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 ...

The DMM is arguably the most versatile electrical test instrument we have. Even the most basic model can measure voltage, current, and resistance. You can use the resistance measurement function for ...

While it's often best to call an electrician if you suspect you have a dangerous electrical issue, you can also safely diagnose many of those problems yourself with a multimeter, which is why it's ...

Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...

When a voltage is applied to a material or device,current will flow through it. How much current will flow is based on theresistance that the material applies to a circuit. The resistance of a ...

If you were to ask a random Hackaday reader what their most fundamental piece of electronic test equipment was, it’s likely that they would respond with “multimeter”. If you asked them to produce it, ...
