Rigol DMM DM858 comparison thread
coromonadalix:
i think the dmm chip seems to be some Hycon or Fortune ... the main cpu is an allwinner A40 SOM, so for sure it must run some nix OS ....
Ok touch screen and some functionalities could be good, but it suck so much just seeing it working on Youtube
I trust more the 344xx series than this puppy, even the Owon 55k count meter based on a Hycon too loll, at least the bugs are known on the Owon ??
yeah Rigol smell like toys ... Sorry Rigol "up your game" a bit please

Yeah, I'm starting to feel the same way.
The DM858 did not meet my expectations.
Weak DMM, few features.
It's not worth buying in its current state.
Rigol would have to make a huge improvement to change my opinion.
It doesn't know much for its price, I would have been better off with a Brymen.
I'm starting to get the feeling that the bug above is going to be a hardware issue.
When cold, it is between 31V-41V, after warming up it is between 28V-36V. So don't take it apart, the warranty will still come in handy.
I wonder if the big fuse somehow blows, then how do we replace it without losing the warranty?
J-R:
This does not surprise me, bugs are Rigol's calling card. I would expect them to address something this serious with an update or warranty service.

For this problem, i force the cal center(s) to put sticker on the main casing, ie: not on case screws or 2 parts case joints ..... i'm sick to break a seal because of a damn blown fuse(s)

They didn't make a small door on the back for that fuse out of laziness or sloppiness...
The warranty sticker sucks, there's a plastic film on the top and some silvery stuff on the bottom, you can't pick it up in one piece, something like what's on a scratch card. |O
