Math only work in manual mode not auto!
It keeps the date even after I turn it off.
If you mean to set the time to be visible, then restart it and then not see it, then in the settings "Load Last" must be changed to "Last". Unfortunately, the factory settings default to Hide a Display time...

erk seeing this behavior tell me do not buy this until the FW is iron-ed out ???
a lack of check ups from Rigol
Damn ... I totally hate the zero leading digits, this is the thing i hated from the 34401a and up
For the size of this meter, while i do see the frame size, and not deep, since its a scope casing adapted to a meter,
i'm not impressed so far if the digit have these cross lines in them ??? wtf ? did they tried to imitate and VFD grid ???? :palm: :palm:
haven't seen any tear down of this meter ??

This whole new series of equipment is somewhat... undercooked, I would say. The scope is almost fine: it's inexpensive, it's hackable, it has good hardware (except the damn fan!), and its bugs and UI missing features/weird design choices are tolerable, because they don't defeat the purpose and are, generally, minor.
The DMM, however, seems to be a different story. It's not inexpensive for what it is, its specs are mediocre, and on top of that there are silly and immediately obvious bugs which should have never made it into the final product. Yet another evidence that there is apparently no QA team whatsoever at Rigol, or if there is one, then its work is disregarded and a sooner release is preferred over quality. That wouldn't be a big issue if Rigol collected relevant information about bugs (this forum alone has a vast knowledgebase on them) and published post-release bugfixes in a timely manner, but it does not seem to happen.
I'm not looking to buy a bench DMM (hope so), but if I were, I wouldn't be considering the DM858, not least because I own a DHO800 scope and wouldn't want to have another product engineered with the same attitude.

Why do you think it's a scope casing adopted for a meter..
that they release 3 products over ½ year, doesn't say anything about what a given case was intended for.
