- Rigol DM858 E (un)boxing - recap before sending back this faulty benchtop multimeter device to Rigol
- some extra DCV failure test
- Clock issue
- Updated Bug / Wish list
- Boxing
Hello and thank you for this latest video on the problems with the DM858E and DM858 models. I've just done the same test with my DM858 and I still get the same bug when I'm on the 1 volt gauge in manual mode. I haven't had time to look at the clock problem.
As for the system version, apart from the different serial number and calibration date (2021-01-18 for mine), all other parameters are identical to yours.
Looking forward to the return of your DM858E from Germany after Rigol has inspected the problem. We still believe!
Hi Frank, thanks for confirming the same 1 V bug and other parameter settings. As soon I have my DM858E back I will retest and publish a TH-cam video of it. I hope also that Rigol is working on the other SW bugs meanwhile.....
Thank you Marcel for this news. The hardware is now H1.01 on the model you're about to receive in DM858! Let's wait until you've received your new DM858 to check the firmware number too. I'm not sure what to make of all this... Have a good week and thanks for your message.
Hi Frank, I received my DM858 yesterday. This evening I made short video of it. It is indeed with HW 1.01 (while same .20 SW). I think they change some components in the front end regarding the overload protection. Have a nice evening!
Hello Marcel. I'm sending you an interesting link about the DM858. The same applies to bugs. Best regards.
Hello Frank, thanks for link. Meanwhile I had an update from my supplier (Eleshop). They received the 858E back from Rigol Germany and they did some test at the location of Eleshop. But they didnot check the DCV autorange test. They sent some picture where I saw Hardware Version 1.01 (so not 1.00). I was happy and I thought this might be solving the DCV autorange problem. As this was another 858E device from Rigol Germany (different serial number then my original one) I ask them if it was possible to change it to a 858 (without E) prior sending the 858E back to me. That was possible after paying the price difference. But now I am waiting for the 858 because it was not in stock. I asked them if the 858 has also HW 1.01. They were saying it will be the newest HW. Let see what it will be. Hopefully I will get the 858 end next week (my guess). Best regards
Any progress on the fix for this meter?
It seems to be that I can expect a new meter on July 6th. I will make a video of it.
Having just received a DM858E here in the UK, I can confirm the same fault at higher voltages, 35v, in Auto. My Hardware version is showing as 1, and software as 1.0.0.20. It is very odd that Rigol could release a meter with such a fundamental problem, and then 6 months later, the problem remains unfixed.
Tomorrow I will get a new DM858 from my supplier. I will let you know if the problem is still there. It should be coming with the "latest" hardware version - but I am not sure what that means. Note: I know there is at least one DM858E out there with a HW 1.01 version. They were planning to ship it me, but I asked if I could upgrade it to a DM858 non-E version, assuming it would contain HW 1.01 and that it would fixed the DCV autorange failure. I didn't got a clear confirmation about that - except the price difference bill for the non-E version, that was clear :-) . So I am little excited for tomorrow.
Let us hope that Rigol have identified and fixed the problem on your updated meter. Good luck.
I’ve noticed another odd thing about the meter, when measuring ohms. In many cases the autoranging shows values as a decimal of the range, ie 330 ohms is displayed as 0.325K or 270K is displayed as 0.268 Mohms. Switching from Auto to a manual range doesn’t work as an Overload message is displayed for what should be the correct range. It’s not incorrect but not as convenient to read as 330 ohms or 268K ohms, as my Fluke meter displays. A poor design decision. I hope you’re having better luck with your replacement meter.
HI Did you receive any update from Rigol about this issue?
Hi, not yet. I expect an update within 2 weeks. Once I have my DM back I will post another video with the results.
can you recommend it for his price ($350-400)? for me too hard to find siglent or spent 700$+ on another device
Assuming Rigol will fix the DVC issue, I can recommend this meter if you like the formfactor (big screen) /GUI/mouse interaction. Alternatively, I would suggest a SDM3055 of Siglent, but if Siglent is difficult to find, then why not this Rigol. I will do make an update of the YTvideo of the Rigol after they return my device. Maybe you can wait?
@@marcelmostert3081thank you. I'll be waiting for your updates. I’ve been using the DHO804 for six months now and I’m satisfied with almost everything (there are a couple of bugs, I couldn’t reproduce them), so this form factor is convenient for me.
Would you buy the siglent over this meter? I like the form factor but it seems many issues

Thanks for your great video. I wanted to buy it first. But then I bought a Siglent SDM3055. Luckily that was the better decision :)
I couldn't agree with you more. I would have done exactly the same given the too many bugs encountered on this DM828(E).
Yes indeed, the SDM3055 was also on my shortlist. I couldn't find a TH-cam review for the Rigol at that time. So it was a educated risk :( Question: Can your SDM3055 also displaying a negative Overload. E.g. " - OVERLOAD" and "+ OVERLOAD" ? As my Rigol is displaying always "OVERLOAD" for both cases the corresponding Trend Chart is wrong. But I am curious to see how other brands handling that situation.

Ik wacht wel op HW versie 2 🤔
Ja, dat is geen gek idee inderdaad.
