Measuring PWM current?

It's gonna be interesting to see the pissing contest that happens over this one. Hows about you state exactly what you're trying to do, how accurate you need, how much current we talking about?
Read the specs on the meter you are considering.

gives some relevant information for 50-60 Hz. use as long as 100mA resolution and 2% +/- 5 counts accuracy is what you need.

A shunt is the best way. Then a scope probe will reveal all.
The RMS clamp will yield RMS averaged current usage if the pulses are fast enough for it to resolve the average.
