Measuring AC current (220-V mains RMS current) is not as simple as measuring DC current. In DC current measurement, you can simply hook the oscilloscope probe to the shunt resistor and calculate the ...

Extech Instruments announces its MA640 600A True RMS AC/DC Clamp Meters + NCV that has a higher accuracy rating then standard RMS meters. To use a clamp meter, only one conductor is normally passed ...

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 few months ago a personal computer trade magazine reviewed surge voltage protective power strips for home use. The article offered an explanation of what “120 volts RMS” power (what we typically ...

If you measure a DC voltage, and want to get some idea of how “big” it is over time, it’s pretty easy: just take a number of measurements and take the average. If you’re interested in the average ...
