Was 2018 a bad year for Siglent SDM3055 ?

for failed units they don't provide data.

That seems very odd to me.  What particular service did you request (ISO17025, Z540 w/ data, etc?)  I haven't used Transcat, but typically the lowest service I've been offered by others (Z540 w/ OOT data only or something like that) will provide at least the as-found data for any range found to be out of spec.  You need that in case review and/or remediation is needed due to the out-of-tolerance condition.  In your case that obviously isn't an issue.

It's mind boggling that the SOP would be to scrap these meters because they are not only non-repairable but also non-adjustable.  I wonder where the scrapped units go?  I haven't seen them show up on eBay as "pulled from a working environment".

I was wrong about this, when I picked them up, they gave me complete data. I'll see if i can dig up the original paperwork for these

Are they consecutive SN#'s ?

There is a very small possibility the OEM Cal was wrong due to expired Cal equipment.....thinking out loud....

Interested in NA HQ response.
 

they are all within ~400 of each other

if Siglent responds I'll update this post

If it is permissible, could you post the data or at least the OOT results?  I'd be curious to see if they are off by an amount that should be fixable with calibration or if they're so far off that they're broken.

I'm glad to hear that they provided data.  I've not used them, but Transcat has a very good reputation and I hope they don't go to the dogs as some companies have.

It's been a while so I thought I'd update this. After going back and forth, it has come to light that even after the firmware update, no adjustment was performed. So the data won't be useful to problem solve.

 I've been attempting to engage the manager of that particular lab about why and how this broke down and he's stopped returning email. I'm too busy to keep trying to problem solve on this, but this has been very, very disappointing.

I've been in contact with Siglent NA I wont reproduce the full emails here, but this is the most relevant quote:

"I appreciate the response. I will work on them having better information and using it better. They contact us all the time and request quotes for their customers. We have several instruments in house now that went to transcat first, had an issue, and are getting an adjustment at our facility."

So Siglent is at least paying lip service to make this better. they also mentioned that they have been working more with Trescal lately. I've gotten an RMA from Siglent to ship these back to Ohio to be adjusted.

Thanks for the update.
