Siglent SDM3065X
« on: May 26, 2018, 06:08:22 pm »
Hi guy's,

I would like to buy a 6 1/2 digit multimeter with trending capability without breaking the bank  :-DMM

Of course there is Keysight, Keithley, PeakTech and Siglent....maybe some other.  :=\

When I look the the datasheet the Siglent SDM3065X seems to be a winner when I look to the price/performance.

Service from Siglent is maybe not yet on the level of Keysight.

Thank you for sharing your experience if you have such a multimeter.  :scared:

Thread about all the SDM3k models:

I've got one with the 16ch logging card if there's anything you want me to check for you.
I sold another one to member Defpom and he uses it for his repairs on his YouTube channel....easy to find him if you look.

I check already the Defpom 2hour video but it does not show any test about accuracy, is more relate to use the the multimeter.

Nobody connect it to a calibrator ar compare to a Keysight 34465A?

You only need compare the datasheets, on my one the Cal cert specifies it was calibrated with a Fluke 5522A which was 3 months inside its Cal period so should ensure the specified datasheet accuracy. There's also a specified 1 year accuracy listed.

Member kj7e had one but I think he updated it for 7.5 digits or more.
He had a rough start with his and got another one from Siglent USA.
His first impressions are here:

The cal sheet doesn't really guarantee anything. Peope doing tests with calibrators and way better instruments found some accuracy related bugs in the Keysight 3446xA series DMMs for example (which got fixed by a firmware update after Keysight reproduced it).
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Ive had both the SDM3055 and SDM3065, both where calibrated from the factory bang on and worked quite well.  They are good meters for the price.  My experience has been, Siglent seems to do a proper job with their factory calibrations.

As pointed out, my first SDM3055 had an issue, I never even removed the plastic wrapping as I could hear something rattling inside the meter when I unboxed it.  The distributor I bought it from was not as helpful as I would have liked, but Siglent USA stepped in and quickly resolved the issue.

For the accuracy and longer time stability it is very difficult to tell how good the new meters are actually. There is a little more trust in the way Keysight or Keithley calculate the specs, but time will tell.  Just measuring a few new meters against a more or less accurate source does not give much information. The old established companies have there experience with older models.  At least the LM399 is about the same for all.

^Agree, I think the Siglent specs are honest, but Keysight specs are conservative.

From the Keysight 34401A DMM service manual (see attached):

"The Agilent 34401A is designed and tested to meet performance better
than mean ±4 sigma of the published accuracy specifications."
