Rigol DM3058 "Hold" trigger mode. What use is it?
JimStar:
Still not fixed... Not even one firmware update since then.
JimStar:
I wrote them again, and got some answers...
--- Quote from: me ---Guys, not even one firmware update since then. It's 6 years left, and this BUG is still not fixed! The only firmware available in the Rigol download section is still the same old buggy 01.01.00.02.03.01.00.
This is ridiculous, I've bought an expensive benchtop multimeter, and one of the important features of it DOES NOT WORK! The feature that even has its own button dedicated on the multimeter! The button that starts blinking indicating that it awaits for the measurement, and no matter what hold-percentage is set in settings (even if 10%) - it NEVER holds a measured value!
It's even discussed on well-known EEVblog forum:
https://www.eevblog.com/forum/testgear/rigol-dm3058-_hold_-trigger-mode-what-use-is-it/new/#new
Please fix this ASAP or refund my money!
Regards,
Jim

I answered with another message to that new ticket:
--- Quote from: me ---This is my post in the EEVblog forum thread, with all the previous (6-years old) conversation with your support about that well known bug quoted there:
https://www.eevblog.com/forum/testgear/rigol-dm3058-_hold_-trigger-mode-what-use-is-it/msg1977311/#msg1977311
It was promised to me that Rigol is working on fixing this, and looks like it was a LIE.
6 years is plenty of time to fix this simple bug. Please fix this ASAP, and release the fixed firmware finally!
Regards,
Jim

Let's see in a month if they finally fix this...
JimStar:
Good news guys!
I've just got a reply from Rigol, they've finally fixed it. Almost.
They sent me a test version of fixed firmware, and the "Hold" button finally started working! Unfortunately still 90% of times, where sometimes it did not stop listening and did not show any value and continued blinking... I needed to disable/re-enable it, and next time it worked. But even in this state it is already a big deal. Big thanks to Rigol guys who finally started working on this.
I'm not sure if it would be a good idea for me to attach a test-firmware here that they gave me, 'cause it was a file directly attached to their e-mail to me... So I reported them that in some cases it still doesn't work, and I'll wait some time if they fix this final minor issue... I think they will finally release a new version on their site. Let's wait for their answer to my latest reply/report first...
JimStar:
Firstly they were unable to reproduce the last issue. I've sent them a video in addition, and they've just answered that they were finally able to reproduce it. They said it will take some time to investigate if that last thing can be fixed...
Looks like these guys who are dealing with this now - are really responsive and dedicated to get this sorted out (in comparison to those I talked to few years ago). Really good level of support from Rigol now!
In addition I advised them to add BEEP to the event when the value finally freezes in the Hold-mode. So that when you're holding two small spots under the microscope - you'd know exactly when the measurement got already frozen on the screen and you can now remove the probes and finally look at the screen... Otherwise you're just holding the probes, counting inside your head, and praying that the value is already there when you decided that enough time already passed..;)
This will be a really cool device in this price range, if they finally implement/fix these two remaining things.
So lets wait some more... Hope they finally fix this final issue. And I really hope they add a beep to the Hold-event, which is important...
JimStar:
OK, Rigol fixed this finally. :clap:
They've really done a great job with that: not only the "Hold" button function now works, but they've even listened to me and implemented a BEEP when the value appears on the screen! So now it's very convenient to hit the points under a microscope and know when the value is ready to read on the screen.
The only minor thing still happens sometimes: when a contact flickering happens (e.g. probes slipped few times before finally hit the spots) - it may not hold any value anymore no matter how long the probes are held after that... Disabling/re-enabling the "Hold" button returns that to normal again, until next time contact flickering happens.
Rigol sent me a firmware update file to test it. After testing I asked them if it would be OK to publish this file on EEVblog forum - they gave me permission to do that. They just mentioned that: "but for the formal version on the web, we still need follow the publication process and wait some time".
So here is the firmware-update file attached: feel free to update your DM3058 with this fixed firmware (using standard Rigol update steps), but please keep in mind that I am not responsible for any of your troubles if you do so. ;)
