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?
