This meter is not ready for sale, Rigol need to recall all sold units pending a fix. There is a safety issue here. Thank you Marcel for your work in bringing these issues to wider notice.
Agree, it is not ready for sale. I hope that those videos will help to inform other (potential new) users and at the same time I hope that I can put some pressure on Rigol in order to release new descent hardware quickly. They should stop selling the current ones in stock as I advised my seller. Thanks for your reaction !
@@marcelmostert3081 Ja jammer dat de verkoper (ik zal geen namen noemen 😁) ze nog steeds verkoopt. Ik had mijn oog ook laten vallen op de 858 maar ik haak voorlopig even af 🤔
@@M-P-X ja, nu zeker niet kopen. Ik ben heel erg benieuwd wat ik terug ga ontvangen. Overigens heeft de verkoper wel een policy dat ze automatisch stoppen met verkopen bij te veel returns. Kennelijk is er of weinig verkocht, of niemand vind het probleem erg - mits je het weet.
Unfortunately, Rigol has informed me recently that there is no clear outlook when the solution will become available (after almost 3 month's in 'Repair').
Eu estava prestes a compra esse DM858, mas graças aos seus testes mudei de idéia. Comprei um Hantek HDM3068b e estou muito satisfeito com ele, também tenho um OWON XDM1241. Um abraço.
Hi, thanks. Meanwhile I am working only with my OWON XDM 🙂. Nice to hear that you have a Hantek and not the current buggy DM858. Are there really no issues with the Hantek, is it 6.5 digits (HDM3065b) not 3068? greetings
My Owon of ~110 Euro - which I also used in my videos - is working fine without problems since years. But I like the DM858 form factor with its additional features. At the time I bought it (March 2024 originally) there were no reviews yet, unfortunately...
@@marcelmostert3081 Формфактор не очень удачный для полки. А на столе его иногда некуда ставить. Спасибо за качественный обзор, тоже хотел его купить из-за наличия четырёх-проводной системы измерения сопротивления, но наверное куплю OWON XDM2041
I ordered this device, let's see what I receive. This hardware problem has a trivial reason. The problem is that in automatic or manual mode with an overload, the protective zener diode at the input is triggered. Theoretically, this can be corrected programmatically by lowering the switching threshold and the sensitivity of the overload detection algorithm. This will reduce the range by 100 instead of the stated 120. But this will be a solution.
I am interested what kind of device HW version >1.01 ? you will receive. According to R&D from Rigol it is an hardware issue. I am still waiting for HW update as my DM858 is still in "repair". The Repair department stated that Rigol HQ is working on a solution. In October I expect an update. However, if you receive your device, please let me know the status. Your solution might be correct, but it would make this device a 5 digit (and not 5 1/2 digit) multimeter after a SW fix or config change. Although I find the current 120.000 count already limited compared to competition which has 200.000 count and called it also a 5 1/2 digit device.
@@marcelmostert3081 HW: 1.01, SW .20rev, System Version 1.5.3. Auto switching works, but as expected at 100,000 instead of 120,000. The impedance problem persists.Also, I didn't like the error. and no digit style settings. Sent back. I took it to Amazon. I look at other options.
I know is a little bit annoying when spent some hundred bucks and the meter doesn't work perfectly, i got same problem few years ago with other brand. But, very important thing all that issues can be fixed with some software updated.
R&D of Rigol already confirmed that (at least the Impedance in Autorange) is a hardware issue. So my hope of a software fix is now very low. That is the reason I shipped back the DM to the seller. I guess they made a hardware design fault in the analogue front end circuit. May I ask which type of problems you had with the other brand?
@@marcelmostert3081 the hardware problem it's a very bad news, i agree with you send it back to the seller, no doubt. I had some troubles with a dc electronic load with firmware bug, and to solve all the problems they wrote two (maybe three) update, than it start to works as it should. But to be honest when you buy a piece of gear ( for thousand and more Euro) and can't use it from the beginning, it's not a good deal.

I was planning to order this multimeter, but I think i am gonna wait. Thanks for the video. Cheers.

Thank you sir. I was going to buy one too, but saw your review in time.))) Do you have any positive news from Rigol?

A lot of excellent works!
Many thanks!
I ended up buying a OWON 140$ CAD and have 0 issues lol
