Siglent Bench DMMs SDM3065X, SDM3055 and SDM3045X

[lugamodder]

I am currently in the process of choosing an affordable bench multimeter for hobby use and am considering purchasing the SDM3045X. Upon closely studying the datasheets, I found that the datasheets from different versions show significantly different accuracy levels.

For example, in the datasheet from Siglentna and Siglenteu (https://siglentna.com/wp-content/uploads/dlm_uploads/2023/02/SDM3045X_DataSheet_E04A.pdf), the DCV accuracy for the 6V range is 0.06% + 8, while in the older datasheet from Welectron (https://www.welectron.com/mediafiles/datasheets/siglent/Siglent_SDM3045X_Datasheet-Web.pdf), it’s 0.02% + 6. Does anyone know which is correct? Or is there currently a new 'improved' version of the device being released?

Do these DMMs still suffer from the 2V relay click or has this been solved with a firmware update?

SDM3045X ?

thanks, so the solution is to get the chinese x-e version or buy the 3055x.

Note that some newer hardware versions without public firmware of the 3045X cannot be improved (yet?).

If you can afford the 3055, get that instead, as it is superior hardware.
