I take your point guys - but a meter that runs out of steam at 1K doesn't inspire me with accuracy, and I'm left wondering that the true RMS and RMS readings are actually pretty close in real terms - what are we looking at here? Electricians are concerned about noise on the AC mains waveform distorting the calculation of the RMS voltage - but in audio waveforms, we don't have anything other than a sine wave, noise free down to very low levels. The sparks drive this true RMS requirement. Is it really important in audio circuit measurements? Back in the days when we were aligning audio kit we did not have true rms to deal with at all.
I've got do disagree with my view of scopes too - I'd happily read the value on a decent digital meter (within it's spec) but I like the confidence of seeing the display on screen showing the waveform - after all, if there is a sizeable noise component, or harmonics, you'd see them and be able to measure them.
I guess I have to agree that even a 30 yr old meter of the Fluke's quality will produce meaningful readings given the right kind of input. I think maybe I've grown out of all purpose meters?
