klausES, mrprecision

Have you tried other USB sticks ?
Can you confirm they are FAT32 formatted ?

When I next have a SDM unpacked I'll check for this apparent bug.

It is not the problem of the USB stick and the formatting. Also the same problem happens if you save the file to the internal memory. If you delete all csv files form the memory, you can save once the data do the USB stick.

Siglent answered me regarding this problem:

It does be a issue and it was forwarded to our R&D department. The related engineer will fix it and this need some time. Please wait for a while.

Yes, FAT32 and also tried also sticks that only had 2GB.

But since the error also happens when saving in internal memory,
(and no stick is inserted) it shouldn't be a special USB problem.

Could it be a bug in the latest current firmware version (1.01.01.20R2) ?

If this problem had existed for a long time, even with older versions,
i think would there have to be more people who would have reported this?!?

Do I understand correctly that a csv must not be present in the internal memory?
Not even if you want to save to usb?

Definitely a bug.

We can only hope that Siglent will fix this as soon as possible.
I was really looking forward to the device (and therefore I will not make it bad, it is not bad), but it does cloud the joy a little.

Would have liked to try 1.01.01.20R1, but this version is nowhere to be found online.

Has someone happened to have the ver. 1.01.01.20R1 saved for itself and could it be sent to me ?

Otherwise I could only try the older 1.01.01.19 or 1.01.01.16R2.
However, these old versions lack some important functions.  :-\

...Because who knows how long it can take for the bug to be fixed ...

Ok, just tested with 1.01.01.16R2 and with 1.01.01.19 (unfortunately I didn't have 1.01.01.20 and 1.01.01.20R1).

With these two older versions, this problem does not exist.
Saving works perfectly with these.

So clearly a bug in 1.01.01.20R2  :'(

That would be good. Better than if maybe one person reports it and it goes down.

Thank you for your attention to Siglent users.  :)

I noticed another mistake.

If you select "Mode Continuity" for the first time (after switching on the device), Threshold (default 50 ohms) cannot be adjusted.
The digits in the display do not react to higher or lower positions with the cursor up and down keys.
The cursor itself cannot be moved vertically in the digits.
Only when you switch to a completely different measurement (it doesn't matter, Volt, Current or whatever) and back to Continuity does it work.

Whether this really is related to 1.01.01.20R2 (I only noticed that this was not the case with 1.01.01.19) i have to examine it later more closely.

It would be good if someone else tried it out with their SDM3055 and the 1.01.01.20R2.

Siglent has changed a lot in relation to the earlier SDM3055.

No more rust on the cut edges / punched edges.
PCB changed (components that have been subsequently soldered on now have their own soldered joint in the pcb).
The quality of the bcb soldering (Dave complained in the 2015 video) is now flawless.
Siglent replaced the old fan with a higher quality one (lower speed, quieter bearings, quieter blade shape, diameter now 60x60x12 mm).
In addition, the voltage for the fan was reduced to 9.4V.
The plug connections flat plugs (e.g. earth) are firmly attached with clamping force.

Negative changes:
The sd card slot has been rationalized away.

Unfortunately, in order to further reduce the noise of the fan, an unsightly remedy has been used.
The fan has been installed "upside down", which makes it even quieter since it sits so close to the grille of the cover
(since it is now no longer on the suction side but on the pressure side of the grille),
but this has major disadvantages in terms of flow technology within the housing.

If it had been installed with its suction side at a distance from the grille (8-10 mm would have been enough),
it could have been installed the right way round without amplifying the noise.

I will change everything (already started) and build a temperature control with heating and ventilation,
adjustable from 20-35 degrees Celsius in steps of 0.5 degrees, the set temperature then remains with an accuracy of +-0.25 degrees.

Or....try it without a fan like the SDM3045X.  :popcorn:

The sd card slot has been rationalized away.
AFAIK it was only used to flash the OS and FW into these units at the factory although later it has been also used for early FW version boot freeze recovery but now production units run later FW that allow for the noninvasive USB recovery it's a good thing they are now omitted to remove the temptation to owners to muck with the SD card slot and potentially brick the unit.  ::)
Yes it happens !  :horse:

You are right, a possible guide to recovery in the firmware is of course the more elegant solution.  :)

Definitely not.  >:D

Has someone reported this to Siglent to fix it?

