New Siglent SDM4000A series Multimeter

[KungFuJosh]

Really? Do you have so many multimeters to replace a 16 ch. scanner card?

Go look at one of Tony's youtube videos and you can see for yourself. 🤣

I think the main reason for not allowing a user upgrade to the SC version is likely the voltage rating of the connector used for the scanner. So already having the connector installed could limit the maximum safe voltage. Another point could be just the costs of the parts with only few units actually changed to the scanner version.

Personally, I think it was a crappy design choice that they shouldn't have hung on to for the new meters. The 3000 series was clearly a copy of Keysight's meters. Adding on a card there was probably an afterthought that changed a no card design.

Now, the 4000 series is clearly attempting to copy Keithley. The difference being that Keithley's system makes upgrading addon cards simple. The DMM6500 and DAQ6510 share the same analog board, but allow for two different types of scanner cards. Siglent should have followed this philosophy and made the SC card simply an optional upgrade. Why bother with 4 production lines, when you can do two? It makes no sense to me. They could have offered with and without the SC card as a simple optional addon.

Sadly yes... a very bad case of TEA and its not only DMM's i love counter too... its bad....bad....

btw i have 2 videos or so about the 3065 scanner card on my channel, i made a breakoutbox (not very beautiful, but very useful)

I watched the one about SDM4065A-SC ... and yes I noted a few devices around but I didn't take the time to count the DMMs.

Indeed I noted he modified the DMM Check Plus adding SMA connectors ... nice one.

I think the fact that it would take time to count all the DMMs tells you everything you need to know. 🤣

[tonyalbus]

Closer look, also the rubber bumper changed compared to the Demo model.
notches have changed.

[tonyalbus]

Some quick shots... need new glasses, no clue what i am shooting.. can't get into the lab right now, but at least we have a quick look.

If this new Siglent SDM4000A DMM is even close to the price of the DMM6500, why would anyone consider it over the Keithley?

The DMMs at this level are intended for accurate, repeatable, precise measurements and the Keithley DMM6500 and Keysight 34461-5A have demonstrated such over many years/decades of doing exactly this, these are the "Benchmark" DMMs in this territory, and relatively new unknown for Siglent.

One reason is china is very hard to be independent of the "western market". Worst case scenario is china invades Taiwan, everybody gets angry at china, china builds a big wall around itself and then stops interacting with the rest of the world. I'm not sure how realistic this scenario is, but china is also not a "normal" country.

@tony:
Very good, then I don't have to open mine...

[coromonadalix]

ohhh  they use their own  SOM module   ... lm399   a classic

Is it normal for new Siglent equipment availability in USA to be delayed or is this a chump thing?

Probably the latter. US prices went up recently on the US Siglent site. I purchased a Siglent SPD4000X before the tariffs kicked in, and it is now 15% more., which is very reasonable. Not everything went up though. SDS800X HD did (5%), but SDS1000X HD did not (which is also reasonable). SDM3045X remained the same, but SDM3065X increased by 15%. I am curious what the SDM4000A is going to be. I originally thought the SDM4065A would be sold for around $980 (slightly less than $1000), but I now think it will be at least $1120.

No it's not normal and until the tariff dust settles there will be some uncertainty.
Just keep an eye on the US website.....sorry I don't have any insider knowledge.

Batronix has the 4055A and 4065A in stock. With the current special offer for the SDM3065X, you can choose between the 4055A and the 3065X, with a difference of just $3...
Higher precision vs. more modern design.
Why not both...

[Furna]

Why not both...

Because of the bank account.

I am curious to see the internals of the 4065A-SC ...

[Martin72]

It looks pretty much the same as tonyalbus's, except that the mechanic for the card has been added, along with the connections.
Oh, I didn't really want to open it...

Thank you ... yes the board looks exactly the same; even the scanner card data connector is present ...

[Martin72]

I will test the scanner card function soon.
Personally, I would like a second scanner card with fewer channels but higher voltage resistance.
Then it would also be suitable for work.

Thanks for sharing your pictures,
i see your inside fuse has a cover, while mine has not, maybe because of those cables close by.
and you have an extra fuse in the back
Did your seal also say: Calibration void and not Warranty void?  when seal broken?

[Martin72]

Hi,
Yes, it's now on everything, on my SDG6000X, SSG3000X...
Siglent must have ordered the wrong seals and now they're just using them up.

I think they finally ordered the correct seals. 😉

Lots of countries don't allow warranty void stickers, because they can't invalidate the warranty for doing basic service.

AFAIK warranty void stickers are illegal in the USA; they are not explicitly illegal in EU but are probably not enforceable due to the law governing the warranty.
I good sum-up at https://www.ifixit.com/News/74736/warranty-void-stickers-are-illegal-in-the-us-what-about-elsewhere

I appreciate Siglent opted to "lightly discourage" the practice of looking inside something that you *own*.
I guess they have the full right to declare the calibration voided if the sticker is broken ...

Probably every TE manufacturer or cal lab uses cal void if opened stickers.

Surprisingly (to me) the one that doesn't is Fluke.  They have little round stickers that go over the actual CAL button if it is externally accessible, but that's it.  If you send something to them for calibration, it comes back with a little peel-off sticker (like from the DMV) that is still on the form so you can leave it there or put it where you want.  The bench meters have a little outline where it is supposed to go but putting it there does not obstruct any screws or anything.  Now if I send the same meter to Joe's All-Pass Calibration Lab and Sticker Store, I'll get it back looking like it is wrapped in crime scene tape.
