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 ...

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 ...

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 ...

In the previous article in this series, we looked at bridge circuits used to measure impedance. Now, let's look at some more (simple) math. The scaled bridge voltage and current, v vx and v ix ...

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 ...

Designed for fast throughput of component evaluation in a high volume production environment, a new LCR meter joins the company’s Digibridge family of impedance measuring instruments. The 1730 LCR ...

Keysight Technologies today introduced three low-frequency options for its E4982A LCR meter. With these new options, the E4982A is suited for RF inductor, coil, and EMI filter manufacturers that are ...
