I think I did already? 😉

We need an SCPI command to return control to the local device (in this case Siglent DMMs) after the device has been controlled remotely.
Can you check EasyDMM behavior ?

I believe this might hold clues are to whether there is a bug or if additional SCPI commands are required to preserve user settings.

That was my first thought, but I didn't find any kind of useful logs with it, and I don't have anything setup to monitor what commands it's sending. Do you have a suggestion for that?

EasyDMM doesn't have the reset issue at all. Connect/disconnect states are set without messing anything up. Though it mostly sucks by comparison beyond that. 😉

Nothing at all apart from some advanced sniffing.
Anyways, member Mortymore might have offered a solution.  :-+

"To exit remote mode on the SDM3055/SDM3055A Digital Multimeter without using the *RST command, you can use the following alternative method:

Send the command "*CLS" to clear the status registers and error queue.
Send the command "SYSTem:LOCal" to switch the instrument from remote mode to local mode.
By sending these two commands sequentially, you can effectively exit remote mode on the DMM without performing a full reset using *RST. This method allows you to maintain the current configuration and settings of the instrument while switching back to local mode."


If it works or not...  :-//

It didn't work for me, but that could be a PEBKAC error. I tried SYSTem:LOCal, SYST:LOC, syst:loc and none of that did anything to exit the remote state.

Currently, this is what the exit command is:
; Final command to meter before breaking connection
#finalCmd abort;*cls;*rst

Thanks,
Josh

VXI-11 bus, not SCPI for EasyDMM. It uses a "destroy_link" command.

To return to local control, just press the shift key :-) this only works if you do not have any data being actively received by TC, so don't have a grid panel open or the "current values" tab open, if you are actively communicating with the meter you will see the display flick briefly to local and then revert back to remote.

Thank you! That's a great workaround until Rob gets them to add the SCPI command. My only concern is for after shutting down TC, so that works great.

And it takes a while to install both updates, ~5min.
New messages appear on screen and when the upgrade is successful.

1. Added software options for accessory SCD30A.
Yes, this:

Will test SCD30A for extended periods during our 3 day EMEX show next week.

It should work on all their DMMs including the SDM3055X-E. 😉

It seems that the changelog is a little messed up. I see different information and the date doesn't match either.

By the way, what is meant by EMMC Flash that is now supported?

Very interesting, but this point...

...
3. After upgrading to version 1.02, you cannot return to version 1.01
...

...let me, if there are still bugs, be very careful and reserved.
Anyone who has not only had to wait for months but years and in the meantime only survived through the return to an older version, hopefully understand this.

I was no longer informed for a long time. Maybe Siglent is now interested in doing everything better for his buyers ?

Just got a new SDM3065X in, and the firmware shows 3.02.01.13

I checked to see if I needed to flash this before putting it in service, but this code version doesn't appear available to download and is N+1 rev higher than the version on the site.
3.01.01.12R1

It's been a long week; maybe I've got something wrong.

You're fine. Your DMM came with newer firmware than what's available to download. That happens, especially on newer devices before a fw revision is released for download.

You likely won't be able to flash any firmware until a new branch is posted that starts with 3.02.xx.xx.

My DMM arrived with 3.02.01.12R1.

SCD30A 30A shunt for SDM3055/65X

In the recent EMEX 3 day exhibition we did a prolonged run with the new 30A shunt and compared accuracy reported on SDM3055 vs the SDL1030X Eload.
Eload was set in CC mode @5A with SPD3303X-E in Parallel mode supplying the current.

3-4mA variance was most seen which IMO is pretty decent calibration of a 30A capable shunt extending SDM 10A range to 30A capability.

Nice little gem, like the form factor.
Other ranges (upper) avaible ?

Seeing nothing on the Chinese website Martin.
Was pretty pleased with its performance although I haven't pushed it past 5A......yet !

Might get to do that this weekend, stay tuned as I have 60A from SPS5042X available.  >:D

Is there already experience with the new 1.02 .... generation of the 3055 firmware ?

Edit:
As it looks, there was a change to V1.02.01.28 on the same day when the V1.02.01.27R2 appeared  ::)

SDM3055 with SCD30A accessory shunt 20A test.

Supply at 10V 25A setting from SPS5042X (60A capable) into SPL1030X set to CC 20A load.
Hookup wires used 2.5mm2 (12g) warmed slightly at near 20A as expected.
No Sense capabilities were used.

It looks like the SDM3065X can be had for 599.00 on SiglentNA clearance site:
https://siglentna.com/products/clearance/#

Not bad if you happen to be able to order from the NA site.

Yes, but it's important to note that it comes with a 1 year warranty instead of 3. Not sure about the cal cert either.

I just recently bought an SDM3055, but it still stuns me, that even if it is a brand new unit, latest firmware, etc, the meter is only 220 000 counts. Even the official data spec sheet cover shows a unit with 2.39999 DCV on it and clearly states that it is a 240 000 counts meter. I thought that older units were 220000 or something, but it is for sure has been resolved and they would not lie to the customers. Am I doing something wrong or misunderstand something?

Another thing is the otherwise nice feeling test probes are a couple hundred ohms when resting on each other by their weight. It is kind of unresponsive in continuity mode... While my Probemasters are near instant and less than 0.1 ohm.
