On infrequent occasions, I am asked to design a circuit to measure the RMS value of a current or voltage for some kind of power measurement. Since the work I do is hardly unique, I thought some of you ...

Jim Williams was always intrigued by RMS measurement. Implicit computing RMS-to-DC converters like the old Analog Devices modules, and later the monolithic devices, were interesting to him from a ...

Murata Power Solutions has introduced the DATEL DMS-20RM series of voltmeters that can measure the true-rms value of complex ac voltages and, with an input frequency range of 47 - 1kHz. It is ideal ...

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, ...