I have reported "both errors" to the support of the dealer (Batronix here in Germany).

I was promised they would contact Siglent.
At the moment "it is said" that no one can be reached in China by February 20, or no reactions are expected before that.  :-//

Nope, but they're working remotely from home so until they get back to the labs all they can do is record issues and deal with them later.
I've reported them too.  ;)

Thank you.  :)

I also reported it directly to Siglent yesterday.

(I was just wondering why nobody should be available in China at the moment ? Whether it has anything to do with the virus ?).

Everything is affected by the virus. Everybody is being extremely careful and the authorities have restricted many non-essential business operations.

Unfortunately, another problem with my new SDM3055 crystallizes out.

It is now the fifth time that it freezes when it is on for a longer period of time (without a key being pressed during this time).  :-\
Whenever it runs unattended for about 2 hours or more.

The current measurement then continues (the values continue to update on the display)
but it then no longer responds to any key inputs.  :-[
It doesn't matter what type of measurement.

The only thing that remains is to switch it off and on again.

I can't say yet whether this also has to do with the 1.01.01.20R2.

First of all, I only have the opportunity to try it for a few days with the 1.01.01.19 under the same conditions,
whether it is there not the case or the same...  :-//

It’s not yet 100 percent safe because with this thing,
which does not always and if occurs after 1 to 2 hours, cannot completely rule out coincidences.
Have now tried two days and nights the 1.01.01.19
It did not occur there.

But only two days two nights don't prove this, now what is certain is that it is back on 1.01.01.20R2 this morning and it froze after 1.5 hours...  :(

Now I'm trying to find out whether the error may be caused by the screen saver or by "waking up" from the screen saver.
There the SDM3055 behaves very different when waking up, worse than e.g. the SDG1000X series in which this was better solved in software.

It is very annoying. Restart, restart, restart...
Slowly, along with the other three mistakes, the fun passes.  :-[

But just noticed one thing.

He then no longer responds to any key ... but in EasyDMM I was still able to operate everything in the virtual panel and he did it in real life.
After that, oh what... he could be operated again using the buttons on site.

I mean I had tried it before and it didn't work.
Whether this was an exception. no idea.  ??? at least this was possible.

This knowledge might help people at siglent troubleshoot ?!?

Yes, twice again today ... after freezing (no more reactions to front buttons)
it can be operated functions using SCPI commands and then again also with the front buttons.

It seems to me that when wake up the screen saver
the controller (or the reception / response of the controller) to the key matrix does not wake up.

In my opinion, what do you all mean, this behavior increases the likelihood of a software error in the latest Frimware
(and diminished, so I hope a probability of a hardware error in my device) ?

...I had the same problem and I have contacted Siglent Germany. They could reproduce this error and wrote me that this is a bug. This was on the 2019-01-19. So we have to be patient.

If you have no csv file on the stick, you can save the data. If there are multiple csv files on the drive, the device crashes.

Since there is still no solution to the save problem ... a short request:
Is it a typo or is it really over a year since you reported this to Siglent  ?? :palm:

When Easy DMM is connected or other SCPI application is connected to DMM , it will switch to remote mode wich is signaled on upper right corner on screen (REMOTE) .
In this state the physical keys are not responding to pressings.
You must disconnect first from it and the DMM show LOCAL in upper right corner.
Maybe you can check this ...

Didn't mean it so...

Only when it is frozen, only then did I start to test e.g. EasyDMM and only then can the front keyboard be reactivated.
Because on the device itself in this state, no chance

No software is running during the operation in which he freezes at some point.

It just happened again.

I have been using the SDM3045X for a long while and I really like it.

There had been a few issues and a few lacking functions, but Siglent is very responsive about it.
I had been in contact with them for over half a year and they sent me updates on the development cycle and preview releases  ;D

The features and fixes in particular have all been released and I have highlighted the ones I was involved with in the attached changelog:
