I have a Fluke 87V, which is a True-RMS DMM, and I would like to measure the current in my circuit. I have 2 motors being driven by a PWM so I wonder if the DC current or the AC current measurement of the DMM will be do the job for the PWM current. Is it there a recommended way to measure this kind of "mixed signal" using a regular DMM as a Fluke 87V?
Is it there a recommended way to measure this kind of "mixed signal"?
Use a DMM with a AC+DC TRMS measurement capability?
What of sort frequencies, voltage levels?
(I'm not an AC power guy so if you blow something up...)
But I could imagine a shunt, and then a low pass and high pass filter. Just RC's if you can throw power away.. and move heat away. You'd have to work out the response functions.
