When soldered to a 2V-input, 31⁄2 digit DMS-30 Series meter, the DMS-EB-RMS Application Board enables the meter to display the true rms value of AC voltages up to 750V with a resolution of 1V. When ...

How many times have you poked around a circuit with a digital multimeter (DMM), read an AC voltage value, then gone on your merry way? Ever wonder if your meter is giving you peak value, average value ...

The design of a true 100µV rms-to-DC converter can be straight-forward, explain Chau Tran and David Karpaty from Analog Devices. A fundamental measure of an ac signal, root mean square (rms) is ...

The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.

Low-end meters measure an AC signal’s average voltage or current. That’s fine for measuring clean sine waves, but I’ve yet to see such a waveform except when produced by test equipment. With AC ...
