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 ...
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 ...
If you mostly deal with DC current, you might not think much of root mean square or RMS measurements. Sure, you’ve seen meters that have “true RMS” settings, but what does it mean? If you don’t know — ...

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 ...
