OK, so meter is Fluke 29, is that a sine wave meter? Use it for general multimeter functions so never gave it much thought.
It may depend on which series it is, but at least the series II version is not a true RMS meter, but average responding. From the manual: "AC conversions are AC-coupled, average responding, and calibrated to the RMS value of a sine wave input."
Note that any style of multimeter will give accurate results with a sine wave; it's when the waveform deviates from a sinusoid that the readings become incorrect (or at least are not RMS readings) for your multimeter--and, for that matter, for my Fluke 73 series II, which is generally similar but a lower-end model and gray rather than yellow. They are excellent meters.
