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

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.” ...

The purpose of a multimeter is to enable you to test electrical circuits and record resistance, voltage and current measurements for future reference. Recording circuit measurements during alarm ...

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.

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 ...

Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...
