Siglent Bench DMMs SDM3065X, SDM3055 and SDM3045X

[BillB]

1. Change the size of text in dual display mode
4. Bug fix: The screen saving setup was lost after power cycle/reboot.

Nice.  Dual text display looks better now.

Hi,

... and where´s the Beef?
Recently I received a note that Siglent raised the priotity on bug-fixing the SDM3065X.
Q: did they increase the character size of the secondary display ?

Hello,

Im going to buy a DMMCheck Plus and I was wondering if I could use that to recalibrate my SDM3055 ?
In the manual, I only found information about automatic calibration with a professional calibrator but I don't know if there is a procedure to calibrate myself this DMM with precision voltage reference ?

Thank you for your help

There is a manual adjustment process being prepared for SDM3065X for those with very accurate references.
As yet it is not available and it is unknown if other models will also benefit from this manual adjustment process.

yes .

I don't use the dual display very often, but this is an improvement over the previous version.  Though, it would even better if they used the whole bottom portion, below the line by moving the range indicator to the left.

Just because of you ( ), I sold my SDM3055 and I bought a 3065X
The extra digit and accuracy will be usefull for my next project anyway.

Hello,

I have got a new DSM3055. I have the following Problems:

1)
I measure PT100 Temperature Sensors. If I turn the multimeter off and on again, it comes up with the last settings. So everything is shown for the PT100 measuring. But in the value it shows overload. I have to unplug and plugon the PT100 sensor again, than it shows the temperature without changing anything of the settings.

2)
I use the frequency measurement and display the Hz unit. Than I switch to dual display mode. The second unit is also Hz, how can I change this to period time?

3)
If I want to save the measurment to the internal or external memory the device crashes (doesn't react do any button) and I have to restart the device.

Hello,

I have got a new DSM3055. I have the following Problems:

Which firmware version?

[mrprecision]

The Version is v1.01.01.20R2

[mrprecision]

3)
If I want to save the measurment to the internal or external memory the device crashes (doesn't react do any button) and I have to restart the device.

I figured out if I save the data out of the memory to the USB Stick it works once, than never again. I have to delete the files from the usb drive, than it works again.
It is only possible to save one reading in a directory, if I store more values, the multimeter crashes.

Continues recording is not working at all.

[mrprecision]

I measure PT1000. This works fine. If I turn off the DMM and turn it on again, it shows overflow and I have do disconnect the PT1000 and reconnect it again. Why is it not working direct after reboot?

SDM3055 owner.. good value for money, but the probes it comes with, wow are they ever complete garbage. I know they aren't gold plated Probe Masters, but wow... they're miles worse then any other leads. Measuring resistance it's all over the map.

I had contact with Siglent, the will fix the problem. I also can not store the values of measurments to a usb drive or internal memory more than once. They will also fix this problem.

This should be handled with outmost priority. After LM399 burn-in (with is done by buying an SDM3065X and powering it on), I want to adjust the meter back to spec. But Siglent does not publish the procedure, only references an obscure python script that isn't official.

Gimme an adjustment procedure and some ordinary SCPI commands to execute, and the paperweight may be of some use again.

Sorry but the manual adjustment procedure is still not ready and you may have noticed SDM3065X firmware update is also overdue. Maybe to permit user adjustments the firmware must have provision for this and also save the factory Cal so it can be returned to factory settings in case a mistake is made.
The factory is on spring break for 2 weeks now and when I last asked about manual adjustments in Dec19 Siglent was still solving issues with its implementation.

Hi there,

have my new SDM3055 since yesterday.

So far so nice, but I have a strange problem.

With every attempt to save something (whether setups as xlm.xx or Save Screen) the device freezes.
At first thought it might only affect saving to USB, but this behavior is also evident in the internal memory
(and this even without a USB device inserted).

The device then no longer responds to anything. Then it only helps to turn it off and on again.

Also, I haven't really understood how Save Screen should work.
(Ok, but I could not test that the above problem does not allow this).

Addendum:
Firmware is 1.01.01.20R2 (was already available when purchasing).

[klausES]

File manager operations like creating new folders, renaming, deleting is possible. For files too.
But when I go to save it freezes. 

No one has an idea why this is going wrong?!?

In dozens of attempts, I have now once managed to save without crashing.
Therefore it is not clear to me whether I am doing something fundamentally wrong with the operation ? 

PS.
It also happens when I do this via Easy Dmm (Control -> Virtual Panel).

[klausES]

It also happens with "Acquire -> save Reading -> U-disc record" if you stop recording and want to save it.
Frozen (hence a photo of the screen, no own screenshot).

At the very moment when the popup success came it froze.

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.

[tautech]

klausES, mrprecision

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

From the manual:
(3) Check if the capacity of the used USB disk is too large. The Multimeter is recommended not to use USB disks which exceed 4GB.


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.

[klausES]

...Have you tried other USB sticks ?

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.
