Can you please try to replicate the mains switch-off problem that I am seeing?
Switch unit on, power-up either channel 2 or 3, say 12v. Soft power off, observe 0v. Then switch off the unit via the mains switch. Do you observe any power glitch from that channel at that time?
I’m thinking this may be specific to the SPD4323X or just my unit, since everyone who has responded has one of the other models.
Thanks to all for your time, including Tautech who has also very kindly responded on PM.
Best regards
Sean

As I mention above, no issues with that, I also show it in the footage I shot.
TheDefpom:
I found an interesting thing.. all of the actual voltage, current and power responses over SCPI are up to 6 decimal places...
See this yourself, send it these and see what you get back!
MEAS:VOLT? CH1
MEAS:CURR? CH1
MEAS:POWER? CH1
I am working on the Test Controller definition right now, I have it working already but I'm just tweaking things to tidy it up before I publish it :-)

Thanks Defpom, I didn't think to start playing with SCPI.
Confirmed on SPD4121x too; it is in the User Manual/Programming guide as well at pag. 72
Escape character is '^]'.
MEAS:VOLT? CH1
3.003907
MEAS:CURR? CH1
0.019987
MEAS:POWER? CH1
0.060029

That is really interesting.
Meanwhile I noticed that upgrading the firmware the LAN config was reset; not a big issue for me since I use DHCP but I had to go back in the LAn config and re-enable DHCP.
Thank you a lot for your effort on the Test Controller definition and can't wait for the video!

Before I can publish the Test Controller definition I need a bit of info about the other units.
Can people please confirm the absolute maximum settings for voltage and current on each unit, the data sheet gives general setting only but they can go over that slightly, the quickest way is to select the first digit and spin the encoder clockwise, it will max itself out.
For instance my SPD4306X does the following
Ch1: 15.15V/1.515A
Ch2: 30.3V/6.06A
Ch3: 30.3V/6.06A
Ch4: 15.15V/1.01A
(these are seperate as the data sheet shows these may NOT actually be doubled on some units)
Ch2 Series: 60.6V/6.06A
Ch2 Parallel: 30.3V/12.12A
Please list in the same way, once I have this information I can publish then test controller definition.
