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 ...
The MCTR Series current transducer output is derived from the RMS value of the input for accurately sensing current in single and three-phase applications. The MCTR is ideal in non-sinusoidal current ...
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 ...
