Important!:
For SDM3045X only: After now, until further notice, only valid data sheet is rev.: EN_04A
https://www.siglenteu.com/download/2587/?tmstv=1684220107
The datasheet has some "incongruences"
"Product Overview
SDM3045X is a 4½ digit digital (
60000 count)"
But in the...
"Main Features
Real 4½ digit (
66000 count) readings resolution"
I believe the later is correct.
And they still show a picture of the rear, with the "Extension Card Option", that I think it's non existente.
OP updated with a typical recovery procedure video for all of these meters and further comments about recovery added.
Running the latest firmware much reduces the need for any such recovery procedure and its inconvenience.
It´s done, I´ve ordered 4pcs SDM3045X...
Hello, I'm a happy owner of SDM3055-SC
Regarding firmware upgrade from V1.01.01.25 to V1.01.01.27R2 I have spotted some bugs that I would like to know if I'm the only one :-)
After upgrade I have problem with USB and VX11 connection using SC card on SDM.
I can connect and scan voltage but when I start scanning Temp or capacitance the scanning part stops (hang) before execute first measure and I have to restart windows 10 and the SDM.
I have tried this on two win10 pc with exactly same crash on both (using EasyDMM 1.02.01.03)
Before upgrade I could connect and use USB and VX11 and scan Temp measures
The reason for why I'm upgrading is that SDM doesn’t show me accurate Temp measures, I have 12 termo devices to scan and they work right on my FLUKE but not in SDM. In latest upgrade I see some custom features that might help me out.
I have also noticed slower USB communications during voltage scanning. I get communications error 21400 and “An unhandled Microsoft .NET Framework exception occurred in [21400] EasyDMM.exe”
I also feel that accurry of type T Thermocouple for range -60 to +260 celcius is showing higher levels of +2 to +4 decreses on TITS90.
On SDM the file8 TITS90 always jumps back to File1 BITS90 after changes to other measures like voltage and power off and on.
Has anyone tried to use Scan Temp with new firmware 27R2 ?
Thank you all for very helping information in this thread :-)

Arrived...
Quick check after unpackaging, done the firmwareupgrade on all four (all got the previous version), now they´re ready for external calibration before we can use them.
Nice building quality, I´m playing with the thoughts to buy one or two for my home equipment.
Also nice and never seen before, the warning tape on the mains socket...Good!

2 out of the 6 Siglent units I bought in the last year came wit this. Maybe people are either, blowing them up or, complaining they are not working, too often for Siglent's liking. These would be people that should not be buying this sort of thing .. perhaps.

Always Siglent equipment with linear PSU's come with warning tape to set the correct voltage over the IEC socket.
We set them to NZ 230VAC when doing our PD checks.
China is 220VAC so that's what everything comes set for however I do remember some US member here snagged one cheap from a US seller as not working.....it did and perfectly when the selectors were set to 110VAC !
Mine have all come set to the right voltage. Perhaps my supplier ran out of the stickers for a while as I bought the first 4 of them over a short period of time. I actually don't know who does the actual setting, Siglent NA or my local dealer.
So, yeah .. it is as it is.
I have a sdm3065X that I got about 3 years ago, it's been my main DMM, hard to believe it's that old already. How would it compare to then ? I'm in no rush to have it cal'd, not for what the locals charge.

With the latest firmware a simple user cal was added so if you have some
accurate standards you can now more easily tweak it for it to be more precise and if you bungle that simply return to the factory cal.
Defpom has an investigate of it:
@Tautech
Such a question out of curiosity. Does Siglent have any service that can perform factory calibration (of course, we are talking about a paid service in some time) ?
I would think the distributor for your area should be set up to do calibrations.

AFAIK both Siglent Germany and USA have inhouse Cal facilities, US certainly do but you need double check with Augsburg, Germany.

Hi
Has anyone tried V1.01.01.27R2 for SDM3055 ?
This software is very troubled when using scanner card.
Please read my prev post from May 30 if you have tried this firmware update.
Thanks
Daniel
Is there any way to report firmware bugs to siglent? On my 3065X I noticed that if you use the hardware buttons to set the voltage range to a fixed 20V then the Impedence setting is not there. If you use the software buttons under the screen to get there you can select the high impedence mode. For the lower ranges it works as it should.

This is perfectly normal as the Hi-Z mode is only available up to 20V (on the SDM3065X model, in other models up to 2V). So you cannot logically set it to auto mode which covers all measurement ranges including those that do not support Hi-Z.

It doesnt work on manual range. It is depending on wether you use the exclusive range buttons or the softbuttons to get to the manual 20V range. The first one does not give you the option, the second one does. For the smaller ranges it works as expected. Here is a video to show it:

Anyone know the max safe output from the front-panel USB port ? I have an HP Prime calculator, that for some reason, won't charge from my mobo USB3.0 port, or any other (maybe the cable), but it did from my SDM3065X.
But I didn't want to leave it, it recommends a 2A charger, even a lightning USB3 port I think.

2A is a lot to ask from a mobo USB port. I think most mobo USB ports are around 0.5A max output. I'd say your DMM is an expensive power adapter in this case. 😉

Not off the top of my head however FYI, a member here with a Siglent DSO had the USB power fail and the scope behave strangely due to the USB port overload protection. After a reboot things returned to normal.
I can't say/don't know if the SDM3k product line uses a similar USB port overcurrent protection scheme but can find out in a day or so.
Yeah I should get an adapter board or cable for USB back to 5V directly from my computer's PSU. I have chargers, but none of them are very good, and not compared to a real PSU

If the only purpose is charging, I would leave your more expensive equipment out of it. I use these:
https://www.amazon.com/gp/product/B00P933OJC/ - that does up to 2.4A per port...and it's $20.

@delvo This way I don't switch ranges (I've always used the Range button below the LCD screen). In fact, we have a bug in the firmware, probably related to other models where the HI-Z mode is only available on the 200mV and 2V ranges. However, it is missing and turns off in the 20V range.
@Tautech Can you report another SDM3065X bug to Siglent? This applies to the lack of HI-Z mode (10G ohm) when measuring DCV when we switch ranges with the "+" and "-" buttons, it occurs on the 20V range. However, using the button under the LCD screen to change the measuring range, everything is OK (HI-Z mode is available on the 200mV, 2V and 20V ranges). Just like in the video attached earlier.
@delvoI personally reported the bug to Siglent and it was acknowledged and forwarded for resolution. I have to admit that this time communication from Siglent Europe awas exemplary. The error report was sent to other company branches (Siglent NA, Siglent China).
It remains to wait for the new software, we'll see how quickly the problem will be solved this time (I hope it won't be another two years
).
Our four SDM3045X are back from external calibration, "flawless"...
When I´ve erased some "critical parts" (Names, Adresses,etc), I´ll upload one or two (they are all very close together) protocols here, just for information.
