = 3 Hz.

For the old meter on the left, I have it set to a maximum current of 750 milliamps and the digital is at a max current of 200 mAmp. Now let's add this to the battery-bulb circuit. Here's what that ...

The multimeter should now display a reading of 120 volts or slightly above. You've now confirmed that house electrical power (120 volts AC current) is reaching the switch, coming from the wire on ...
