All the 1 year accuracy specs are listed in the Datasheet, I'm interested to know which measurement ranges fall outside those specs ?
http://www.siglentamerica.com/USA_website_2014/Documents/DataSheet/SDM3055x_DataSheet_DS06035-E02B.pdf

My SDM3055 is off by around .150 Volt at 5 Volt range. I've had it for around one and a half year.

If your reference is as good as you say it is then indeed that seems an excessive error.
Let us know how you get on with your contact to Tech support, the guy I normally contact is off work until after the Chinese New Year But he has sent me sample EasyTest scripts so I'm sure we can get one for you.
PM me if you wish.

SDM3055 do not have 5V range at all. Most near 5V is 20V range.

Tell us what is your reference voltage and guaranteed maximum error. Then tell us what SDM3055 show, exactly,  when it is well (30min) stabilized to 23 +5 celsius environment and settings as deafault.
Then Max, Min, Average and SD, use example 1k samples and slow measurement..

0.15V error @5VDC is really gigantic error.  Some things are now badly skewed.
My old Metrix 202 analog is more accurate.



But, if it show 5,00000V reference DC using 20V range so that result is 0.15V off it really is like fail.
If practice and theory is not equal it tells that used application of theory is wrong or the theory itself is wrong.

It would appear that RS Components have adopted the Siglent SDM-3055 as their own, it must be special particularly at the prices they are asking.   ??? :o ::) :P

How can I make a 4-wire connection for the Pt100?

Just as you would for 4 wire resistance measurements.

However there is only mention of 4 wire temp measurement in the Datasheet and I couldn't find any mention of 4 wire temp measurement in the User manuals, old or new.  :-//

Yes in the mean while Siglent has fixed the price, we will be happy to offer discounts code in case of interest.
Would you like us to test the unit and make a video?
What would you like to see?
I have one unit sitting on my desk

They fixed the price? I'd say they broke it.

I understand what you mean though but for me the SDM3065X just became a lot less attractive.

BTW, I was looking at the accuracy specifications in the datasheet for the SDM3065X and noticed that they looks remarkably similar to those for the DM3068. There doesn't seem to be a single digit difference anywhere. Are these sort of performance numbers just mathematically calculated, tested and verified on actual instruments or just copied from the competing products datasheet?

Here's an example of the DC Voltage range

At that price you better buy the real deal: a Keysight 34461A
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

I agree.
The "fixed" price for me was a big disappointment !   :palm:
I don't find it so competitive anymore.
Previously (at 539€) i was a prospective buyer, but now ...
I will wait to see the value of the expected SDM3055X-E and if they "fix it" too, i will go for something like 34401A or Keithley 2000, 2015 etc.

I was considering buying either a Siglent or a Rigol DMM, and went on to TEquipment's site to compare prices.  Looks like they don't stock Siglent anymore.  Does anyone know when they stopped (and why) ?

Does it matter ?  :-//

Are these sort of performance numbers just mathematically calculated, tested and verified on actual instruments or just copied from the competing products datasheet?
Looking at a SDM3045X Cal cert, specifications are checked against a Fluke 5522A multi product calibrator and its SN# is also listed for traceability. Once there's some 3065X's in the wild we'll have some idea if they use the same calibrator....I guess they would.
Should have mine late next week.

A sheet with calibration results is just a snapshot. It says nothing about the long(er) term stability of an instrument. For the latter you have to rely on the specifications so the question of H.O still stands. The specifications also seem to match the Keysight 34465A DMM. It takes some serious volt nuttery and experience to get to these levels of long term stability performance.

SDM3065X. We have the official price and presence at American and European Siglent sites. 729$ and 689€. Still remains a little bit expensive for me.

http://siglentamerica.com/pdxx.aspx?id=5211&T=2&tid=37.
http://siglenteu.com/pdxx.aspx?id=2773&T=2&tid=37.

So, simone.pignatti (Batterfly) you have to "reduce" the list price.   ;) The coupons for the members remains a very good idea for those who interested. (And maybe for other products too).

Some pics for comparison as the SDM3065X is ~50mm longer than its 2 little brothers:



From top to bottom: SDM3045X, SDM5055 and SDM3065X



Measuring 6V Gell cell.
Note: SDM3045X has different measuring ranges but while it did not display Overload on its 6V range for some better comparison was switched to next range up: 60V while SDM3065X and 3055 were on 20V range.


Heeeelp, I'm turning into a Volt nut.  :scared:
