Thanks for the heads up tautech - I agree the release notes are slim...
I've done the update, no problems.
I haven't fully re-characterization the meter yet, but I can confirm the .csv saves now work.
Why would a Chinese business invest in software when anyone can trivially copy it and use in their own competing products? Clearly there is no incentive to have good software, only exactly as much as is needed with the worst pain points alleviated. Same with hardware designs, with a strong bias for parts you can get cheaper than anyone else. Same with manufacturing; the only differentiator is whoever can manufacture, box, and ship product at lowest cost. Obviously this greatly disincentivizes investing enough in software or hardware to stand out - in other words, there can only be commodities.
SDM 3055 just tried with 1.01.01.22:
EasyDMM no longer works properly.
The rest of EasyDMM is still running, but the Control Panel no longer works.
(3055 switches to Local when the EasyDMM Control Panel is called up and does not respond to Control Panel commands).
Units for temperature measurement are no longer C ° and F and K, but all three possible options are only displayed as K (Kelvin).
Only K is displayed in the selection option and in the operating display.
Flashed back to 1.01.01.20R2
EasyDMM works again and C °, F, K available again...
Klaus - thanks for starting to dig into this.
I haven't had enough time yet to evaluate myself due to workload.
Your findings are concerning...

They are indeed.
klausES report confirmed
however I find it just as disappointing that User Cal/adjustment has not been added like for SDM3065X.User Cal/adjustment has been added for professional users with quality references. Procedure available only on request.
Email sent to Siglent......reply received.
Bugs will be promptly fixed.
I updated my SDM3055 to version 1.01.01.22 to check the updated trend chart. Sorry to see the bug I reported a few years ago is still present. The image below shows an example of a ramp with a constant period of 1000 seconds. In the trend chart the time axis is still not correct, the older data is shown compressed.
![Siglent Bench DMMs SDM3065X, SDM3055 and SDM3045X](https://www.eevblog.com/forum/index.php?action=dlattach;topic=36689.0;attach=1149940;image)
What I think happens is that when the buffer of 10,000 datapoints is full, some of the datapoints are removed, but the sample time with which new data is added remains the same. After data is removed from the buffer, the samplettime should be lowered so the new data matches the old one. For example: when you sample 10,000 points once per second and the buffer is full, you can remove half the samples. But from that moment the sampletime should also be halfed. The SDM3055 keeps sampling at the original rate which causes the old data in the trend chart to be compressed relative to the newer data.
I have a beta of 22R1 that addresses the EasyDMM and temp issues.
9MB so can share it by email only...PM me.
Trend chart issues are under investigation.

Hi Klaus
Have you tested the 22R1 beta firmware I emailed you ?
Anything to report ?
Is it fit for release ?
Any news on the release of 22R1 ?
Any news on the release of 22R1 ?
None. Last I heard Siglent were trying to get additional stuff sorted for a bigger release.
If you’d like 22R1 send me your email and I’ll send it to you.
It’s been checked by a couple of members and got the thumbs up.
New firmware versions for SDM3045X, SDM3055 and SDM3065X.
Please select the version dated 2021-02-07 for your SDM from this page:
https://int.siglent.com/download/firmwares/?CateIdss=5Release notes
SDM3065X
Version V3.01.01.08R1
Fixed some crash faults about U disk Save &Recall.
Fixed some bugs about “acquire” function.
Improve the trend display function.
Fixed some bugs about communication with EasyDMM
SDM3055
Version V1.01.01.22R1
Fix some unit faults of 22version.
Fixed some bugs about communication with EasyDMM
SDM3045X
Version V5.01.01.06R1
Fixed some unit faults in 06 version
Fixed some bugs about communication with EasyDMM.
Nice!
The measurement functions and units are back on the 3055's display again!
I was about to go back to a former version.
Thx for giving the trigger for us here, tautech!
In the Version for the SDM3055 (V1.01.01.22R1) I now can store multiple times data to a USB drive, but I can not SAVE the settings, than the device crashes.
I also make some changes (Screensaver to 1h) after the next boot it was still set to 1h, but later it was set back to disable? Why?
For the SDM3045x there was alo an intermediate version, which possibly was not public:
2021/1/8 5.01.01.06
1. Fixed some crash fault about U disk Save&Recall.
2. Fixed some bugs about “acquire” function.
3. Improve the trend display function.
4. Update the software platform code.
So these fixes should also be included in the 5.01.01.06R1 version
As I did not find the term "downgrade" here in this thread, may I ask if I am able to downgrade to an earlier firmware if the latest firmware version surprises me later with some hidden, not-immediately-visible problems?

Normally the release notes mention if FW rollbacks/downgrades can not be done.
As this is not mentioned expect an earlier version to be able to be installed without problems.
There were errors in version 22 and several members went back to an earlier version until we got 22R1.
Should there be any problem the recovery package installs earlier firmware and we can currently use it as a solution to your concerns if required.
Hi there.
I just purchased an SDM3055 brand new, with a cal date of 01/19/2021, and just upgraded the firmware to the new version mentioned above.
My question is, does the instrument now reboot by itself after the firmware upgrade, cause mine does. It works just fine, and shows the new version, but once its done updating, (progress bar moves) it reboots on its own. It came with 1.01.01.20R2. I upgraded to the next one, and now this new version. Both upgrades behaved the same.
Is this a new "feature"? Its not mentioned in any instructions that I have read, including the ones that come with the firmware.

Welcome to the forum.
Yes auto reboot after FW installs is standard and depending on the model range it may happen a couple of times.
Thanks for the info, much appreciated. I came here looking for help and info, and found it!
Siglent might want to update their instructions, as it might tend to throw new owners for a loop, wondering if something went wrong!
The temp labels are back to normal, instead of KKK!
Hi,
at least with the 3065x it truncates the measurement values of Min. Max. Avg. in logging mode on the display.
Are there any infos available as to if and when this ´bug´ will be resolved?
In the end its a 6.5digit DMM which only shows 4 digits in this mode.
![Face Palm :palm:](https://www.eevblog.com/forum/Smileys/default/facepalm.gif)
... and its not due to running out of display estate area.
The Bug is really annoying when you do calibration work and need the precise figures.
regards
Calvin
