hm, without checking your MM of choice all that thouroughly, I'd say it is quite comparable to the one I have.
I'm a bloody beginner when it comes to this to be quite honest, so I talked to some electrical engineers with an Eurorackbackground who explained to me that a) the tools to be REALLY precise are well worth 5 - 10 times more expensive than these we're looking at and (b calibration within the standards of musicality are well enough possible wirh MMs like the one shown.
So my advice is not worth that much, but still, I'd say you can get away with that Multimeter, at least so did I and still enjoy to explore the Multimeter itself. I'm happy when I can errortest connections to fix a broken solderjoint on an old crappy mixer at least and countercheck the voltages supplied by Data for makeshiftcalibration.
