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 ...
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 ...
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 ...
