In order to measure the RMS value of an alternating voltage an accurate converter is required to produce the true RMS value of its alternating input as a DC output. With simple sinewave inputs the RMS ...

Hands up all who remember I did a blog on measuring the RMS (root mean square) value of a signal. Hmmm. Nobody! Well for those of you who don’t believe that I wrote one you can find it here: RMS ...

Understanding the meaning of total effective current or voltage can be tricky. This month Mike Lowenstein, president of Harmonics Limited, helps us set the record straight on these oft misunderstood ...

Murata announced the DMR20-1-ACV "nanometer" self-powered four-digit bright LED voltmeter. The DMR20-1-ACV "nanometer" self-powered four-digit bright LED voltmeter from Murata can measure the true RMS ...

Test meters used to just provide the basics: voltage, current, and resistance. Thanks to solid-state circuitry, though, today's instruments are packed with several features the typical electrician may ...
