Nice units, too bad SDM3065X costs too close to DMM6500 :(. Although, the latter is too big to fit my bench... Dilemma.

Here in the US its $729 vs $1095, that's 50% more expensive.

In EU it's like 820euro  vs ~1030, which is ~27%. Significant difference, but not that important to me. I also trust Tek a little bit more, they even specify 2year cal specs.

Hi,

Welectron offers them at this moment for 688,24€ and 806,72€ exVAT, only a 17% up.

Dear EEVBlogger,

someone there who could explain to me the difference
in HW version 02-02-00-05-00 vers 01-01-00-02-00 of the
SDM3065X device.

Is there a drawback baying a 01-01-00-02-00 device
instead of the 02-02-00-05-00 version, concerning
precision, stability or lifetime of such a device?

My second question concerning the SDM3065X is,
if there is a possibility to scale a voltage measured
via a current shunt in order to match the display.
Many shunts offered will have a 75mV full range
voltage at the terminals.
100mV shunts are difficult to find and they are
more expensive.
perhaps this could be done by the math menu?

Many thanks in advance for your anwser and clarification.

Markus

I have an SDM3065X. And an SDG2042.

If Siglent were a normal company they would have rack mounting hardware such that my meters could be mounted side-by-side, using a total of 2U. Not so, SDG-RMK is not of this world, it's the freak show of rackmounting kits. What is it whith chinese design, or rather the lack of it? Like the new Rigol SG:s, or ... SDG-RMK.
I asked about dual rack mounts a few weeks back and forgot to post about them.......they're coming !
Dunno any time frames but suggest you keep a watch on Siglent websites for them.
The new dual rack mount is listed as # SDG-2-RMK on P85 of the latest catalog:
Rackmount kit for two instruments , compatible with the SDG800, SDG1000, SDG1000X,SDG2000X, SDG5000 and SDG6000X series function generator and SDM3045X, SDM3055, SDM3065X digital multimeters

Hi All,

My SDM3045X compared to my SDM3055 and Fluke 187 has only on the DC range and mostly on the 6 volt range an diviation of 5.4 milivolt  :wtf:
now i want to correct this so i am looking for these files from Siglent

According to the SDM3045XService  Manual i need these python scripts

The python scripts include 8items as the following:
DCV_Cal: Calibrate DCV function
ACV_Cal: Calibrate ACV function
DCI_Cal: Calibrate DCI function
ACI_Cal: Calibrate ACI function
R2W_Cal: Calibrate 2 wire resistance function
R4W_Cal: Calibrate 4 wire resistance function
CAP_Cal: Calibrate Capacitance function
TEMP_Cal: Calibrate Temperature function

i have access to a calibrated Fluke 5522A so this must be appeltje eitje  :-+

thanks in regards

Mischa

@ doddemail
Welcome to the forum.

Before you consider calibration adjustments please check measurements again with concern over possible EMI/RFI and your DC source is accurate and clean without ripple or other interference.
The latest Service manual and datasheet with accuracy specs can be downloaded here:
https://www.siglenteu.com/resources/documents/digital-multimeter/#sdm3045x-series

You will need all the specified equipment to attempt calibration (HW and SW) and the Hamburg office should be able to provide you with Cal scripts on request.
https://www.siglenteu.com/contact-us/

I would provide them with evidence of the measurement errors to enforce your need for the Cal scripts.
Please report the outcome.

I take it there are no useful hacks to be performed on a sdm3045x?

What other use could there be for having free root access to the OS of such a device?

None that anybody's been willing to try.....but sure it's been considered here before now.

Does SCPI via telnet to port 5024 require root access to the OS? REALLY??

No.  Not for normal SCPI use.

There is no OS in these equipments so you can't access the OS! It's only a single "application" running.   :palm:

I wrote my question after seeing your post, tv84, about a set of ads files containing a script giving password free root access telnet to port 1101.
And that set included one for the sdm3045x.

n3mmr,

Please accept my apologies!! I should have stayed silent...  |O |O |O   (getting old...   :palm: )

Of course they have an OS. You can easily see that in the parsings:

You have scripts for the 3 models:

Don't fret! I've done worse!

Question remains, though, are there any useful changes or hacks that can be inflicted on a 3045x thru that telnet access?

The 3045X has about 99% of the features of the 3055.  I think there have been images posted of the internals of both units, but I don't know if there has been any conclusion about physical differences.  I know the 3055 has a fan and the 3045X doesn't.  I haven't delved too far into the configuration files, but short of exceeding the safe limits put in place ranges, I don't know that there is anything useful that can be done to improve the 3045X.

I can prepare a 3055 .ADS to flash on 3045 or vice-versa if anyone wants to try. Your responsibility, or course...

Visually the PCBs look very similar.
