Nice, I'd like a bench DMM, but, I can't see any real benefit over my Fluke 179.
My Fluke also appears to be better spec.
What do these Rigol units do that makes them worth $449?
Have a bit of a closer look at the spec sheet. Where is it you feel the 179 has better specs?
179 - 6000 count 3-1/2 digit largely industrial meter
DM3058 - 240,000 count 5-1/5 digit bench meter
As well as raw specs, there's a lot of things bench meters tend to be able to do.
- Connectivity options (e.g. LAN), 4-wire measurement, triggering options, etc
