Meters. You can compute RMS voltage using an oscilloscope. However, with a meter, it can be tricky depending on what the meter measures. Most meters that don’t claim to measure RMS, ...

Sure enough, a true rms meter reads the signal as 353.53 mV. Its less expensive average-responding cousin reads the signal as 351 mV. Unlike the pure sine wave, ...

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 ...

Using a non-RMS meter on these loads can cause a lower-than-true value — up to 40-percent lower in some cases. Therefore, the next time you need to purchase a multimeter, spend some time looking at ...

When you want an Average reading meter you select a 77, When you want a True RMS meter you choose a 177. The last thing people want with a 77 is for it to only be available in a True RMS type.

Extech Instruments has introduced the MA620 (AC) and MA640 (AC/DC) 600 A true RMS clamp meters. Extech Instruments has introduced the MA620 (AC) and MA640 (AC/DC) 600 A true RMS clamp meters. The ...

Technicians have been using average responding meters, an industry standard, for years, and for years they’ve been appropriate. However, the digital waveform on most of today’s electrical loads ...

I really liked that it measures ac signals with true RMS. The Fluke 187 also has a capacitance meter, and could measure current from microamperes to amperes. I also believe in redundancy, so after a ...

Just use a Wattangel or clamp meter and read the power cord, that's how many watts you are using. You can also use a True RMS meter and a sine wave tone generator to measure the power output, but ...
