The horns are nice if the SDM30xx are beeing used as portable devices but on a desk or shelf I do not like them.
I am wondering if you can mount the front bumper-horns rotated by 180° (=showing to the back), so they are out the way. It would be quite clever from Siglent and indeed it looks like they can become unscrewed and remounted again rotated.
The front "horns" can indeed be rotated 1800, the stacking notches and all 4 screw holes still align.
But, there is a small ridge on the underside that rolls over the front face of the instrument when installed correctly and this would need to be removed with a sharp knife before reversal to get them to fit nicely.
This ridge is ~3mm wide and 1mm high and the feet/horns firm rubber type should not make it too difficult to accomplish this mod at home for those that need to.  :-/O


Thanks for the suggestion, we'll pass it on.

Anyone got a calibration manual for the SDM3055?

Not seen one from Siglent yet.
AFAIK they should have it finished by now, it was some time ago when I asked for the Service manual.
All their Service manuals have the Cal procedures outlined and the equipment needed.
To give some idea I listed an overview for the full Siglent range here:
https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/msg986796/#msg986796

It'll be ~30hrs till tech support are at work at the factory, we'll try to get some answers for you then.

BTW have you got one that's faulty?

Hey guys,

I've just recently got one SDM3045X and although I had no time to test it thoroughly, there are minor issues with it which are annoying a lot:

- blinking (breathing) power led. It is an instant wtf - you just cant do anything at your workplace without disturbing your focus by this tiny led. I will kill the multivibrator in his head but for now the only protection is a small piece of duct tape. What is the reason behind this? Driving the users mad? Luckily it is not beeping continuously at power off.
- the font used on main screen is just partly monospaced: the minus/plus signs has different width. Because of that, when the DUT is not connected, the numbers on the screen is constantly jumping to left and right. Super annoying and it could be resolved easily by using a proper font...
- the plastic horns are upside down comparing to my SDG2042X, therefore it was impossible to stack these on top of each other (I resolved by flipping the horns upside down on SDG2042X, but one of the screw nuts just falled inside the casing.
- the display becomes super slow when the bargraph is on. Sure, it takes some cpu cycles to calculate and show the bargraph, but c'mon...
- you cannot set the display brightness (background lighting)

and I just used it for 5 minutes :palm:

Is there a firmware update available for the SDM3045x?
I found nothing on the official product page. Maybe it is not the right place to look?

Cheers

Looks good tautech! Have not seen any prices yet, but they will show up soon I guess. Well, since I already have both a SDM3055 and 34461A I rather stop buying just because they look nice and no, I am not that rich  :=\

Happy new year to everyone,

Yeah great news. With the new X series look, but the price (7980 ¥ about 1150 US $) looks more expensive than Keysight 34461. So .... between the two models i choose Keysight 34461A with Benchvue software.
But this is my personal choice ...

Who knows were the price point will be set ?  :-//

SDM3045X $389
SDM3055   $469
SDM3065X  ? ? ? and $1150 seems unrealistic.

We've seen this before with other models..... the Chinese price bearing no relation to western market pricing.

A very good choice in the lower budget looks the new 3055X :

(With variable diode voltage from 0 to 4 V as i can see in translation in comparison with the older 3055)

Hi,
Here some updates from our friend from Batterfly in Italy :

http://www.batterfly.com/shop/multimetri-da-banco/siglent-sds3065x

If the price is right it seems to be a "Legend" for 6 1/2 Digits !

And the Datasheet in English :

Damn me hands are getting all sweaty. That would be beautiful to form a 3 unit row with 2xSDG2000X I have. Would be good unit to test & tear for Dave  :-+

It may not be any little different to the existing SDM3055.
Dave's already had a good look at the 3055, the link to it was in the OP:

Hi tautech,

What you mean when you say: "little different" ?
I'm sure you know something better than we know ...   ;)

I just want it to be accurate. I have borrowed a very good reference, and my Brymen is spot on. Not the Siglent unfortunately.

All the 1 year accuracy specs are listed in the Datasheet, I'm interested to know which measurement ranges fall outside those specs ?

It may not be any little different to the existing SDM3055.
I compared the data sheets and think they are different.
The old 3055 has high input impedance up to the 2V range. The 3065x up to the 20V range  :-+ . The DCV front end should be different. I think the 3065x will be using a bootstrapped input amplifier.
The 3055 has two current shunts, the 3065x has three.
And I expecting a LM399 voltage reference in the 3065x.

Real trusted full accuracy test data please.
Also real data about "trusted very good reference".
If practice and theory is not equal it tells that used application of theory  is wrong or the theory itself is wrong.
It is much easier to think an apple fall to the ground than to think that the earth and the apple will begin to move toward each other and collide.

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